Sequential Read/Write

It’s all simple here. The drive is receiving a stream of requests to read and write data blocks. The addresses of the data blocks are sequentially increasing. Once in a minute the size of the data block is changed so that we could see how the linear read/write speed depends on the data block size.

There’s only one thing to be said: the WD740GD drives are no match for the Raptor X when it comes to sequential reading/writing. Its advantage over them at writing small data blocks is most impressive (remember the Write Burst Rate graphs?)

Next goes a very interesting test that measures the drive’s performance in multi-threaded environments.
