    Unable to configure SSD cache on new Lenovo Y500

    Steve Koehler

      Hi, I just recently purchased a Lenovo Y500 Ideapad laptop, which is supposed to allow me to use the Intel Rapid Storage Technology feature to enable caching on a 16GB mSata drive that it comes with.


      I followed these instructions (note there is not option for RAID in the BIOS, just AHCI):





      These are the drivers I used when loading Win8 setup disk and the IRST utility used to configure within Windows:





      During the Windows 8 installation process, I was able to load the drivers with no issue. However once install was complete, and I installed the IRST util, it does not offer me an "Accelerate" button to configure the drive cache. When I called Lenovo support about this, after being on hold on and off for almost an hour, they looked up tech specs and informed me the chipset allows for the SSD caching with no software intervention....in other words the hardware "automatically takes care of everything." I'm struggling to believe them on this statement.




      Then, in reading the IRST install notes from Intel, I discovered a note stating the chipset driver needed to be installed first. So I uninstalled IRST, rebooted, installed chipset driver from Lenovo drivers page, rebooted, then reinstalled IRST, and rebooted. Still no "Accelerate" button. Also per some of the comments in the IRST install readme, I see under "IDE ATA/ATAPI controllers" a device named "Intel(R) 7 Series Chipset Family SATA AHCI Controller" which uses a driver called iaStorA.sys version from Intel.




      If it makes any difference, in Windows disk management I see my 16GB mSata (drive 0) with a 350MB NTFS partition, and the rest unallocated. The main 1TB drive (drive 1) is C: and the entire thing is one NTFS partition.




      Can anyone confirm if I should be seeing an accelerate button in IRST, or how I can tell is drive caching is happening? Any help would be greatly appreciated....this is driving me insane!!




      Included below is the system report from IRST showing config details:
