The alphabetically last, but not least in importance, Western Digital comes.

All drives from WD show nearly the same performance under this workload, only the WD1200JD breaks away from the others, showing the same dislike for writes as the Hitachi HDS722512VLAT20. However, like the Hitachi drive, the WD1200JD catches up with the group at high percentages of writes. Note the low efficiency of lazy write algorithms of the WD1200BB/60 – it seriously lags behind the others when there are many writes in the queue.

Now, the workload becomes higher.

The graphs have the same shapes as under the smaller workload.
