Can you do a real transfer test between two single drives, with Rapid and not enabled.

I can't see how a drive can perform faster then it's max and the controllers max, wondering if the memory cache is affecting the bench.

---

It surely does. Up to 25% of the memory, but not more than 4 GB, are used by the RAPID mode for data caching.

Just wonder what the transfer difference is between non Rapid and Rapid.

---

You can see it within the benchmarks, which are within this thread. The transfer of big sized files is extremely fast with the RAPID mode, because it uses the memory for caching.
Nevertheless it is an illusion to believe, that a Samsung 840 PRO or EVO SSD running in RAPID mode is 2x, 3x or more times faster than without RAPID mode during the user's daily work. The user may not even realize the performance boost initiated by the RAPID mode.

I was almost ready to buy two.

got my best AS SSD Score with the new drivers and OROM!

@ domi1711:
Thanks for posting the previously missing details.

Although, when i look in the Device Manager under Drive COntrollers/ Driver details, it says 13.0.8.xxxx
Could you post a picture of your AHCI/Raid driver Details please?

Since I have done yesterday a complete reset of my Z97 AHCI system, I took the opportunity today to do some new benchmark tests with the newest available AHCI drivers.


EDIT:
Meanwhile I have put the results into the completely updated start post of this thread.

@ all Intel AHCI/RAID users:
To make it easier for you to compare the performance of the different Intel AHCI and RAID drivers, I have put the most important benchmark results I got with my Z68, Z77 and Z97 system into the start post of this thread.

Complete Update of the Start Post

Changelog:

• brandnew: latest benchmark results with my freshly rebuilt Z97 AHCI system (tests done at 09/07/2014)
• added: benchmark results with my formerly used Z68 RAID0 system (tests done in April 2014)
• added: benchmark results with my Z97 RAID0 system (tests done in July/August 2014)
• removed: benchmark results with my Z77 AHCI system running in RAPID mode (just to shrink the volume of the start post)

Because there are new Intel RST(e) drivers v13.5.0.1056 available since yesterday. I have done some benchmark comparison tests using a Tablet with an Intel 8-Series Chipset and running Windows 8.1 x64 in AHCI mode.

These were the 4 AHCI drivers I have tested:

• on-board MS AHCI driver named STORAHCI.SYS dated 08/22/2013
• Intel RST(e) driver v13.1.0.1058 WHQL dated 05/28/2014
• Intel RST(e) driver v13.2.4.1000 WHQL dated 08/04/2014
• Intel RST(e) driver v13.5.0.1056 WHQL dated 10/09/2014

• All 4 AHCI drivers gave my system a good performance.
• As expected for a comparson of different AHCI drivers, the benchmark result differences are visible, but not really noticeable while working.
• The performance of the generic Win8.1 MS AHCI driver is good and the Reading scores even better than those of the Intel RST(e) driver v13.1.0.1058.
• The Intel RST(e) driver v13.2.4.1000 gave my Tablet the best overall scores.
• Although the development of the v13.5 branch is still at the beginning, the new Intel RST(e) driver v13.5.0.1056 was nearly as performant as the v13.2.4.1000.

Thanks for the update. Any chance to have RAID benchmark comparison tests?
