Mine responds with: #hdparm -Tt /dev/hda /dev/hda: Timing buffer-cache reads: 128 MB in 0.78 seconds =164.10 MB/sec Timing buffered disk reads: 64 MB in 3.33 seconds = 19.22 MB/sec # hdparm -Tt /dev/hdb /dev/hdb: Timing buffer-cache reads: 128 MB in 0.32 seconds =400.00 MB/sec Timing buffered disk reads: 64 MB in 1.42 seconds = 45.07 MB/sec
