But there are a number of factors that mitigate this. a) is the hardware on the card adequate. e.g. an old DAC-960 will not be as fast as vinum running on a P4. b) are the drivers any good c) how good is the software implementation of RAID. I posted to STABLE a while back comparing a couple of benchmarks that showed this not to always be the case. ---Mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
