The Kingston DataTraveler SE9 (DTSE9) is commonly found for a cheap price. Benchmarked is the 16GB model formated to have a single fat32 partition.

As usual for these cheap flash drives, performance is slow though better than average for it’s price class. However, the construction and size of this device is outstanding. The outer casing is made of aluminum, and it’s very robust. There are no moving parts or caps to remove. In addition, it’s tiny compared to other flash drives. According to Kingston’s marketing literature this flash drive is designed to be portable and to complement Ultrabooks and tablets. That is a claim I fully agree with as the device easily fits in a pocket without being damaged. Moreover, it cleanly fits into the USB port without a large bulge. It’s not a micro flash drive, but I happily leave one connected to the USB port on my Blu-ray player.

The Kingston DTSE9 is definitely a worth while purchase for the robust construction of the flash drive. On the other hand, if fast read/write speeds are required then this drive may disappoint. Data integrity and performance, though, should be reliable as the device comes with a five-year warranty.
