Not quite true. The *ONLY* *TRUE* hardware IDE RAID: http://www.3ware.com When they do comparisons against other RAID manufacturers, they compare to SCSI RAID, because the other "IDE RAID" manufacturers simply do not even come close. If you are using HighPoint or Promise or any of those other "IDE RAID" chipsets, you are *NOT* using hardware RAID, no matter what they claim. Having said that, Adaptec seems to have a card that is similar to the 3Ware card, but I've no experience with it. >SCSI is very well supported because >it does not rely upon device drivers.

I think that it always was in relation to the cost of losing the data. eg, the disk is less expensive than the data. I just made that up, but it sounded good. -- /g "Outside of a dog, a man's best friend is a book, inside a dog it's too dark to read" -Groucho Marx Want to buy your Pack or Services from MandrakeSoft?

AFAIK, SCSI RAID has been around for eons. I think first used it on a Novell 3.12 server back in 1993 or something like that. The machine was a compaq P90 server with a smart array controller. 3-4.3 GB hard drives gave us 8.5 GB of usable spce, which was wyy more that we could have ever imagined using. -- /g "Outside of a dog, a man's best friend is a book, inside a dog it's too dark to read" -Groucho Marx Want to buy your Pack or Services from MandrakeSoft?

Originally (as per the Berkeley geekz), RAID stood for Redundant Array of Inexpensive Disks. However, it's now more commonly defined as Redundant Array of Independent Disks. Prolly because SCSI is used more often, and they ain't "inexpensive" ;-) -- HaywireMac ++ ICQ # 279518458 Registered Linux user #282046 Homepage: www.orderinchaos.org ++ Mandrake HowTo's & More: http://twiki.mdklinuxfaq.org ++ You can't take it with you -- especially when crossing a state line.

It requires three disks though. It allows for one disk to be removed on failure, a new disk to be installed, and the data to be rebuilt from the other two disks. Excellent for mission critical stuff. The data effectively gets written 1.5 times across the three disks. No hardware RAID (on i586 architechture) supports this to my knowledge, but then it was attested that linux software raid was always better anyway:) -- Michael Want to buy your Pack or Services from MandrakeSoft?
