How do I actually update the driver for this? I have win 8.1 and task manager says IAStorSataSvc (32 bit) (intel rapid storage technology) is using 277.8 MB of memory (it was over 1,000 last night) and .4% of the CPU. My version is 11.50.1207 and forums indicate this version eats a lot of memory and the driver should be updated. How do I do that? There are two versions that can be downloaded, f6flpy-x86.zip - for 32-bit versions of the operating system and f6flpy-x64.zip - for 64-bit versions of the operating system. Win 8.1 is 64 bit and the IRST says it is 32 bit, so which one do I use? Once I have the right one dowloaded, it is a zip folder with 6 files. How do i update the driver, double click on one of the .sys files, the largest one (there are two, one smaller than the other)?
