Years ago, before I installed my new narrow DCAS on a FreeBSD system I tried it first on an SGI Indy R5000. With a fresh XFS filesystem on one each, DCAS (5400 RPM) and Seagate ST15150N (7200 RPM) the DCAS handily beat the Seagate on a: % time dd if=/dev/zero bs=1024k count=1024 of=file_on_disk Think the Seagate did just shy of 7MB/second when the DCAS did a tad over 8MB/minute. The Indy only had fast SCSI. -- 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.
