I use RAID 5 on an 8 port 3ware card with 7 active 60GB IBM disks. It's really slow at a max write speed of about 7MB/s for any block size. I've had read speeds at about 16MB/s. The box is a PIII 450 with 512MB RAM KEN On Wed, 13 Feb 2002, Mike Tancsa wrote: > At 04:30 PM 2/13/2002 -0800, Bill Swingle wrote: > >Does FreeBSD support Raid5 on the 4 port 3ware card?
