Performance of the latest/best
Intel AHCI and RAID Drivers

(last updated at 09/18/2017)


Introduction
According to my experiences Intel has optimized their RST/RST(e) drivers for the usage under the following conditions:
  • favoured storage disks: SSDs
  • favoured Intel Chipsets and their related Intel SATA AHCI/RAID Controller models: depending on the drivers release date the currently available up-to-date ones
  • favoured Operating System: Windows 8.1 and - even better - Windows 10
So it should not be a surprise, that there is no "ideal" Intel AHCI/RAID driver available, which will work rock stable and give the best performance with all Intel chipset systems. At the end each user has to find out himself, which version of the various Intel AHCI and RAID drivers suits the best his special hardware configuration and personal preferences.

Own benchmark tests
Beginning in February 2013 I have done a lot of benchmark tests running Win8/8.1/10 x64 in AHCI and RAID mode with different more or less up-to-date Intel chipset systems (Z68, Z77, Z97 and Z170) and different AHCI/RAID driver versions.
I wanted to find out, which AHCI resp. RAID driver is giving the best possible performance for users with a reasonably new Intel chipset hardware configuration.
My tests were done with the following different hardware configurations and SATA modes:
  1. Intel 6-Series Chipset AHCI system (ASUS P8Z68-V with a 512 GB Samsung 840 Pro SSD running in AHCI mode), latest tests done in August 2017
  2. Intel 6-Series Chipset RAID0 system (ASUS P8Z68-V with 2x256 GB Samsung 840 Pro SSDs as RAID0 array, stripe size: 64 KB), latest tests done in December 2016
  3. Intel 7-Series Chipset AHCI system (ASUS P8Z77-V with a 512 GB Samsung 840 PRO SSD running in AHCI mode), given away in April 2015, latest tests done in January 2015
  4. Intel 7-Series Chipset RAID0 system (ASUS P8Z77-V with 2x256 GB Samsung 840 PRO SSDs as RAID0 array, stripe size: 128 KB), given away in April 2015, latest tests done in January 2015
  5. Intel 9-Series Chipset AHCI system (ASRock Z97 Extreme6 with a 1 TB Samsung 850 EVO SSD running in AHCI mode), latest tests done in November 2015
  6. Intel 9-Series Chipset RAID0 sytem (ASRock Z97 Extreme6 with 2x256 GB Samsung 840 PRO SSDs as RAID0 array, stripe size: 64KB), latest tests done in November 2015
  7. Intel 100-Series Chipset AHCI system (ASRock Fatal1ty Z170 Professional with a 512 GB Samsung 840 Pro SSD running in AHCI mode), latest tests done in September 2017
  8. Intel 100-Series Chipset RAID0 system (ASRock Fatal1ty Z170 Professional with 2x256 GB Samsung 840 Pro SSDs as RAID0 array, Stripe size: 64KB), latest tests done in June 2017

Although the results are not 1:1 transferable to other systems, they may be helpful for other users with an actual Intel system, who are searching for the "best" AHCI resp. RAID driver.

Preparations and test conditions
In order to perform this benchmark comparison tests under quite similar conditions, I have started my tests with a clean "EFI mode" install of Win8 x64 resp. Win10 x64 in AHCI resp. RAID mode onto my freshly secure erased SSD(s). Once the OS was up, I have done the normal performance boost settings I have layed down >here< for AHCI users and >here< for RAID users.
After having
  • a) installed all Windows Updates,
  • b) executed the "Windows Experience Index" (to let the OS detect the SSD) and
  • c) emptied the Recycle Bin,
  • d) used the "TRIM trigger" option of "Anvil's Storage Utilities" or run the Win8.1/10 "Optimizer" (to TRIM the system drive C:),
I started my benchmark tests with the Win8/8.1 x64 in-box AHCI resp. RAID driver. After having "benched" the generic Win8/8.1 standard AHCI/RAID driver, I replaced it by different Intel AHCI/RAID drivers, which were manually installed from within the Device Manager.
All benchmark tests were done on the Win8/8.1/10 x64 system partition (drive C:) and without any CPU/memory overclocking. To get as realistic results as possible, nothing has been additionally done to boost the benchmark results (e.g. running in safe mode, disabling any Windows Services or Antivirus running in the background, disabling the CPU C-States within the BIOS).



Comparison of different AHCI drivers

A. Test results with a Z68 system running in AHCI mode
(all tests done at 08/03/2017)


Test system:
  • Chipset: Intel Z68 (mainboard: ASUS P8Z68-V, BIOS version: 3603)
  • SSD: ca 4 years old and heavily used 512 GB Samsung 840 PRO
  • OS: Windows 10 x64 Pro v1703 ("Creators Update") Build 15063.502 incl. all Hotfixes, freshly installed at 08/03/2017 in UEFI mode

Tested AHCI drivers:
  1. Win10 in-box MS Standard AHCI driver (name: storahci.sys, shown as being dated 12/03/2016)
  2. Intel RST driver v11.2.0.1006 WHQL (dated 05/30/2012, last "conventional" Intel RST Series AHCI driver)
  3. Intel RST(e) driver v11.7.4.1001 WHQL (dated 03/05/2013, latest driver from the RST(e) v11 platform)
  4. Intel RST(e) driver v12.9.4.1000 WHQL (dated 04/07/2014, latest driver from the RST(e) v12 platform)
  5. Intel RST(e) driver v13.1.0.1058 WHQL (dated 05/28/2014, latest driver with native support of Intel 7-Series Chipsets)
  6. Intel RST(e) driver v13.2.8.1002 WHQL (dated 07/09/2015, latest driver from the RST(e) v13 platform)
  7. Intel RST(e) driver v14.8.16.1063 WHQL (dated 04/10/2017, latest driver from the RST(e) v14 platform)

Notes:
  • Since the Intel RST(e) drivers from the v13 and v14 platform natively do not support Intel 6-Series Chipsets, I forced the installation of the original drivers by simulating to have a supported chipset.
  • Intel RST(e) AHCI drivers from the v15 platform haven't been tested again, because I knew from previous tests, that they do not work properly with my Z68 Chipset system.

Here are my test results:
  1. MS Win10 in-box AHCI driver:

  7. Intel RST(e) driver v14.8.16.1063 WHQL:

    Z68-AHCI-148161063.png - Bild entfernt (keine Rechte)

Evaluation of the benchmark results:
  • All tested Intel AHCI drivers from v11.2.0.1006 up to v12.9.4.1000 were running fine and fast with my Z68 system. The differences regarding the READ, WRITE and TOTAL scores are only marginal and probably not even noticeable by the user.
  • Due to the absolutely best 4K READ and WRITE scores, the winner was again the old Intel RST driver v11.2.0.1006. The scores of the Intel RST(e) drivers v11.7.4.1001 and v12.9.4.1000 were almost as good (except the 4K ones).
  • According to my test results neither the generic MS AHCI driver nor the RST(e) AHCI drivers, which belong to the v13 or v14 platform, seem to be the best choice for Intel 6-Series Chipset systems running in AHCI mode. The only exception was the Intel RST(e) driver v13.2.8.1002, which gave my Z68 system not the best, but a rather good performance.

Ranking of the best performing AHCI drivers for my Z68 System:

  1. Intel RST driver v11.2.0.1006
  2. Intel RST(e) driver v11.7.4.1001
  3. Intel RST(e) driver 12.9.4.1000
  4. Intel RST(e) driver v13.2.8.1002

Recommended AHCI drivers for Intel 6-Series Chipsets:
  • Since all 3 "winners" of my Z68 AHCI benchmark tests gave me quite similar results, I recommend to take the latest of them, the Intel RST(e) driver v12.9.4.1000.
  • Users, who want to use a much newer Intel AHCI driver, should try the Intel RST(e) v13.2.8.1002. Since this driver natively doesn't support Intel 6-Series Chipsets, the installation has to be forced.



B. Test results with a Z77 system running in AHCI mode
(all tests done in January 2015)


Test system:
  • Chipset: Intel Z77 (mainboard: ASUS P8Z77-V, BIOS version: 2104)
  • System Drive: 512 GB Samsung 840 Pro
  • OS: Windows 8.1 x64 Pro incl. all Hotfixes, freshly installed in UEFI mode

Tested AHCI drivers:
  1. Win8.1 in-box MS Standard AHCI driver (name: msahci.sys)
  2. Intel RST driver v11.2.0.1006 WHQL (dated 05/30/2012, last "conventional" Intel RST Series AHCI driver)
  3. Intel RST(e) driver v11.7.4.1001 WHQL (dated 03/05/2013)
  4. Intel RST(e) driver v12.8.13.1000 WHQL (dated 03/24/2014)
  5. Intel RST(e) driver v12.9.4.1000 WHQL (dated 04/24/2014)
  6. Intel RST(e) driver v13.0.4.1000 WHQL (dated 04/18/2014)
  7. Intel RST(e) driver v13.1.0.1058 WHQL (dated 05/28/2014, latest original driver with support of 7-Series Chipsets)
  8. Intel RST(e) driver v13.2.4.1000 modded by me (dated 07/25/2014)
  9. Note: Newer Intel RST(e) AHCI drivers could not been tested, because I gave my Z77 system away in April 2015.

Here are my test results:
  1. MS Win8.1 in-box AHCI driver:

  8. Intel RST(e) driver v13.2.4.1000 mod by me:

    Anvil-Z77-Win8.1-AHCI-13241000.png - Bild entfernt (keine Rechte)

Evaluation of the benchmark results:
  • All tested Intel AHCI drivers from v11.2.0.1006 up to v13.2.4.1000 were running fine and fast with my Z77 system. The differences regarding the READ, WRITE and TOTAL scores are only marginal and probably not even noticeable by the user.
  • This time it was the Intel RST(e) driver v12.8.13.1000, which gave my Z77 AHCI system the best benchmark results, but the final results were very close. The scores of the Intel RST(e) drivers v12.9.4.1000 and v13.2.4.1000 were almost as good.
  • Neither the MS AHCI driver nor Intel's newest RST(e) driver versions seem to be the best choice for Intel 7-Series Chipset systems running in AHCI mode.

Ranking of the best performing AHCI drivers for my Z77 System:

  1. Intel RST(e) driver v12.8.13.1000
  2. Intel RST(e) driver v13.1.0.1058
  3. Intel RST(e) driver v12.9.4.1000

Recommended AHCI drivers for Intel 7-Series Chipsets:
  • Since all 3 "winners" of my Z77 AHCI benchmark tests gave me nearly similar results, I can recommend all of them.



C. Test results with a Z97 system running in AHCI mode
(all tests done in November 2015)


Test system:
  • Chipset: Intel Z97 (mainboard: ASRock Z97 Extreme6, BIOS version: 2.50)
  • System Drive: ca. 1 year old and already heavily used 1 TB Samsung 850 EVO SSD (secure erased before the OS installation, TRIMed before each single test)

    Anvil_Z97-AHCI_1TB-Samsung-850-EVO_14801042.png - Bild entfernt (keine Rechte)

Evaluation of the benchmark results:
  • All tested Intel RST(e) drivers (from v12.9.4.1000 up) gave my Z97 AHCI system a good performance.
  • The benchmark result differences between the tested Intel RST(e) drivers are not big and probably not even noticeable at daily work.
  • Although the brandnew Win10 in-box MS AHCI driver has a good performance, all tested Intel RST/RST(e) drivers gave me noticeable higher total scores due to their much better WRITE performance.
  • Interesting result: Although the Intel RST(e) driver v12.9.4.1000 natively doesn't fully support Intel 9-Series AHCI systems, this driver gave my Z97 system better results than many Intel RST(e) drivers of the v13 and v14 series.
  • The Intel RST(e) drivers of the v14.6 series seem to be not the best choice for Z97 AHCI systems.

Ranking of the best performing AHCI drivers for my Z97 System:
  1. Intel RST(e) driver v13.2.4.1000
  2. Intel RST(e) drivers v14.8.0.1042 and v14.7.0.1000 (note: the test results differed extremely, the best was taken)
  3. Intel RST(e) driver v13.5.2.1000

Recommended AHCI driver for Intel 8- and 9-Series Chipsets:
  • Intel RST(e) driver v13.2.4.1000 (well developed for these chipsets, good performance, very stable)



D. Test results with a Z170 system running in AHCI mode
(all tests done on 09/17/2017)


Test system:
  • Chipset: Intel Z170 (mainboard: ASRock Fatal1ty Z170 Prof. Gaming i7, BIOS version: 7.31)
  • Tested Disk Drive: ca 3,5 years old and already heavily used 512 GB Samsung 840 Pro SSD
  • OS: Windows 10 x64 Pro v1709 Build 16288.1 incl. all Hotfixes, freshly installed in UEFI mode

Tested AHCI drivers:
  1. Win10 v1709 in-box MS Standard AHCI driver v10.0.16288.1 dated 09/10/2017 (name: storahci.sys)
  2. Intel RST(e) driver v13.2.8.1002 dated 07/09/2015 (latest v13 platform AHCI driver Intel has ever released for the public, I used the mod+signed variant, because Intel Z170 chipsets are natively not supported by the original driver)
  3. Intel RST(e) driver v13.44.0.1026 dated 02/22/2017, composed, modded and signed at 09/16/2017 (contains the untouched Intel iaStorAV.sys file v13.44.0.1026)
  4. Intel RST(e) driver v14.8.16.1063 WHQL dated 04/10/2017 (currently latest Intel RST driver from the v14 platform)
  5. Intel RST(e) driver v15.2.16.1060 WHQL dated 03/30/2017 (currently latest Intel RST driver from the v15.2 series)
  6. Intel RST(e) driver v15.5.5.1059 WHQL dated 06/01/2017 (currently latest Intel RST driver from the v15.5 series)
  7. Intel RST(e) driver v15.7.5.1025 WHQL dated 08/10/2017 (currently latest Intel RST driver from the v15.7 series)

Here are my test results:
  1. MS Win10 v1709 in-box AHCI driver:

  7. Intel RST(e) driver v15.7.5.1025 WHQL:

    Z170-AHCI-v1709-15751025.png - Bild entfernt (keine Rechte)

Evaluation of the benchmark results:
  • All tested Intel AHCI drivers were running fine and fast with my Z170 system.
  • The performance differences measured by the benchmark tool, were minimal and will not be noticeable while working.
  • Absolutely surprising result: The performance winner was my modded Intel AHCI driver v13.44.0.1026, which natively doesn't exist. (Intel has only released the related RAID variant to Microsoft for being used as Win10 v1709 in-box RAID driver.)
  • Due to their very good WRITE scores both RST v13 platform test candidates (v13.44.0.1026 and v13.2.8.1002) gave my Z170 AHCI system a better performance than all other tested AHCI drivers.
    Interesting: The best performing Intel AHCI drivers are either not released by Intel (v13.44.0.1026) or natively do not support modern Intel Chipset AHCI systems from 100-Series up.

Ranking of the best performing AHCI drivers for my Z170 System:
  1. Intel AHCI driver v13.44.0.1026 composed+mod by me
  2. Intel AHCI driver v13.2.8.1002
  3. MS Win10 v1709 in-box AHCI driver v10.0.16288 and Intel AHCI driver v15.5.1059 WHQL

Recommended AHCI drivers for Intel 100-Series Chipsets:
  • Intel RST(e) AHCI driver v15.5.1059 or Microsoft's Win10 v1709 in-box AHCI driver (new drivers with new features)
  • Courageous AHCI users may try any of my performance winners, which belong to the RST(e) v13 platform (better performance, but without native support of modern Intel Chipsets)


Have fun with the best performant Intel AHCI drivers for your specific system!

Evaluation of the Z68 RAID0 benchmark results:
  • Due to their outstanding WRITE scores both tested Intel RAID drivers from the RST/RST(e) v11 platform gave me the by far best benchmark results, but the clear winner was the "classical" Intel RST driver/ROM combo v11.2.x.xxxx. Surprisingly the silver medal went to the Intel RST(e) driver v11.7.4.1001, one of the first Intel RAID drivers with additional SCSI filter driver. It was less performant than the winner, but with by far better scores than al the other tested and much newer RAID drivers.
    Note:
    It is not easy to get any of the old Intel RAID drivers with their outstanding performance properly installed onto Win8.1 or Win10, because the generic in-box Intel RAID driver is v13.2.0.1022, that means newer than the desired ones. According to my own experiences this problem can be solved the best way by removing the in-box Intel RAID driver from the ISO image and replacing it by the desired Intel RAID driver version according >this< guide.
    Personal comment: I doubt, that we will see in the near future a new Intel RAID driver with a better WRITE performance than the RST v11.2.0.1006.
  • Although Intel 6-Series Chipset systems are officially not supported by the Intel RST(e) drivers of the v13 series, they can be installed (by using the "Have Disk" option) and are working properly. Among the tested v13 Intel RAID drivers it was again the v13.2.8.1002, which gave my Z68 system the best scores.
  • Since I already knew from previous tests, that the newest Intel RST(e) RAID drivers from the v14 and v15 platform either cannot be properly installed or are running absolutely unstable, I haven't tested them again.
  • The test results verify, that
    a) the latest drivers are not automaticly the best, especially not for old hardware and
    b) the performance differences between the available Intel RAID driver/ROM combo versions are really noticeable, whereas these differences in AHCI mode are much smaller.

Ranking of the best performing RAID drivers for my Z68 RAID0 System:
  1. Intel RST driver v11.2.0.1006
  2. Intel RST(e) driver v11.7.4.1001
  3. newer, but much less performant: Intel RST(e) driver v13.1.0.1058

Recommended RAID drivers for Intel 6- and 7-Series RAID0 Systems:
  • Intel RST driver v11.2.0.1006 (by far the best performant driver for RAID0 systems)
    Attention: Don't try to "downgrade" any in use Intel RAID driver version from an RST(e) type (driver name: iaStorA.sys or iaStorAV.sys) to a "conventional" RST one (driver name: iaStor.sys)! After having rebooted you probably will get a BSOD!
  • Alternative RAID drivers:
    • a) for Intel 6-Series Chipsets: Intel RST(e) driver v11.7.4.1001 or v13.1.0.1058
    • a) for Intel 7-Series Chipsets: Intel RST(e) driver v13.1.0.1058 or v13.2.8.1002



B. Test results with a Z77 Chipset RAID0 configuration
(all tests done in January 2015)


Test systems:
  • Chipset: Intel Z77 (mainboard: ASUS P8Z77-V, BIOS version: 2104)
  • SSDs: 2x256 GB Samsung 840 Pro SSDs as RAID0 (stripe size: 128KB, both SSDs already heavily used, but secure erased before starting the tests)
  • OS: Windows 8.1 Pro (incl. all Hotfixes), freshly installed in UEFI mode (CSM enabled, LEGACY OROMs prefered)

Tested Intel RAID drivers:
  1. Intel RST RAID driver v11.2.0.1006 (dated 05/30/2012, latest "conventional" Intel RST driver) in combination with Intel RAID ROM v11.2.0.1527
  2. Intel RST(e) RAID driver v11.7.4.1001 WHQL (dated 03/05/2013) in combination with Intel RAID ROM v11.6.0.1702
  3. Intel RST(e) RAID driver v12.9.4.1000 WHQL (dated 04/07/2014) in combination with Intel RAID ROM v12.9.0.2006
  4. Intel RST(e) RAID driver v13.1.0.1058 WHQL (dated 05/28/2014) in combination with Intel RAID ROM v13.1.0.2126
  5. Intel RST(e) RAID driver v13.2.4.1000 WHQL (dated 07/25/2014) in combination with Intel RAID ROM v13.2.0.2134
  6. Intel RST(e) RAID driver v13.5.0.1056 WHQL (dated 09/10/2014, latest Intel RST driver at that time) in combination with Intel RAID ROM v13.5.0.2164
  7. Note: Newer Intel RST(e) RAID drivers could not been tested, because I gave my Z77 system away in April 2015.

Here are my test results:
  1. Intel RST v11.2.0.1006 WHQL:

Evaluation of the Z77 RAID0 benchmark results:
  • As with my Z68 system: The Intel RST RAID drivers v11.2.0.1006 are by far the best performant RAID drivers for all Intel 7-Series Chipsets.
    The only problem for the Intel RAID users is to get these "conventional" driver installed onto Win8.1 or Win10, but I found a way how it can be done (look into the start post of >this< thread ).
    Personal comment: I doubt, that we will see in the near future a new Intel RAID driver with a better WRITE performance than the RST v11.2.0.1006.
  • Although Intel 7-Series Chipset systems are officially not supported by the Intel RST(e) drivers from v13.2 up, they can be installed and are working up to the v14 line.
    Nevertheless I do not recommend to use any Intel RST driver with a higher version than v13.2.4.1000.
  • The test results verify, that
    a) the latest drivers are not automaticly the best, especially not for old hardware and
    b) the performance differences between the available Intel RAID driver/ROM combo versions are really noticeable, whereas these differences in AHCI mode are much smaller (see the post #1).

Ranking of the best performing RAID drivers for my Z77 RAID0 System:
  1. Intel RST driver v11.2.0.1006
  2. Intel RST(e) driver v13.2.4.1000
  3. Intel RST(e) driver v13.1.0.1058

Recommended RAID drivers for Intel 7-Series RAID0 Systems:
  • Intel RST driver v11.2.10.1006 (by far the best performant for RAID0 systems)
    Attention: Don't try to "downgrade" any in use Intel RAID driver version from an RST(e) type (driver name: iaStorA.sys or iaStorAV.sys) to a "conventional" RST one (driver name: iaStor.sys)! After having rebooted you probably will get a BSOD!
  • Alternative RAID drivers:
    • Intel RST(e) driver v13.1.0.1058 or v13.2.4.1000



C. Test results with a Z97 Chipset RAID0 configuration
(all tests done in November 2015)


Test system:
  • Chipset: Intel Z97 (mainboard: ASRock Z97 Extreme6, BIOS version: 2.50)
  • SSDs: 2x256 GB Samsung 840 PRO SSDs as RAID0 (stripe size: 64 KB, both SSDs already heavily used, but secure erased before starting the tests)
  • OS: Windows 10 x64 Pro "November 2015 Edition" (incl. all Hotfixes), freshly installed in "clean" UEFI mode (CSM disabled)
  • All RAID0 performance relevant settings according >this< thread were done.
  • Tested RAID0 volume: Drive C (system drive) with normally running OS and Antivirus (Windows Defender)

Tested Intel RAID drivers:
  1. Intel RST(e) RAID driver v12.9.4.1000 WHQL (dated 04/07/2014) in combination with Intel EFI RaidDriver v13.0.0.2075 (lower Raid Utility versions were not loaded at all by my ASRock BIOS)
  2. Intel RST(e) RAID driver v13.0.4.1000 WHQL (dated 05/06/2014) in combination with Intel EFI RaidDriver v13.0.0.2075

  10. Intel RST(e) RAID driver v14.8.0.1042 WHQL (dated 11/04/2015) in combination with Intel EFI RaidDriver v14.8.0.2377
Note: Other Intel RST(e) RAID drivers from the v11/v12 series could not been tested with my Z97 RAID system, because the Intel RAID ROM/EFI RaidDriver modules v11/v12 series were not supported by my Intel 9-Series chipset system. Furthermore my Z97 system doesn't admit the usage of any Intel RAID ROM/EFI RaidDriver module of the v11 or v12 series.

Here are my test results:
  1. Intel RST(e) v12.9.4.1000 WHQL (with EFI RaidDriver v13.0.0.2075):

Evaluation of the Z97 RAID0 benchmark results:
  • Compared to my Z68 RAID0 tests (see above) my Z97 RAID0 system gave me noticeable better benchmark results with all tested Intel RAID drivers, but contrary to my Z68 RAID0 tests I got no explicit performance winner.
    Possible reason:
    I was not able to test the Intel RAID driver v11.2.0.1006 with my ASRock Z97 Extreme6 mainboard. Its BIOS didn't admit the "downgrade" from the originally present Intel RAID ROM and EFI RaidDriver v13.0.0.2075 and the use of any "conventional" Intel RST RAID driver. Whatever I tried, I got a BSOD.
  • According to my test results the Intel RST(e) RAID drivers of the v14 series are not the best choice for an Intel 9-Series RAID system.

Ranking of the best performing RAID drivers for my Z97 System:
  1. Intel RST(e) driver v13.2.4.1000
  2. Intel RST(e) driver v13.1.0.1058
  3. Intel RST(e) driver v13.2.0.1022 (= Win10 in-box RAID driver, no matching RST Software available)
  4. Note: The absolutely best performing Intel RST RAID driver v11.2.0.1006 could not been tested with my Z97 RAID0 system (due to the ASRock Z97 BIOS limitations).

Recommended RAID drivers for Intel 8- and 9-Series Chipset RAID0 systems:
  • Intel RST drivers v13.1.0.1058 or v13.2.4.1000 (good performance combined with a perfect stability, recommended for all Windows Operating Systems from XP up)
  • Note: Users, who are able to get the Intel RST RAID driver v11.2.0.1006 installed and the matching Intel RAID ROM v11.2.0.1527 working, may benefit from a far better performance.



D. Test results with a Z170 Chipset RAID0 configuration
(all tests done at 24./25. July 2017)


Test system:
  • Chipset: Intel Z170 (mainboard: ASRock Fatal1ty Z170 Gaming i7, BIOS version: 7.30)
  • SSDs:
    Configuration A: 2x256 GB Samsung 840 PRO SATA SSDs as RAID0 (SATA connected, stripe size: 64 KB, both SSDs already heavily used)
    Configuration B: 2x250 GB Samsung 960 EVO NVMe SSDs as RAID0 (M.2 connected, stripe size: 64 KB, both SSDs rather new and nearly unused)
  • OS: Windows 10 x64 Pro v1703 ("Creator's Update"), freshly installed in "clean" UEFI mode (CSM disabled)
  • All RAID0 performance relevant settings according >this< thread were done.
  • Tested RAID0 volume: Drive C (system drive) with normally running OS and Antivirus (Windows Defender)
  • Since my mainboard BIOS doesn't allow any "downgrade" of the stock Intel RAID ROM/EFI modules, not all tests could be done by using the appropriate Intel EFI RaidDriver.

Tested Intel RAID drivers:
  1. Intel RST(e) RAID driver v13.2.0.1022 (= generic Win10 RAID driver dated 02/19/2015) in combination with the Intel RaidDriver v14.8.2.2397 (only tested in SATA mode with test configuration A)
  2. Intel RST(e) RAID driver v13.2.8.1002 WHQL dated 07/09/2015, latest driver from the v13 platform (in combination with the Intel RaidDriver v14.8.2.2397 (only tested in SATA mode with test configuration A)
  3. Intel RST(e) RAID driver v14.8.16.1063 WHQL dated 04/10/2017, currently latest from the v14 platform (in combination with the Intel RaidDriver v14.8.2.2397)
  4. Intel RST(e) RAID driver v15.2.16.1060 WHQL dated 03/30/2017, currently latest from the v15.2 series (in combination with the Intel RaidDriver v15.2.2.2775)
  5. Intel RST(e) RAID driver v15.5.2.1054 WHQL dated 04/24/2017, v15.5.4.1056 dated 05/12/2017 and v15.5.5.1059 dated 06/01/2017 (all in combination with the Intel RaidDriver v15.5.1.3017)
  6. Intel RST(e) RAID driver v15.7.0.1014 WHQL dated 06/06/2017, currently latest from the v15 platform (in combination with the Intel RaidDriver v15.7.0.3054)
Notes:
  • Intel RST(e) RAID drivers from the v11/v12 platform could not been tested with my Z170 RAID system. I was not even able to get the OS installed, although I had integrated the desired Intel RST driver instead of the original in-box Intel RST(e) driver v13.2.0.1022 according >this< guide.
  • Since only Intel RST(e) drivers from v14.6 series up do support NVMe SSDs as members of an Intel RAID array, I could not test any v13 platform Intel RST(e) RAID driver with the "Configuration B" system.


Here are my test results:

Evaluation of the Z170 RAID0 benchmark results:
  • The choice of the best performant RAID driver for modern Intel Chipset RAID systems is much easier than I expected. Contrary to the results I got while running my system in AHCI mode, my Z170 RAID0 system gave me extremely different results while testing the different Intel RAID driver versions.
  • Although I got absolutely different scores and moderately different performance rankings while doing my tests with an Intel SATA and an Intel M.2/NVMe RAID0 array, I got a clear winner with both RAID0 configurations due to its outstanding WRITE scores: It was the Intel RST(e) RAID driver v15.5.2.1054 dated 04/24/2017. It is not the latest, but currently the absolutely best performing Intel RAID driver I have ever tested with my Intel 100-Series Chipset system.
  • Interesting finds:
    • According to my test results the later released v15.5 series Intel RST(e) drivers v15.5.4.1056 and v15.5.5.1059 were clearly less performant than the older v15.5.2.1054 (= the winner).
      This verifies my very often given comment: Newer means not automaticly better!
    • Absolutely different was the performance of the Intel RST(e) RAID driver v15.5.5.1059 while running with the SATA RAID and M.2/NVMe RAID configuration. With the SATA RAID system it was the second in the ranking, but the last with the M.2/NVMe configuration.
  • As in my previously done benchmark comparison tests the old Intel RST(e) driver v13.2.8.1002 RAID driver gave me better results than many later released Intel RAID drivers (Rank 3 with my SATA RAID system).

Ranking of the best performing RAID drivers for my Z170 System:
  • A. Intel SATA RAID0 Configuration:
    1. Intel RST(e) driver v15.5.2.1054
    2. Intel RST(e) driver v15.5.5.1059
    3. Intel RST(e) driver v13.2.8.1002
  • B. Intel M.2/NVMe RAID0 Configuration:
    1. Intel RST(e) driver v15.5.2.1054
    2. Intel RST(e) driver v15.5.4.1056
    3. Intel RST(e) driver v15.7.1.1015

Recommended RAID drivers for Intel Z170 Chipset RAID0 systems:
  • Intel RST(e) driver v15.5.2.1054 (rather new driver with outstanding WRITE performance in RAID mode)
  • no real alternative available


Have fun with the best performant Intel RAID drivers for your specific Intel system!

@ 100PIER:

That are awesome benchmark results, much better than those I got with my 2x256GB Samsung 840 PRO RAID0 system.
Which Stripe size did you choose while creating your RAID0 array?

#5 RE: Intel RST(e) Drivers v12.7.0.1022 available by 100PIER 06.07.2013 22:17

Stripe size : 128 Ko.
I think my bench results are about 20% LESS than compared to some bench results i have seen on the net (for the same hardware), i don"t understand why.
the best ANVIL PRO result i got about 9610 (another bios and iRST versions) but far from 11000 +
(uploading function don't work at the moment, seem freezed?)

There are several tricks to push the benchmark scores (e.g. by executing the test on a totally empty RAID0 partition or by booting in safe mode).

After seeing a bench test with different stripe, the best reads an overall was a 16k, which is what I use, this seems to be also recommenced by Intel for RAID 0.

Stripe size : 128 Ko.

the best ANVIL PRO result i got is about 9610 (another bios and iRST versions) but far from 11000 +
(uploading function don't work at the moment, seem freezed? i can't send you a capture)

@odiebugs:
ASUS User Guide recommends a lower stripe size for server systems, and a higher stripe size for multimedia computer systems used mainly for audio and video editing.
Typical value for RAID 0 is 128 KB compared to 64 KB for RAID 5 or 10.

@ odiebugs:

I agree with 100PIER: The best stripe size for a typical RAID0 user is 64KB or 128KB (depending on the size of the files, which are mainly read and written).

Asus also said the Marvell 9128 was true Sata 3. ROLOL

A while back in the RST notes of Intel they recommended 16k for 2win 7 gen usage with SSD's. Also read that higher strip was better for servers.

Now looking for that info have come across a few benches, can't find the other info as the links are no longer there.

So now looking at some benches I see that 64k seems to be the best, as this is with HDD's and not SSD.

Here is one test, showing 64k to be the best, and the author said that 128k was nice but had some problems with it.

So do I say thanks, or I hate you because now I want to reinstall. LOL

The first option is better (for me). LOL

LOL, I hit both of yours Thanks buttons. Don't have a cow, ROLOLLMAO


I hope you realize that is a funny American saying, don't have a cow, not being disrespectful.

#13 New AHCI/RAID Benchmark Comparison Tests by Fernando 14.12.2013 20:03

Update of my Intel AHCI and RAID Performance Test Results

Yesterday I have completely rebuilt my Intel Z77 system from scratch. Now my 2 x 256 GB Samsung SSDs are running as single drives in AHCI mode and not anymore as members of an Intel RAID0 array.
The sense of this work was my interest to test the Samsung RAPID mode, which the brandnew Samsung SSD tool Magician v4.3 is now offering even for Samsung 840 Pro SSDs (look >here<).

This is what I have done:

  • Creation of a complete backup of my RAID0 partitions
  • Delition of my Intel RAID0 array
  • Secure erasure of both SSDs
  • Clean install of Win 8.1 Pro x64 in clean UEFI mode onto one of the Samsung 840 PRO SSDs
  • Optimization of the OS
  • Doing some benchmark tests with different AHCI drivers
  • Install of Magician v4.3 and activation of the RAPID mode
  • Redoing some benchmark tests with different AHCI drvers.

Within the start post of this thread you can find the test results, which I haven't expected at all.

Fernando, those results are unbelievable. Did you do IOPS benchmarks as-well ?

#15 RE: New AHCI/RAID Benchmark Comparison Tests by 100PIER 14.12.2013 21:50

Fernando,
I had the same idea as you on my Z77 PC, but not yet get time to do that.
can you bench with ANVILPRO and let us know the results ?
