Performance per Watt: Streaming Reads

Intel's X25-M Solid State Drive Reviewed

The streaming read throughput benchmark reflects what we found in the low-level throughput tests: Intel’s X25-M is extremely quick, while the Samsung SSD takes second place. It is obvious that the Intel 10-channel design has its impact in this test, as the performance results show a larger advantage for the Intel solution than in the throughput tests. Clearly, the controller is doing its job well.

Again, the power consumption of both SSDs is attractively low, especially looking at the level of performance. Let’s see what the performance per watt ratio looks like:

Intel’s drive is much faster, while being more efficient No further questions.

The I/O streaming read efficiency tests were performed on our storage reference test system. Please refer to the test setup page for details.

    Here it is, the new X25-M; the name sounds very much like an experimental hypersonic plane. And the analogy isn’t far off, since the new flash SSD provides excellent performance.

    What the other companies are doing? They should have had a better performance as they demand to be expertise in this peripheral device. X-25 is going to head ..that's for sure. Waiting to see what the other vendor's do to boost up their performance.

    On page 13 the final graph looks wrong, given the stream read performace and the average power of the previous graphs the performance per watt for the intel should be closer to 810 not the 5000+ given
