This is one of the Kingston's newest flash drives and yet another drive from Kingston with no claimed read or write speeds on the official documentation, not an encouraging sign (Kingston have since quoted Read/Write speeds of 40/10 MB/s). With a sequential write speed of 9.9 MB/s and a random write of 0.046 MB/s This drive is actually slower at writing than a lot of USB 2.0 drives, it's seriously dog slow. I really don't understand why Kingston have released a flash drive with specs like this but then I guess they didn't write the speed in the specs for a reason! There is no reason to buy this drive, as there are far better USB 3.0 flash drives out there for approximately the same money. Kingston's own DTR30 is a far better drive for an extra five pounds. If you really don't want to spend more than £10 then the Verbatim Store n Go V3 is better for the money. [Jun '13 USBFlashPro]

The benchmark scores for the SanDisk Extreme were stunning. Until now every flash drive we have tested has shown a serious weakness in the area of 4K random writes. The SanDisk Extreme achieved a 4K random write speed of 2.1 MB/s which was over three times faster than the best of the rest, unfortunately we were unable to get consistent measurements but 2.1 MB/s was towards at the lower end of the range (10.8 MB/s - 1.71 MB/s) we observed. We suspect the inconsistency relates to the way the controller batches page cleanup. The other benchmark observations were all consistent and to date this drive has the highest sequential read we have seen on a 16GB flash drive. The SanDisk Extreme has not been released in the UK. Our test unit had to be shipped from Hong Kong where we were able to purchase it at at an extremely reasonable price. We will update the price if/when the drive becomes officially available in the UK ... [Jul '12 USBFlashPro]
