The 64GB Jumpdrive P10 is Lexar's 2013 upgrade to their flagship Triton range of flash drives. The P10 shares the same excellent body as the Triton and delivers actual speed increases in the region of 30% over its predecessor. In terms of price there is not a huge increase so I do prefer the 64GB P10 to the 64GB Triton but the upgrade is less pronounced than when going from the 32GB Triton to the 32GB P10 where performance increased by nearly 75%. Despite its record breaking sequential speeds the 64GB P10, like the Triton and the other P10 drives, struggles in the area of small 4K random writes. If you are planning to use this drive to copy small files or to host applications you will likely be disappointed otherwise for tasks such as copying video and audio files this is one of the fastest flash drives you can currently buy. [Aug '13 USBFlashPro]

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]
