Kitty - I'm not 100% sure - It's supposed to - but I still use Diskpart and manually set an offset of 128 to make sure. Then I install Win 7. But Win 7 should detect an SSD and should align accordingly. I've always understood stutter to be caused almost exclusively by alignment, although I do have an old Gen 1 JMicron-controlled SSD on a Vista system, and it stutters about 5% as much as a Gen 2 drive with 64MB RAM cache, unaligned, on XP Pro. So at least in my experience you are correct about using the term exclusively. It can still happen. It virtually NEVER happens on my Vertex Win 7 system, and I've NEVER had it happen on a Corsair P64 Samsung-controller based system on another Win 7 computer, and that one was a direct clone of an XP system, so I'm about 99% sure it is NOT aligned correctly. I was in a pinch and had to just port the image over and I've never clean installed the P64.
I've always understood drive geometry alignment as the primary cause of stutter. I aligned an old SLC Gen 1 drive on XP Pro on a SuperMicro board from offset 63 to offset 64 using diskpar (NOT diskpart on XP systems). You never saw a system fly so fast, and that SLC drive had zero onboard cache.
Just FWIW's and of course your actual mileage may vary.
