The Adata Dashdrive Elite S102 Pro 64GB has proven to be a popular USB 3.0 flash drive. I did a full review of the 16GB version back in 2012 and little has changed since then. The S102 Pro still has the same robust form factor and reasonable performance profile. The 64GB S102 Pro has sequential read/write speeds of 105/50 MBps which is exactly in line with the indicated speeds on Adata's website. Peak small 4K file performance is currently measuring 7.84/1.49 MB/s which is well above average for a 64GB flash drive. At present our users have only submit four benchmark samples for this model, the peak 4K speeds are likely to drop as we accumulate more samples. The 64GB S102 Pro's performace is largely in line with its 32GB sibling and it bests its 16GB sibling by around 30%. Overall the 64GB S102 Pro Dashdrive Elite represents good value for money. [Feb '14 USBFlashPro]

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]
