I bought a 16GB SSD from MyDigitalDiscount.com.
I purchased this one:
43mb/s read and a 26mb/s write. (sustained) with a 45/41 burst.
This makes it MUCH faster than the stock 16gb card my box came with (and that card is now for sale if anyone is interested).
According to jkkmobile, the stock card measures at 32/13. I can feel the speed. The OS installed in less than 1/2 the time.
Everything else seems a little snappier. I need to get a 2gb ram chip sometime soon, but this is a noticeable improvement in feel. I still geekbench at about the same at 901-ish.
