The Kingston DataTraveler 101 G2 (32GB) is a USB 2.0 flash drive commonly found at major electronic retailers. Moreover, it occasionally goes on sale for $9.99.

It’s main selling points are a swivel design (no cap), compact design, and multiple colors for a cheap price. The color is based on the capacity of the flash drive.

The capacity and color are as follows:

  • 8GB – Red
  • 16GB – Black
  • 32GB – Purple
  • 64GB – Green
  • 128GB – White

The swivel metal cover is solid and does not flex without excessive force. In addition, it swivels with minimal effort, but does not or slide shift on it’s own. What seemed gimmicky at first, is actually really functional and well made. With no cap to lose, this design should be employed more often.

Construction material of main body is also excellent. The drive housing is made of a strong plastic with textured stripes. There was no noticeable flex when pressed firmly.

Aesthetically, the 32GB flash drive has a translucent purple plastic body with metal chrome like swivel cover. Moreover, there are stripes to give it and round corners to give a nice dynamic look.

As for benchmarks, it preformed surprisingly well. Initial expectation were low based on the price, but it had a good read speed of 20.64 MB/s and write speed (average) of 9.24 MB/s. Nothing spectacular, but surprisingly pleasant numbers for it’s price point.

Overall the Kingston DataTraveler 101 G2 (32GB) is a great drive. Buy it for the excellent compact design and construction quality. It is a solidly built flash drive with no noticeable flex. On the other hand, read speeds and write speeds were good at best. Look elsewhere if performance matters.

Benchmarked below is the Kingston DT101 G2 (32GB) formated to have a single fat32 partition.
