If performance or throughput is an issue though, be careful what you pick out for external drives. USB stinks for data transfer. FireWire 400 is OK. FireWire 800 is better. Best though, eSata. Some of the newer laptops/desktops have an external eSata port.Originally Posted by uscwest, post: 245179
Rather than spending money on external drives, where you pay extra for a fancy enclosure and power supply, I bought a drive dock:
NewerTech Voyager Q- Quad Interface SATA 2.... (FWU2ES2HDK) at OWC
This allows you to buy standard eSata internal disks for external use. A 1TB internal drive is a fraction of the cost of a decent 1TB external drive. And, you don't need the fancy power supply or case. I bought the drive dock and 2 x 1TB eSata drives for under $200 after Christmas to add to my redundant backup arsenal (I shoot about 300-400GB per year digitally).
The nice thing with this particular dock is it supports USB2.0/FW400/FW800 and eSata. So, I bought an eSata card for my desktop to ensure fastest possible data transfer speeds.
