ICY DOCK MB664US-1S: eSATA with a twist

Conclusion

We previously reviewed the MB664's less-expensive sibling, the MB559, and our performance results here are virtually identical. Indeed, the MB664 seems to share the same PCB components (albeit arranged in a slightly different configuration) with the MB559, so this was largely an expected result.

Where the two products differ is in the packaging, the PC adapter which is included with the products, and in the treatment of the hard drive itself. The MB664's "tool-less" installation of the drive works flawlessly, and (unlike the 559) there is no need to remove a caddy to install the hard drive. In our tests, installation was relatively straightforward, though we did find ourselves checking from time to time to make sure that the drive's connector was seated properly in the PCB. (There was never an issue with this - the uncertainty was simply because the PCB is completely hidden by the drive the moment it is put into the enclosure).

The addition of a power socket on the back of the PC adapter is interesting, though we do wonder how often it will really be used. A big part of the attraction of an external enclosure like this, after all, is portability - if you only have the power cord for the PC adapter, then the enclosure is restricted to that unit (even with USB). Nevertheless, it's clear that there are uses for the MB664 that go beyond simple portability, and the ability to not occupy another wall socket is a welcome one.

The fit and finish of the MB664 is nearly flawless. Everything fits together perfectly and feels very secure, without any flimsy bits. ICY DOCK has designed their MB664 (like the MB559) extremely well. On the negative side, the MB664 could do with a more secure stand. The scissor-style feet hold the unit properly, though larger feet could have provided more stability. Equally, while the front panel on the MB664 is adequate for the job, a more satisfying "click" during closure (or, conversely, a more energetic response when the unit is opened) would be welcome.


The street price for the MB664 hovers around $70 and is available both in the silver aluminum finish, or a glossy black (similar to the one in our MB559 article). For the $15 premium attached to the MB664 compared to the MB559, the user gets the aforementioned option to draw power from a PC power supply, as well as the simpler hard drive installation. For most users, we believe the MB664 is the way to go on the strength of its slightly-more-secure hard drive installation, though in truth both products are exceptional offerings at their respective price points.
