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]
The 32GB Datatraveler G4 has a below average performance profile for a 32GB USB 3.0 flash drive but it's priced aggressively so it still represents reasonable value for money. With sequential read/write speeds of 77/32 MB/s the G4 sits near the bottom of the pack for sequential performance. Small file 4K performance is relatively better with read/write speeds of 7.5/0.32 MB/s but again far from class leading. Overall the Datatraveler G4 scored an effective speed of 47.5 MB/s which ranks it 19th out of 25 32GB USB 3.0 Flash drives. The highlight of the G4 is its superbly low price point, a lot of 16 and 8GB drives cost more. If you plan to use the drive regularly it's certainly worth spending a little more but otherwise the G4 is a reasonable option. [Mar '14USBFlashPro]
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]
