I have the 500GB version, and I love the drive! I ran some quick tests Using Sisoftware's Sandra.
The disk can pull 140 MB/sec sequential read, and at the end of the platter it still reaches >75MB/sec. Will post the data later at home.
Like most of the ATers, I have enough storage to host my own pron website

Among the drives I got are a Seagate 7200.10 (320 GB), a WD caviar green EADS (1 TB), a Samsung Ecogreen F2 (1 TB), WD AAKS blue (2 x 500 GB) and a Hitacki Travelstar 7K1000.B
Sandra shows the WD blue and the 7200.10 topping at aprox 85 MB/sec max, the WD green at aprox 95 MB/sec max, the ecogreen F2 at aprox 110 MB/sec max and the 7K1000.B at aprox 110 MB/sec max. In real usage, the green drives do indeed perform slower, and feel sluggish. The 7K1000.B is noticeably faster than the rest of the drives except the F3, and the F3 is noticeably faster than the 7K1000.B
If you add the fact that the drive is almost silent, this is a winner!
