The 16GB Sandisk Extreme has led my USB 3.0 Flash drive group test since it was released back in Jun '12. Often with flash based devices, write speed scales linearly with capacity and the Extreme is no exception. The sequential write speeds for the different capacities are: 16GB = 62 MB/s, 32GB = 117 MB/s and 64GB = 188 MB/s. In the 64GB category there are several alternatives to the Extreme including the new Corsair Flash Voyager GT Turbo, Kingston HyperX and Patriot Supersonic Magnum. In the 16 GB category there are also a few viable alternatives but in the 32GB category I have yet to come across a drive that even comes close to the Sandisk Extreme from either a value for money OR performance perspective.  [Mar '13 USBFlashPro]

The new Adata Dashdrive UV128 has a performance profile that closely matches its older, and recently rebranded, Dashdrive Elite S102 Pro sibling. Comparing the two shows that the drives are nearly identical except for form factor. Personally I prefer a retractable form factor as USB caps are easily lost. Overall in terms of performance the Dashdrive UV128 is slightly above average and in terms of value for money it is also reasonable. [Jul '13 USBFlashPro]
