@Sky87:
If the "Add/Remove Software" list of the Control Panel doesn't contain any "Intel(R) Rapid Storage Technology", the related Software is currently not installed. So in this case nothing has to be uninstalled from within the Control Panel.
But if the Intel RST Software is listed within the "Add/remove Software" section, it has to be uninstalled, before the user is going to install any other Intel RST driver (no matter, whether as "pure" driver or as "Drivers & Software Set").

Yes, i understand. I am a bit confused about the difference between RST and RSTe, does it matter which one of these i install? From my understanding, RSTe contains iaStorA.sys and iaStorF.sys. My current AHCI controller currently has just one driver listed, which is iaStorA.sys.

Therefore i am unsure if i should later try the v13.2.8.1002 RSTe package if the default Windows SATA driver proves to not work well.

I also would like to know what this driver is used for, as i do not use a RAID setup. What happens if i disable the C220 SATA AHCI Controller from Device Manager?

@panosxidis:
Look into the start post of this thread, find it out yourself or ask our Forum member 100PIER, who has an Intel X99 chipset system.

@panosxidis:
I gave you already the answer to your question (see above).
That is why I have moved your post here.

#728 RE: Intel RST/RSTe Drivers (newest: v17.0.0.1063/v5.5.0.1334 WHQL) by Kirill 03.01.2019 22:44

Hello to everyone!

I want to know, which versions of Intel AHCI/RAID drivers and Intel Rapid Storage Technology (if any) are suited best for my system, if I'm going to make a clean installation of last edition of Windows 10.
I read carefully first three posts in this topic and many other information on this site including first post here (Which are the "best" Intel AHCI/RAID drivers?) and first and second posts here (Performance of the Intel RST/RSTe AHCI/RAID Drivers)
Also I read information about this theme on other sites (including intel.com). But I'm not a very advanced user of PC, and maybe because of that I didn't understand once and for all every aspects and nuances of this and other relevant software (Intel Chipset Device Software and Intel Management Engine Interface).

Hardware:
- Chipset: Z97
- Mainboard: Asus Z97-K (version of BIOS: 2902)
- CPU: Intel i7-4790K
- HDD: Toshiba DT01ACA100
- Videocard: Nvidia GeForce

I have these variants for AHCI/RAID drivers:
01) Asus download center: 14.5.0.1081
02) Intel download center: 14.8.16.1063 (but it tells that version "16.8.0.1000" is newer)
03) This site:
14.8.18.1066 (in this topic)
13.2.8.1002 (Which are the "best" Intel AHCI/RAID drivers?)
16.7.9.1027 (second place) (Performance of the Intel RST/RSTe AHCI/RAID Drivers)

If version "16.7.9.1027" is on second place, that means, that newer versions are suited for my system too. Although in descriptions for these versions on Intel's site I didn't see my chipset and CPU.

So now I am a little confused (already a third time), which version I need and (more importantly) which version is actually best. This site offers at least three suitable variants, Intel offers two variants and also Intel tells that for this kind of software version of a vendor is more suitable, which means that version of Asus is better.

And one more thing: since I have just one HDD and haven't any other HDDs or SSDs, I thought that I need only SATA/AHCI drivers (and relevant option in BIOS), but I found information, that Intel recommends RAID-mode even in those cases, when user have just one disk drive and don't want a RAID-massive.
Now I am confused a little more. )

I will appreciate any kind of help.

Thanks!
Kirill

@Kirill:
Since each system is somehow different, the user has to find out him-/herself, which is the best storage driver for his/her specific system.
You are lucky, because I have recently (1 month ago) compared the performance of many different AHCI drivers on a system like yours (Z97) running Win10 x64 v1809. >Here< you can see the test results. The clear winner was the Intel RST(e) driver v13.2.4.1002.
Unless you have created or want to create a RAID array, I recommend to set the on-board Intel SATA Controller to "AHCI" and not to "RAID" mode.

@Fernando, thanks for reply!

If only I knew, what parameters of working system I should watch in order to see differences between versions of drivers... )

But I found out that my system is booting faster with these drivers than with drivers pre installed by Windows.

When I did an installations of Windows before, I didn't install SATA AHCI drivers every time. Because I didn't know exactly for what these drivers are and also I've seen that system already had these drivers. After some installations I noticed that my system is booting faster (approximately 19-20 seconds according to Task Manager) comparing to the other ones (from 31 seconds and up). And only now I discovered that that is because of these drivers.

Anyway, Fernando, please tell me how difficult to you to do those tests with these drivers in terms of time and your occupation?

The preparation and execution of my recent benchmark tests inclusive the related documention took me some hours of my free time. By the way - I am a retired Veterinary Surgeon.

EDIT: I have moved your request and my answers into this better matching thread.

That's a good profession.

Ok. So, if I will ask you to do those tests on Z97 platform one more time, but with another set of drivers (6 different versions), will it be a huge burden for you?

Since I have given away my Z97 system at Christmas, I cannot do any additional benchmark tests with it.
My questions:
1. Which 6 driver versions are more interesting for you than the 7 I had tested in November 2018?
2. Why don't you do the tests yourself?

#734 RE: Which are the "best" Intel AHCI/RAID drivers? by Kirill 07.01.2019 19:26

@Fernando

1. Sorry, 7, not 6. And two of these seven versions are from your previous tests. But because I don't know how exactly you do your tests, I presumed that these 2 versions (which you already tested and which I'm interesting in) can show another results, if test will be done in conjunction with the another 5 versions. These versions are:
- 13.6.0.1002 (from Intel)
- 14.0.0.1143 (from Intel)
- 14.5.0.1081 (from Asus)
- 14.6.5.1036 (from this site)
- 14.8.0.1042 (from Intel)
- 14.8.16.1063 (from Intel)
- 14.8.18.1066 (from this site)

2. Because I don't know how exactly these tests need to be executed. And even if I will found some manuals or instructions, since I always want to know every detail, it will take a lot of time for me. To learn about those tests, how they are working, what environment is required and so on. And I'm already pretty tired. Because I decided to reinstall Windows about 20th of december. And I reinstalled it. But this time I decided to dive deeper than usually to learn more about required drivers. And now I regret about it. Because now 7th of january and I still stuck. All that I'm doing all this time is searching-reading-searching-reading. That's it. )

@Kirill:
Here are my comments to your driver favorites:

Zitat von Kirill im Beitrag #733
- 13.6.0.1002
If you want to test an Intel RST driver from the v13.6 branch, you should better choose the v13.6.3.1001, which is the latest from that branch. By the way: The latest from the v13 platform is the driver v13.2.8.1002.
Zitat von Kirill im Beitrag #733
- 14.0.0.1143
This was the first WHQL certified driver from the v14 platform. The later released v14 platform drivers are better.
Zitat von Kirill im Beitrag #733
- 14.5.0.1081
The newer and probably better driver from the v14.5 development branch is v14.5.2.1088, but according to my own tests the v14.5 series drivers don't have a good performance.
Zitat von Kirill im Beitrag #733
- 14.8.0.1042/14.8.16.1063/14.8.18.1066
The latest (best developed) Intel RST driver from the v14.8 branch is v14.8.18.1066, which was 1 of my test candidates in November 2018.

Happy testing!
