Having just done a review of the 16GB Sandisk Ultra which wasn't a great performer but still managed to represent reasonable value for money, I was expecting much the same from the 32GB Ultra. Generally speaking moving from the 16 to 32 GB capacity results in a doubling of the write speed. This was not the case for 32GB Ultra which had a performance profile that was almost identical to its 16GB sibling. As a consequence the 32GB Ultra is amongst the bottom 5% of 32GB Flash Drives in terms of performance and only slightly better in terms of value for money. There is no doubt that it's worth spending a little more on the superb 32GB Sandisk Extreme[Feb '14 USBFlashPro]

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 '14 USBFlashPro]
