Conclusion 
Average Bench 23.6%

This could have been a serious contender in the high speed USB 3.0 arena. On paper at least, with 260/220 MB/s read/write speeds, this drive would have had the highest sequential speeds we have seen to date on a 64GB drive. The GT Turbo was delayed by several months by Corsair, and when finally released it proved to fall far short of the advertised headline speeds. In reality it can only write at around 80 MBps and has an extremely weak 4K Random write speed. Corsair have offered refunds to the multitude of unhappy customers that bought this drive in anticipation of it setting new speed records. There are far faster drives available. [Aug '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.
