Average Bench: 25.4% (145th of 639)

Based on 12,289 user benchmarks.  Device: VID 0781 PID 5581 Models: SanDisk SanDisk Ultra, SanDisk Ultra

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 '14 USBFlashPro]
