32GB   —

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]


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]
