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 first diagram shows the time it takes to perform random reading. The smallest, i.e. the best, results are provided by the Apacer HA202 and Kingston Secure. The A-DATA PD3 and Pretec ChaCha spend somewhat more time to do random reading. The A-DATA PD0 and TwinMOS R3 are the slowest drives – and they have performed poorly in the previous test, too.

It’s quite predictable with random writing: the Apacer HA202 has the best result. Next goes the Kingston Secure. The A-DATA PD3 occupies third place. The A-DATA PD0 and TwinMOS R3 are again the slowest of all.
