160MB/sec is the maximum performance of the SCSI bus (not the hard drive). 19MB/sec is how fast the hard drive is going. The only time you're going to get something like 160MB/sec is with a bunch of Seagate X15s in a big RAID 5 config. Don't worry, you're okay. :) Nick mjj55409 at yahoo.com, on 10/05/2000 03:56:52 PM To: tclug-list at mn-linux.org @ PMDF cc: Subject: [TCLUG:22248] Adaptec scsi performance I'm running Debian (kernal 2.2.17) on a server at home: PIII 700 256MB ram with an Adaptec 29160 SCSI controller and an IBM ultra 160 hard drive. When I run hdparm -Tt /dev/sda, it reports: Timing buffer-cache reads: ...= 128 MB/sec Timing buffered disk reads: ...= 19.05 MB/sec I'm not expecting max performance, but 19 MB/sec is a helluva lot slower than 160 MB/sec. Anyone have any thoughts on this? mj __________________________________________________ Do You Yahoo!? Yahoo!
