We really like this drive, it's one of our favourites. The JetFlash 780 has superb benchmark scores, at 170 MB/s this drive has the highest sequential read score we have ever seen on a consumer grade flash drive. Very interestingly the performance profile on our test unit exceeded even the manufacturers claimed speeds by over 30MB/s! The 4K write speed is less impressive, but passable at 0.3 MB/s. With reasonably solid all round performance and a reasonable price point of £23 this drive represents outstanding value for money. [Jun '12 USBFlashPro]

The 16GB DashDrive UV150 is a budget USB 3.0 drive from Adata. Unfortunately the performance profile is far more "budget" than the price. With sequential read/write speeds of 50/20 MBps the UV150 struggles to keep up with similarly priced USB 3.0 drives. Even Adata's own S102 Pro costs only slightly more but has nearly double the read speed. In terms of small file speeds the UV150 fares a little better with 4K read/write speeds of 10/0.3 MBps. Overall the DashDrive UV150 has a pretty bright red case, offers below average performance for a 16GB Flash Drive and is somewhat overpriced. There are far better alternatives available in today's market. [Feb '14 USBFlashPro]

USB Flash Drive Rankings (Price vs Performance) February 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]
