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.

Having just done a review of the 16GB Sandisk Ultra which wasn't a great performer but still managed to represent reasonable value for money, I was expecting much the same from the 32GB Ultra. Generally speaking moving from the 16 to 32 GB capacity results in a doubling of the write speed. This was not the case for 32GB Ultra which had a performance profile that was almost identical to its 16GB sibling. As a consequence the 32GB Ultra is amongst the bottom 5% of 32GB Flash Drives in terms of performance and only slightly better in terms of value for money. There is no doubt that it's worth spending a little more on the superb 32GB Sandisk Extreme. [Feb '14USBFlashPro]
We highlight the best USB flash drive in terms of balanced performance and value for money using current prices, sequential read, sequential write , 4k read and 4k write speed. The speeds are combined to form a single effective speed which measures performance for tasks such as copying photos, music and videos. Effective speed is adjusted by current price and capacity to yield value for money. Finally thousands of individual user ratings are used to validate our benchmark figures. [USBFlashPro]
