-Long USB 3.0 cable, much better than any other dock provides
-Fast transfer speeds, about 60-90 MB/s constant write speeds
-Both drives work out of the box, no need for a firmware update
-LED activity light
-HDD sleeves are perfect accessories
Weaknesses:
-Two drives show unpartitioned space, even though it never exists
-The LED can be annoying in the dark
-A little too expensive compared to its competition
Summary:
Bought it as a replacement for my Vantec Superspeed dock, and liking it much better. The only concern is about the unpartitioned space that shows up when two hard drives are being used, but it works without any problems.
