If you are going to be spending money for multiple discs to create an array, you have decided that cost is reduced in importance compared to either performance or reliability or both. If you need to purchase a special card anyway (I haven't looked at the price of this IDE setup), it seems to me that cost becomes a much smaller factor. You double or quadruple your disc cost in either case. You buy a marginally cheaper interface card but take a performance hit with IDE compared to SCSI. SCSI is much more flexible with the number of discs connected, not to mention the ability to add a tape that can handle your needs in throughput and capacity. (RAID is not substitute for backups, IMHO.) The cost of even a moderately pricey server ($4,000) is small change for any business with at least two employees who are not the propreitor's brothers-in-law. One could get SCSI with RAID in a box for under $2,500 by my guesstimation that could handle any small LAN and its users. I don't see much benefit in this. Maybe you save a couple hundred bucks or ten percent on your server with some detracting issues? This sounds like a solution looking for a problem, as I have heard it said recently. This is merely my $.02. Thank you, Jason C. Wells To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
