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 '14USBFlashPro]
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]
