While it does look very nice, it's worth remembering that aluminium is not well known for its resilience and prone to scratching. To counter that the enclosure comes with a carrying pouch made from plastic with a velvety-textured outer coating. Importantly this will also protect the enclosure from stray liquids - an important point given the perforated top which is just begging to have a mug of coffee spilled into it.
Everything considered the Jazz is probably one of the best enclosures I've seen to date, the build quality is admirable. Admittedly there isn't anything in the package that you wouldn't think would be there, but neither is anything missing that you would expect.
Performance is definitely acceptable as well. I tested using my usual mix of a single large file, namely Vista Service Pack 1 x64 weighing in at 726MB, and a folder containing a mix of Word documents and images amounting to about 60MB - repeated three times and averaged.
Vista SP1 transferred from the drive in 22 seconds, for a transfer speed of 33MB/s and was written to it in 26 seconds, at a speed of 27.9MB/s. The multiple small file tests showed similar figures of 31.5MB/s read and 26.7MB/s write. This is as good as any drive connected via mini-USB will offer so definitely not anything to complain about.
Despite not having any extra features on top of the obvious one of working as a USB drive, you surely won't expect me to call the Jazz expensive at around £12 - even if it is just a chunk of metal and a SATA controller. Well that's exactly the case, because while I can't say Enermax is offering a lot for the price, I still feel that given the build quality you are getting your money's worth - and then some.
Unlike many rival manufactures Enermax is making its place in the hard drive enclosure market not by trying to reinvent the wheel, but by offering a very good example at a great price. The only addition I'd like to see is e-SATA, but that really is the only complaint I have of the Jazz - and even then I'm scraping the bottom of the proverbial barrel.
