31 USB 3.0 Thumb Drives, Tested And Reviewed

Results: 512 KB Random Read And Write Performance

The TransMemory-EX posts the fastest 512 KB random reads in the round-up, hitting 256 MB/s. Five other USB 3.0 thumb drives break the 200 MB/s barrier, including the drive that wins our round-up overall, SanDisk's Extreme. The Kingston DataTraveler R3.0, with its not-so-inspiring 67.5 MB/s, reminds us that not all USB 3.0-connected thumb drives are fast.

The Extreme repeats its stellar 4 KB random read performance in our 512 KB random write metric. Calling the other drives "competition" gives them far too much credit, as SanDisk posts a 45.2 MB/s result, which is three times faster than the runner-up (Adata's S102 Pro 64 GB) and more than five times faster than Adata's third-place N0005.

    It would have been nice to see price performance index as well but good article.

    It's not a surprise the Sandisk wins because this USB drive is actually a small SSD.. It uses the same controller used in Sandisk's ReadyCache SSD drives... the great thing about it is it is priced reasonably considering.. :)

    Been using this usb3.0 *SSD from Sandisk for half a year and I haven't got disappointed.Great device for the price. The only drawback I found is that its enclosure gets quite hot after 15mins of heavy use ( benchmarking ) because heat might reduce a SSD' durability.

    The sandisk extreme works well.

    I currently have the 16GB version (was $20 when I got it)

    not as good as the the 64GB version but it is still really good

    I have the 32 GB version of the SanDisk Extreme and it is a great thumb drive. The 16 GB version is a bit slow and the 64 GB is a bit expensive for some, the 32 GB is a good middle ground. Here are the benchmarks I used when trying to decide which USB3.0 drive to get:

    There is a toggle on that site that allows you to view the benchmark results for all three sizes.

    Here is the full whoratesit.com article as a complement to the Toms article: http://www.whoratesit.com/Best-Flash-Drive/Comparison/1#rank1

    In my case the limiting factor is the controller / port. I've got three USB 3.0 controllers: On my notebook at work, built into the motherboard at home, and a PCI-E one. The PCI-E one is twice the speed of the lowest one in 4k random writes.

    If I were home I'd post the controller and the thumb drive model, but I'm not there so don't ask.

    Very interesting read I assumed most 3.0 usb drives were similar in speed.

    Why no Corsair Flash Survivor? :( I love mine, albeit the write times aren't the speediest.

    Too true, don't forget the controller speed. The Etron controller in my old-ish Z68 board ensures my USB 3.0 devices rarely go above 25 MBps even though I can get double that performance on my newer work computer.
