I've got socket 939 AMD Athlon 64 X2 4200+, nForce4 board, 2 GB RAM in dual channel, hdparm -tT on 74 GB Raptor (WD740GD-00FL Rev: 31.0) says: # hdparm -tT /dev/sda /dev/sda: Timing cached reads: 1942 MB in 2.00 seconds = 971.33 MB/sec Timing buffered disk reads: 202 MB in 3.02 seconds = 66.97 MB/sec Looks like the rest of you.
