Pros: This unit was nonfunctional in USB 3.0 mode on arrival. I have several other USB 3.0 enclosures, so it was not hard to confirm that it was defective. It did perform normally as a USB 2.0 unit, and the USB 3.0 cable which was included was functional, so I decided to keep it rather than pay the RMA shipping.

Cons: Poorly designed, difficult to insert a drive unless the light cable is placed exactly correct from the front to the back of the unit, and (of course) it was defective on arrival, working only as a USB 2.0 unit.

Overall Review: The Kingwin USB 3.0 enclosure is much better designed and about 40% less expensive. I would therefore recommend against purchasing this Zalman unit.

Pros: It does store 14.7 GB of data

Cons: Patriot should be ashamed to label this as a USB 3 drive ! When I began to use it, it seemed to be slow, so I did some tests. First, after formatting all of the drives used in this comparison, I transferred a folder of 2.24 GB containing 2400 JPEGs from a fast Windows 7 desktop computer to each of the drives. For this Patriot USB 3 flash drive, it took 3.8 minutes (or less than 10 MBs). For two different USB 2 SSDs, it took 1.5 minutes. For a standard USB 3 hard drive, it took 0.4 minutes. I wonder if most USB 3 flash drives perform this poorly due to their general design, but for Patriot to advertise that the read speed of this drive is up to 90 MBs is extremely misleading, perhaps bordering on false advertising. I would ask that other folks do similar tests on other USB flash drives and post the results like this in reviews.

Overall Review: If you want a fast drive, don't buy this one.

Pros: Inexpensive

Cons: I have purchased four of these SSDs over the last two years, and two appeared to be dead on arrival (but weren't). Using any one of several external enclosures, on any of several computers, they would not even show up in Disc Management. Yes, they need to be initialized, partitioned and formatted, but that can't be done if they don't show up. In desperation, I hooked one up as an internal drive and it worked normally. I initialized, partitioned and formatted it, then removed it and put it in any one of several external enclosures. Again, it would not show up on any of several computers. Then I tried plugging in one of the enclosures' auxillary USB power cables (designed for regular hard drives), followed the normal USB connector, and "voila" the SSD worked normally !

Overall Review: Apparently, some of these units are not adequately powered using a single USB connector. When used as an internal drive, this defect is not a problem, but it is very irritating when using this as an external drive. I have never had this happen with any of the other SSD drives that I own which are made by OCZ or Crucial. There is really no excuse for a SSD to need additional power beyond the standard USB connection, thus my rating of "3". I will probably not buy any more Kingston SSDs in the future.
