Random Read & Write
We’ll evaluate the speed of random read and write operations by measuring the time the drives take to perform them. The data block size is varied from 0.5 to 32768KB in this test.
The best drives are those whose graphs are closer to the X-axis. Thus, the A-DATA, ATP, Buffalo, Super Talent, Patriot, and both drives from Corsair are better than the others in this test. The drives from RiDATA, SanDisk and TwinMOS perform poorly here. Their access time is the highest.
The Kingston Elite looks much worse than the others in this test. It is very slow on large data blocks. The flash drives from A-DATA, ATP, Buffalo, Super Talent, Patriot and Corsair have the best results in this test.
