Lexar Jumpdrive S57 USB 3.0 Flash Drive Review
 

As we have seen with the S75 JumpDrive model, the S57 ships with multiple color schemes, for an easier drive capacity identification. The drive does come with a slim design and incorporates a protective sliding cover that is semi-transparent, for a catchier look. Regarding the performances, we can see decent write speeds and good reads for an USB 3.0 drive; depending on the SKU we will go with, the drive performances will also be different.
