For real world usability this is currently the best 64GB flash drive (superseded by the Ventura Ultra - 2014). It has a very balanced performance profile with an exceptional 4K random write speed. The 16GB version of the Extreme is currently the value leader in the USB 3.0 flash drive shootout. At present there are no viable alternatives to the 64GB Extreme in fact the Corsair voyager GT turbo is the only drive on the horizon that may challenge the Sandisk any time soon. There are however several reports (Newegg, Amazon) of compatibility issues with this, the 64GB version (other versions are fine), so if you do go for the 64GB version, don't throw the receipt away in a hurry. [Feb '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.
