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 Kingston DataTraveler Rubber G2 has a robust (water/shock resistant) form factor and an above average performance profile for a 32GB flash drive. Comparing the performance of the G2 and G1 shows that peak speeds are largely unchanged but average user speeds are significantly faster on the newer G2. We only have three samples of the 32GB G2 at present so we can't form a strong opinion yet. In terms of pricing the G2 is reasonable and is thus currently ranked 8th/27 in the 32GB group test. We will update this review when we have more performance samples.  [Jul '14 USBFlashPro]
