1. Silicon Image SV2000

800GB, External SATA (PCI card included), Supports RAID 0, 1, 0+1, JBOD , Price when ranked: $2200

Bottom Line: The undisputed winner in our copy files (and folders) test and our system backup test, this flexible unit is aided by its external SATA connection. Too pricey to get our Best Buy, though.

2. WiebeTech Raidtech 800

800GB, USB 2.0, FireWire 800, FireWire 400, Supports RAID 0, 1, Price when ranked: $1400

Bottom Line: Its two 400GB drives striped together using RAID 0 provided very fast performance in our tests. But its lack of expansion and limited RAID options make it a bit pricey.

3. LaCie Biggest F800 1.6TB - 1600GB 4-Drive External Firewire 800 and USB 2.0 Hard Drive Array with Hot-Swappable Drives Cooling Fan

1.6TB, USB 2.0, FireWire 800, FireWire 400, RS-232 serial port, Supports RAID 0, 1, 5, 10, Price when ranked: $2200

Bottom Line: This device has massive capacity, all right--and the lowest cost-per-gigabyte in this category. But in our copy files test, it performed more like a network drive.
