Why not buy a SATA drive and an external enclosure that provides both USB and eSATA interfaces? That way, you will know that if the drive fails (or you want a higher capacity), you can easily replace it. Be aware that a lot of dual interface enclosures only support USB 2.0. I'm still looking for a moderately-priced USB 3.0 / eSATA enclosure.
Edit: It may also be cheaper than buying an integrated unit.
