The 64 GB Flash Voyager GT has an impressive performance profile. You wouldn't know it without checking the serial numbers but Corsair have released several variants of the USB 3.0 Voyager GT. With each successive version slightly besting its predecessor, this is the best flash drive I have seen from Corsair to date, it even beats the GT Turbo which is more recent. The strongest area of relative performance for the GT is 4K read speed where it achieves 20 MB/s, unfortunately its 4K write speed is almost equally poor clocking in at just 0.15 MB/s. I don't generally like that sort of imbalance in a flash drives performance because it means that from time to time I will get stuck waiting an inordinate amount of time for a data transfer to complete. Taken as a whole the 64 GB GT is a competent performer that's let down by its relatively weak 4k write speed. [Sep '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.
