Just ran this to see how my new SSD is, and doesn't look to good compared to others, as you can see here :- Notice it also says pciide - BAD for some reason. Now, i thought i was already running my HDD (which i just cloned across to save me reinstalling everything) in AHCI mode, so no need to change, but ive checked my BIOS, and nope, its in IDE mode, so would i benefit from switching it to AHCI as per the sticky ? Sticky :- http://forums.guru3d.com/showthread.php?t=313676 My WEI rates it as a 7.0 (HDD was 5.9), and my Windows only takes 30 seconds to load up with everything, instead of over a minute via the HDD, and it does seem faster compared to my HDD, but im probably missing out on a lot more speed. Thanks. EDIT: Actually, i remember now, a few months ago i had crashing problems (which are all sorted now), and after one crash, my BIOS had reset, so i had to set it all back up, but obviously, i forgot to redo the IDE to ACHI If i did the switch to AHCI via the sticky, would i hose it all, as a couple of people in there have said they've done it, but now can't boot either way ?
