Average Bench: 65.9% (10th of 639)

Based on 3,391 user benchmarks.  Device: VID 0781 PID 5580 Model: SanDisk Extreme

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.  [Mar '13 USBFlashPro]


Above average average bench

The SanDisk Extreme USB 3.0 32GB averaged 34.0% lower than the peak scores attained by the group leaders. This isn't a great result which indicates that there are much faster alternatives on the comparison list.


Avg. 4K-64Thread Write Speed 9.93MB/s
Avg. 4K Random Write Speed 8.61MB/s

Poor consistency

The range of scores (95th - 5th percentile) for the SanDisk Extreme USB 3.0 32GB is 68%. This is a particularly wide range which indicates that the SanDisk Extreme USB 3.0 32GB performs inconsistently under varying real world conditions.

The best USB 3.0 / 2.0 stick, very fast and good price ! Intr-adevar, acesta-i cel mai bun stick de 32 Gb. pe USB 3.0 / 2.0, precum si cea mai buna alternativa la un HDD extern (de min. 500 Gb., tot pe USB 3.0), dar daca vrem mult mai spatiu de stocare peste cei 32 de Gb. ai acestui SanDisk, atunci e mult mai rentabil un HDD extern pe USB 3.0 de min. 500 Gb. !!!
