For testing, we went with a couple runs of Crystal Disk Mark, which gives us a good idea of what kind of performance can be expected in both sequential transfers as well as 4k (small file) transfers. All testing is done using the native Intel USB 3.0 controller included with the Ivy Bridge processor and the (Z77) Panther Point chipset.
Here we’ve compiled a chart of each drive’s performance in terms of sequential reads and writes. For reference, we’ve also included an old SanDisk Cruzer 4GB USB 2.0 flash drive. Of all the drives, the only drive that didn’t make its advertised transfer speeds was the Corsair Voyager GT, which scored only a couple of MB/s short (<2MB/s) of its advertised 220MB/s sequential read and 110MB/s sequential write.
In terms of sequential read performance, the Kingston HyperX dominated the charts putting up a solid 252.7 MB/s, 27.7MB/s faster than its advertised sequential read speed and 4.2MB/s faster than the second fastest drive in terms of sequential read performance, the Patriot Supersonic Magnum. All drives reviewed today were capable of achieving greater than 100 MB/s sequential reads.
In terms of sequential write performance, the SanDisk Extreme and the Lexar JumpDrive Triton led the pack coming in at 181.6 MB/s and 181.3 MB/s respectively with the Patriot Supersonic Magnum trailing in at third place with a sequential write performance of 154.1MB/s. All drives reviewed today with the exception of the ADATA N005 Pro was capable of achieving greater than 100 MB/s sequential writes.
Switching over to the 4K numbers, we can see that for the most part, every drive struggled with 4K writes with the exception of the SanDisk Extreme, which scored a whopping 10.18 MB/s, which just so happens to be ~10MB/s faster than every other drive reviewed today.
In terms of 4K reads, the top drive here is the Corsair Voyager GT which scored a whopping 21.66MB/s. This means that those looking for a flash drive for a USB bootable Linux distro or something will find the Voyager GT or the SanDisk Extreme an excellent choice.
