For the PATA drives, I used hdparm -tT /dev/hda to get the numbers. The sdparm utility does not seem to have a testing mode. Here are the details of my drive: # sdparm --inquiry /dev/sda /dev/sda: ATA ST3250310AS 3.AA Device identification VPD page: Addressed logical unit: designator type: vendor specific [0x0], code set: ASCII 00 20 20 20 20 20 20 20 20 20 20 20 20 39 52 59 30 9RY0 10 33 36 59 57 36YW designator type: T10 vendor identification, code set: ASCII vendor id: ATA vendor specific: ST3250310AS 9RY036YW I tried the hdparm on my sata disk and got these figures. # hdparm -tT /dev/sda /dev/sda: Timing cached reads: 1498 MB in 2.00 seconds = 749.55 MB/sec Timing buffered disk reads: 244 MB in 3.01 seconds = 81.06 MB/sec Regards, -- Sridhar M.A. GPG KeyID : F6A35935 Fingerprint: D172 22C4 7CDC D9CD 62B5 55C1 2A69 D5D8 F6A3 5935 Money cannot buy love, nor even friendship.
