First of all, we want to see if there is any difference between the two USB 3.0 controllers we have at our disposal (ASMedia ASM1042 and EtronTech EJ168A). We connect a first-generation Kingston DataTraveler Ultimate 3.0 to them and benchmark its performance using CrystalDisk Mark.
The first screenshot shows the performance of the flash drive in our previous test session when it was connected to the EtronTech controller whereas the second screenshot is about the same drive's performance with the ASMedia controller.
There is almost no difference between the two controllers in read speed but the EtronTech is faster when writing 512KB data blocks. The ASMedia is better at processing 4KB data blocks, though.
Now we can proceed to testing the new flash drives. CrystalDisk Mark goes first.
Silicon Power Blaze B10
The speed of the Blaze B10 is far from impressive. It is roughly comparable to the speed of the lackluster Kingmax ED-01 from the previous test session.
Transcend JetFlash 700
The Transcend JetFlash 700 isn't any better. It is even closer than the Blaze B10 to the Kingmax ED-01 in performance.
Kingston DataTraveler Ultimate G2
Like in the previous test session, the Kingston drive (it's from a newer generation now) is far ahead of its opponents.
Its sequential read speed is even higher than specified: almost 130 MB/s instead of the promised 100 MB/s. It is roughly 50% faster than the first-generation DataTraveler Ultimate 3.0 in the other read tests.
Writing is not a strong point of this product, though. It is superior to its predecessor in sequential writing only but suffers a terrible performance hit in every other write test from CrystalDisk Mark. On the other hand, this doesn't prevent the DataTraveler Ultimate 3.0 G2 from being many times as fast as its opponents in terms of writing small and medium-sized files.
Seagate FreeAgent GoFlex STAA750201
The external HDD with USB 3.0 interface is overall faster than the first pair of USB flash drives we've just tested, yet the latter are better in terms of reading small and medium-sized files.
The Seagate FreeAgent GoFlex doesn't look so good when compared to the Kingston DataTraveler Ultimate 3.0 G2. Being ahead of the flash drive in sequential writing or when writing 512KB data blocks, the external HDD falls behind its opponent in the tests of reading as well as when writing small files.
