I can't speak for WHS, but I have the single version Black X, not the Duette. I love it and have had no problems with it. Mine is USB/eSATA. I use the eSATA and it works very well.
+1 for the Thermaltake BlacX. I have the single version of both the USB/eSATA dock and the USB 3 dock. The USB 3 dock is backward compatible with USB 2 and both docks support either 2.5 or 3.5 HDD's.
