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]

ALL FAQs »

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
