Average Access Read & Write Time

The average read/write response time is measured in a 10-minute test to read/write 512-byte data blocks with a request queue of 1.

The average read access time is less than 1 millisecond with four of the drives. These are PQI U339S, Kingston Secure, Apacer HA202 and Sony Tiny. The TwinMOS R3 doesn’t look bad, either. The other devices have a much higher read access time.

There is no such a big gap between the best and worst drives as in the previous test. The Apacer HA202, PQI U339S and Pretec ChaCha have low write access time. The Transcend V60 and PQI U190 have the highest write access time.
