Concur with Pyree comment on disabling restore point, or at least limiting the number of (more on this at end of post). In reference to AHCI, good catch.
However for Intel systems
.. (1) You can use either AHCI or Raid in bios. The only cavet is do not use the SSD as a member of a raid0 or 1 setup.
.. (2) After installation, make sure you update, or install, the latest Intel RST driver (10.6)
.. (3) On newer MB, if you have a choice between on board marvel controller and Intel - USE INTEL
.. (4) You can verify driver and alignment by downloading and running AS SSD (Do NOT need to run the Benchmark). Upper left will indicate the driver (for Intel chipset MB driver should be iaSTor, Better performance than default msachi. Will also show a green OK. Aginment should also show a green OK.
Back to my "at end of". Windows 7 has an excellent backup program (new to Win7) that allows you to create an image file of your "C" drive and put it on a 2nd internal HDD, an External HDD (best option), or on DVDs. When it completes the image it will ask you if you want to create a bootable Restore DVD, If you have a windows Installation disk (Gee how did you install window) you need not create - just use the install disk and select repair. Highly recommend you do this, only need to recreate image periodically, not as often as regular sched BU of your data. This image will restore windows and all programs with out having to re-install windows 7 and ALL of your programs. (about 10 Min to recover from a HDD failure (not counting putting in a new HDD LOL)
Buy the SSD and ENJOY!!!
