This 1.5TB Seagate ST31500541AS drive spins at 5900 rpm. Was your old drive a 7200 rpm model? If so, that would explain the performance drop. The old drive will probably be faster across the board with random I/O. The new drive will likely stream sequential I/O a bit faster. Given that the bulk of most workstation/desktop I/O is random, the drive with the faster spindle speed will have better performance, even if it is older. For example, as a test, slap a used U320 SCSI card and a 5 year old 73GB 15,000 rpm Seagate or IBM U320 SCSI disk into your current workstation and you'll see it run circles around _any_ brand new 750-2TB SATA drive. It'll be twice as fast or more with random I/O pretty much across the board, and will still be competitive WRT streaming I/O. When it comes to mechanical disk performance, there is no substitute for spindle speed. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
