Don't sweat the "no tape" recording.
Hard Drives are so cheap now. Just buy 500GB Seagate SATA drives from Amazon. $116.93 each.
Get the Weibetech drivedock:

And you have a cheap backup solution.
Thanks, Scott K.
I just ordered this. For me, I think this is a better unit since it has both USB 2.0 and eSATA and easier to use with a hard drive. There's no cable to fool around with. The big problem with this unit is the shipping. It takes one week to gather all the information before shipping, for whatever reason it is, then about two weeks to reach destination.
