But do you?
All hardware-RAID solutions have had sundry problems -- and the Linux
kernel's software-RAID support has improved so dramatically (from early
days) that it's a very attractive option. The biggest argument against
that option (the kernel's md driver) is CPU loading, but Linux servers
almost always have ridiculously underused CPUs, anyway.
About the only ATA ("IDE") hardware-RAID controller I'd even consider is
3Ware's. The others are either incomplete (the drive-array equivalent
of winmodems) or require proprietary binary-only drivers, or both.
3Ware have at least one model that furnishes four separate ATA chains --
very helpful in order to avoid putting any two ATA hard drives on a
single chain, which cripples performance. But then, beware of heat
problems with all those ribbon cables snaking across the inside of your
case.
Why don't you prototype a system using the md (multiple device) driver,
and see if that meets your needs?
