5 out of 5 eggsit is very fast

Pros: very fast, this is from NTI Analyzer:
ill) SAMSUNG HD103SJ USB Device
97.33 MB/S
187.50 MB/S
83.08 MB/S
187.50 MB/S

Cons: small con. there is no instruction sheet and you can't download one from their site(404 error)
there are two countersink tabs to make the drive snug in the case. but the screws are pan head. I fiddled and found an orientation that worked, but a sketch on the box would have been nice.

Other Thoughts: it is only 4.17 times as fast as my USB 2.0 enclosure was but it is 1.5 times as fast as my external USB 3.0 drive...which is powered by the USB port instead of plugged in.
anyway, I will buy another for my other drive I use as an external for porting data. nice improvement in my life

5 out of 5 eggsworks well so far

Pros: The enclosure has some vents to let heat escape, but it doesn't have active cooling. The case is made of aluminum which I hope acts as a heatsink for the hard drive. Comes with a USB cable!

Cons: Not really a con, but since this item doesn't have a fan, I would suggest pairing it with a low-temperature drive like the Western Digital Green series. Those WD Green drives operate at a lower rotational speed, but that's OK in this application because your bottleneck will be the USB interface and not the drive's specs.

Other Thoughts: I got the impression from the picture that the case was a woodgrain design, but in fact it looks like copper. In any case the appearance of the item doesn't matter because it's installed in the server room where no one ever sees it.
