    Default Intel Rapid Storage Technology 11.05.0.1027 AHCI/RAID

    Looks like Intel has two versions of IRST starting with the latest release 7/24/2012. I am not using Raid but should I install the Raid version anyway and get AHCI for "free"? What am I missing? Can somebody shed some light on why Intel has gone to two versions?

    the IRST is not necessary if your HDD is in non-RAID mode

    Hyper is incorrect. I would suggest installing the latest drivers as by default windows will use MSAHCI driver, Microsoft's version. When you install the IRST drivers it will install Intel's version of the AHCI driver which should be better then Microsoft's version.

    I am going to take a guess that because the driver now appears to support both Windows 7 & Windows 8 that Intel put two listings. Since there is no listing menu yet for Windows 8, you get both under Windows 7. I downloaded both versions of the file STOR_Win7_8_11.5.0.1207_PV and did a file compare and they are identical.

    Kanon,

    I'm lazy and must be over-thinking the situation. Thanks for verifying that the two are identical. Intel must be just trying to confuse me.

    Yes you need the latest raid rom and drivers. See Raid0 and TRIM Support on Intel 11.5 OROM and Latest v11.5.0.1184 RST Drivers ?. I believe with the 1184 driver Trim was only working in Win8. They may have gotten it to work in win7 but not sure.

    Intel has does this with other drivers. They have also changed the whole version number scheme before for the driver and come to find out it was still the same driver.

    Ken429: IIWY I would avoid this particular build of IRST. Personal experience with 11.5.0.1207 is that the IaStorDataMgrSvc.exe service has a memory leak in it - on Windows 7 x64 at least. Found it using over 300MB t'other night - after which I went back to 11.2.0.1006. Have seen other people reporting similar in other forums too. Unlike Intel to let something like that into a release build. If anyone else is using it, have a look at the process in Task Manager to see how much memory it's grabbing. From what I recall it starts off normal then pulls a few more kilobytes each second - which starts to add up after a few days' uptime.

    Citizen Crazed,
    Thanks for the information. I'll stick with 11.1.0.1006 until the all clear sign goes up.
