SanDisk SDCZ48-032G (Flash)

Ultra USB 3.0 32GB

▲ 521,443 ▼

Release date: Q3 2013.

Average Bench: 26% (146th of 639)

Based on 33,725 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]
