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]
Sandisk had phenomenal success with the Sandisk Extreme which I reviewed nearly two years ago. The Extreme is still one of the best flash drives available. I had high hopes for the Ultra despite its marginally more budget orientation. Unfortunately the 16GB Ultra turned out to be a disappointment. With sequential read/write speeds of just 75/9 Mbps the Ultra lies in the bottom 25% of 16GB USB 3.0 flash drives. Small file (4K) read/write speeds clocked in at 8.35/0.08 MBps which is also in the bottom 25%. On the bright side the Ultra USB 3.0 isn't overpriced so it does represents reasonable value for money but I would happily spend a little more and get the record breaking 16GB Sandisk Extreme[Feb '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]
