The 16 GB DataTraveler Ultimate 3.0

The Kingston DataTraveler Ultimate 3.0 is a very big USB flash drive, as they go these days. In fact, at 7.4 x 2.2 cm x 1.6 cm, it is truly the biggest USB flash drive we have ever tested. All that size isn't just for show though - the drive actually packs a real heft at about 40 g.

Kingston wisely went for the simple but sturdy capped design. Any fancy mechanism would have added to the drive's considerable weight and bulk. The case is made of white plastic, with silver aluminium wrapping around the sides. The build quality is good, as you would expect from a Kingston drive.

The DataTraveler Ultimate 3.0 is backward-compatible with USB 2.0. However, some USB ports or hubs may not provide enough power. Therefore, Kingston included a Y cable which would ensure that the DataTraveler Ultimate 3.0 receives enough power while connected to USB 2.0 ports or hubs. Personally, we have had no problem running the drive directly on any USB port we tested.


Usable Capacity

Our review sample has a storage capacity of 16 GB - the smallest size available in the Kingston DataTraveler Ultimate 3.0 series. We checked that out by formatting it in NTFS using Microsoft Windows 7. The actual formatted capacity was 15,997,157,376 bytes. This is slightly (3 MB) lower than the official capacity.

By default, it's formatted using the FAT32 file system with 8 KB clusters, which works fine with all Windows operating systems. However, you should reformat it to the NTFS, or even better, the exFAT file system, if you wish to copy files that are larger than 4 GB in size (e.g. movies).

Let's take a look at its specifications.
