Please note that we could not run all drives on our test notebook, a Dell Latitude D630, for the following efficiency tests.
We looked at how many workstation-type I/O operations the drives could provide. As expected from the low-level results, Hama, MemoRight, Mtron and Samsung/OCZ do best. But what’s the average power requirement to deliver this performance (80% read, 20% write and 80% random with 20% sequential access)?
As seen in our prior article, Samsung and OCZ require the least power to deliver their I/O operations per second: an average power of 1.0 W is just excellent. This would also apply to the Sandisk drive, though it doesn’t perform as well as the two others. The 1.8” Hama drive is based on an UltraATA/66 interface, which is more efficient, but doesn’t provide the bandwidth to reach a good I/O performance per watt result. Let’s see the final scores:
Once we relate I/O operations per seconds to the average power in watts, Samsung/OCZ does best.
