Editor's note: this review has been updated. While we originally believed there to be an incompatibility between the RocketStor and HighPoint's RocketU 1144A, this is not the case; rather, the incompatibility lies between specific hard drives and the RocketU 1144A.
HighPoint doesn't do USB 3.0 by halves. When most vendors will happily do multiport USB 3.0 adapters but share all ports across a single controller chip, thereby reducing maximum simultaneous speed, HighPoint instead adds a single controller chip per port to squeeze the most out of the interface.
The same thinking goes in to its RocketStor, a 3.5- and 2.5-inch SATA to USB 3.0 dock. There are two bays, but each is fed by a dedicated USB 3.0 cable. Both of these cables are joined together into a single entity that's only about 1 metre long — so it won't necessarily suit all set-ups.
The unit itself is white-gloss plastic, and it looks and feels a little cheap. There's an eject button on the right-hand side that pushes drives up to help with release, although realistically you can just pull the drive right out. A "Snap Backup" button is on the top, which works in tandem with HighPoint's included software to automate backups. Interestingly, the software is run via a local web server on Apache, rather than providing native code.
The layout is incredibly confusing, and just to assign a backup task to the button on the device is a chore. Incremental backups can be performed, and are each stored as a compressed file with an index rather than just a straight copy, under the folder ".RocketStor". The latter isn't great — as a dot folder, it'll be hidden under OS X and Linux, which may make some neophyte users believe a drive is empty when it's not. You'll need to use HighPoint's software to recover whatever you may back up.
