Connecting multiple storage drives externally doesn't work equally well on every connection type. If you were to use a USB 3 connection you would get the speed necessary, but your access times would suffer. If you were to connect it via eSATA you would have the access times, but shared bandwidth between the connected drives.

The solution is a direct SAS connection and the SilverStone TS431S that I?m taking a closer look at today is just such.
