Performance in Intel IOMeter
Sequential Read & Write
We’ll start out with the synthetic IOMeter benchmark. This pattern measures the drive’s sequential read and write speeds on data blocks of different size (from 0.5 to 1024KB).
The first diagram shows the sequential read speed of the drives and there are two clear leaders here, the drives from Apacer and Kingston. The former looks better with large data blocks, but the latter is superior on small data blocks. The A-DATA PD3 and the Pretec ChaCha should also be distinguished. They are slower at reading than the two leaders, yet are much faster than the other models. The A-DATA PD0 and the TwinMOS R3 are the slowest flash drives in this test.
Note also that the read speed of each drive stops to grow up further after 64KB data blocks.
The sequential write diagram shows three leaders. The Apacer HA202 is the first of them, followed by the Kingston Secure. The A-DATA PD3 is third on the podium. The A-DATA PD0 and TwinMOS R3 are the slowest in this test. They produce stable, but poor results.
And here again we can see that each drive reaches its highest speed on 64KB and larger data blocks.
