Adaptec. IDE versions ATA1200A and ATA2400A (if I recall correctly). SCSI versions too. Mylex ExtremeRAID or DAC960 (older models). I've only used their products on SCSI drives. AMD(?) MegaRAID; SCSI.

RAID is not the same as off-site backups. It boosts performance or protects against failure of a single hard disk or both. To be able to hot swap drives and rebuild on the fly requires a drive enclosure/chassis and carriers that support such activities. It is frequently easier to buy it built into a server, such as Dell's Poweredge 1500SC, 2500, etc. If you want hot swap drive capability in an external enclosure, check out Dell, Compaq, IBM, and other. One third party that makes a nice (though expensive) external enclosure with redundant power supplies and hot swap is Kingston's Data Silo products.
