Sandisk had phenomenal success with the Sandisk Extreme which I reviewed nearly two years ago. The Extreme is still one of the best flash drives available. I had high hopes for the Ultra despite its marginally more budget orientation. Unfortunately the 16GB Ultra turned out to be a disappointment. With sequential read/write speeds of just 75/9 Mbps the Ultra lies in the bottom 25% of 16GB USB 3.0 flash drives. Small file (4K) read/write speeds clocked in at 8.35/0.08 MBps which is also in the bottom 25%. On the bright side the Ultra USB 3.0 isn't overpriced so it does represents reasonable value for money but I would happily spend a little more and get the record breaking 16GB Sandisk Extreme [Feb '14 USBFlashPro]

The 16GB version of this drive currently ranks 4/27 in my USB 3.0 flash drive group test. The 32GB version has the same great aesthetics as its 16GB sibling but due to controller parallelization, write speed performance expectations double in this larger capacity category. Consequently the 32GB Triton no longer stands heads and shoulders above its competition in the sequential write speed tests. The Jumpdrive Triton 32GB still offers both reasonable performance and an extremely stylish metal chassis however in terms of value for money and outright performance it is difficult to justify. The new range of Lexar P10 drives should come to market later this year, they promise to have far stronger performance figures. [Mar '13 USBFlashPro]
