Ditto. A while back I played with a 7200 RPM Seagate ST15150N and a narrow DCAS 34330 on an SGI Indy R5000. Simple test using dd to write a 1G file in 1M chunks yeilded about 8M/sec for the IBM and 7M/sec for the "faster" Seagate. Both disks had freshly created XFS filesystems. The Indy SCSI was only Fast, not Ultra. I don't think rotation speed tells the whole story. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
