Performance in Intel IOMeter

Sequential Read & Write

As usual, we would like to start with the IOMeter sequential read and write tests. It is sending a stream of read and write requests with a request queue depth of 4. The size of the requested data block is changed each minute, so that we could see the dependence of the drive’s sequential read/write speed on the size of the data block.

Compared with the smaller solution, the read speed of Passport 250GB improved for almost all data block sizes. When reading large data chunks, the speed hit 33MB/s, which is 10% faster than what the 120GB model is capable of.

However, the linear write speed diagrams coincided everywhere except 1MB data chunks. While 120GB model performed really slowly with data blocks of this size, which could be explained by some mistake in the IDE-USB adapter, the newcomer has been cured from this issue.
