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 '14 USBFlashPro]

The Flash Survivor is twice both the size and weight of most flash drives. This drive would be as well suited to smuggling diamonds as it is to carrying mp3's and word documents around. If you need a seriously robust flash drive, then this is almost certainly going to be your best choice. From a performance perspective the Flash Survivor is slightly below average but there are no glaring weaknesses, it has a well-rounded performance profile. Finally in terms of value this drive is towards the bottom of the pile unless you need super rugged features in which case it's a very good option. [Jun '12 USBFlashPro]
