1.0 out of 5 stars An extremely weak offering from a manufacturer that is usually rock-solid., 28 Mar 2013
Verified Purchase(What is this?)
This review is from: Kingston Technology DT111/16GB 16GB USB 3 Data Traveler 111 (Personal Computers)
While Kingston's DT111 line may have the hardware to be USB 3.0 compliant, what it does /not/ have is data rates anywhere near acceptable for a SuperSpeed USB device.

Reviews for the product here have been mixed. I can only imagine that the positives are paid. Every device in the DT111 lineup suffers from the same cripplingly abysmal write speed - unlisted by the manufacturer, and substantially less than typical for even a USB 2.0 device.

Below are crystalmark results for the 16GB stick under various configurations. SuperSpeed USB is being used for the transactions, as confirmed by the USB Implementers Forum test suite.

These tests were carried out on 2013/03/28, on the following (relevant) system configuration (and obviously with up-to-date drivers):
MSI Z77MA-G45
Intel Core i5 3570K @ 3.40GHz
8.00 GB Dual-Channel DDR3 @ 1600MHz (9-9-9-24)
Microsoft Windows 7 Professional 64-bit SP1

Test : 50 MB [E: 0.4% (0.1/14.5 GB)] (x1)
Typical IOPS Read: ~1700, Write: ~9
All results in MB/s

The bottom line:

* This is a terrible product.

* Buy a real SuperSpeed USB storage device.

* Do your research. There are plenty of manufacturers who produce them.

P.S.
If you want to stick with Kingston, get a better DataTraveller - DT111's are rock-bottom. The DataTraveller Ultimate 3.0 is a good example at R:150 W:70, and shouldn't break the bank.

Perfect. Exactly the info I was looking for. Also shame on Kingston for basically trying to pull a fast one.
