Thanks. Now I see that the 33MB/s speed limitation is not my fault. :) Then I can do exactly nothing to speed it up. --Guolin Cheng -----Original Message----- From: William Hooper [mailto:whooperhsd3@xxxxxxxxxxxxx] Sent: Friday, April 30, 2004 4:50 PM To: fedora-list@xxxxxxxxxx Subject: RE: disk problems or false alarm??

To very broadly generalize 33MB/s sustainable is a limitation of physically reading the disk, not the interface from the motherboard to the disk. All the ATA66, ATA100, and ATA133 specs are about burst speed (basically reading from the disk's on board cache). Alternatives for faster sustainable speeds would include: faster spinning SCSI disks, RAID, non-mechanical hard drives. -- William Hooper -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: http://www.redhat.com/mailman/listinfo/fedora-list
