It looks like he compared the SSD to 80GB 7200rpm drives. Those are much older and slower than the current top of the line 320GB 7200rpm drives.
I'm not saying the low end SSDs are bad, just that they aren't the speed demons some think they are. I know in another thread you were disappointed by the speed of the 7200rpm driver versus the stock drive. If you are thinking the SSD will be faster, it's going to be a little faster on read and slower on write than the 7200rpm. The faster SSDs are noticeably faster than the 7200rpm and the slower SSDs. Depending on your expectations, you may or may not be happy with the slower SSDs in speed. If noise and vibration are the main factor, all the SSDs are silent and big improvements over the 7200rpm drive.
