I imagine the new machine will have a fairly recent firmware for the card which matters in my experience. RAID 5 on the card is OK, but if you want speed, I found mirrored RAID 0 is a fair bit faster. Also, note the defaults used when making the stripe set. Depending on your situation, its not necessarily what you want. There was a time when the card would give grief under high disk load, but this appears to have been fixed now. ---Mike -------------------------------------------------------------------- Mike Tancsa, tel +1 519 651 3400 Network Administration, mike@sentex.net Sentex Communications www.sentex.net Cambridge, Ontario Canada www.sentex.net/mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
