The Kingston DataTraveler Rubber G2 has a robust (water/shock resistant) form factor and an above average performance profile for a 32GB flash drive. Comparing the performance of the G2 and G1 shows that peak speeds are largely unchanged but average user speeds are significantly faster on the newer G2. We only have three samples of the 32GB G2 at present so we can't form a strong opinion yet. In terms of pricing the G2 is reasonable and is thus currently ranked 8th/27 in the 32GB group test. We will update this review when we have more performance samples.  [Jul '14 USBFlashPro]


The 32GB Jumpdrive P10 is one of the fastest flash drives I have seen in 2013. The P10 has exactly the same, superb, physical construction as its predecessor, the Jumpdrive Triton. Internally the 32 GB version of the P10 has been significantly upgraded and now yields approximately 75% better overall performance than the Triton. Lexar have managed to do this without a significant price increase which is welcome news considering the already relatively high price of the Triton. Unfortunately it's not all good news because despite its record breaking sequential speeds the P10, like the Triton, 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]


USB Flash Drive Rankings (Price vs Performance) March 2018 USB Rankings.

We highlight the best USB flash drive in terms of balanced performance and value for money using current prices, sequential read, sequential write , 4k read and 4k write speed. The speeds are combined to form a single effective speed which measures performance for tasks such as copying photos, music and videos. Effective speed is adjusted by current price and capacity to yield value for money. Finally thousands of individual user ratings are used to validate our benchmark figures. [USBFlashPro]
