Simpletech Duo Pro External Dual Drive Enclosure?

[Zarathustra[H]]

Has anyone used one of these?

Are they any good?

Looks like you just pop two matching drives in there, set the switch to striping or mirroring and off you go.

Sounds like it could be a great backup solution, especially with its eSATA connector.

Anyone have any experience?

Also, this looks suspiciously similar to Hitatchi's Duo Pro drive. Is it just an unbranded enclosure without the drives?
