Efficiency: Performance Per Watt
Although the new Samsung 256 GB SSD cannot beat the throughput we’ve seen from Intel’s X25-E drive, it requires less power to deliver almost the same transfer rates. This means that it gets very close with regards to efficiency, which we define in total read I/O operations for the benchmark run per watt. Solidata spoils its results due to the high power consumption of its X1 and X2 drives.
If we switch to workstation-type I/O activity, the efficiency measurements are different. The X25-E drive by Intel is so much superior to the other drives, as it delivers much more I/O performance at low power consumption levels.
