The only fault with RAID 1 is that for each disk you want to mirror, you need a second one to mirror the first. Read performance is pretty good, but write performance isn't as good as RAID 0's write performance. RAID 5 can be overkill, but if you need really fast read access and have the money to go either SCSI, or use vinum for software RAID 5, you will need three hard drives minimum. // Linh Pham // http://closedsrc.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
