We are a bit disappointed with this drive, our expectations were sky high but poor Crystalmark & ATTO benchmark results have let us down. We have only managed to observe a sequential read speed of 50 MB/s which is 20 MB/s less than we were expecting, there are several similar reports from disgruntled users confirming our findings. The JetFlash 700 is priced very aggressively at £13 which is a significant discount to the original prices for this drive. We suspect that there have been several batches of these drives produced with varying performance profiles, this would explain why the drives have dropped in price so much recently. In terms of performance this drive proved to be amongst the weaker USB 3.0 flash drives. [Jun '12USBFlashPro]
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 '12USBFlashPro]
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]
