The EZ-Dock 2 marks a natural progression for Kingwin's line of external hard drive docking stations, continuing support for 2½" and/or 3½" drives of either SATA I or II format, and now offering TWO bays to attach drives in. The unit can be configured using either JBOD or BIG to allow independent or combined access to the drive volume(s), and the end user is not limited to having two drives of the same size or type. The thick, wide base greatly reduces the likelihood of an accidental tip-over and the slot guides ensure proper alignment of the drives so as to avoid potentially damaging the SATA connectors when inserting or removing the smaller drives.
Unfortunately Kingwin did not follow suit with some of the original EZ-Dock's features, such as offering eSATA connectivity or the one-touch backup, and although the manual lists options for various other RAID levels such as mirroring and striping, these do not appear to be supported on this particular model. Given the existence of the eSATA-shaped knockout on the rear of the EZ-Dock 2 base, it's possible they plan to offer these expanded features on future models. But the eSATA connection in particular is sorely missed when transferring large chunks of data to or from the drives.
The Kingwin EZ-Dock 2 can be found online for around $40-$50, or less than double the cost of the original EZ-Dock. The price is kept low no doubt in part to the lack of an eSATA or RAID controller, while offering the potential for twice the capacity of the previous unit. Of course, you still have to figure in the cost of the drives, however with the ease of which these can be added and swapped around, starting out with one drive and upgrading later as capacity is needed would be a snap.
