Benchmark Results: Throughput

Analysis: Which Enterprise Capacity Point Performs Best?

You’ll receive the best throughput performance from the 300 GB drive, followed by the 600 GB model. While we don’t think peak performance numbers really make much difference, the variance in minimum throughput may become important.

The SAS 6Gb/s interface is not yet maxed out. Reading or writing from or into the drive’s buffer happens at roughly 330 MB/s. This is also the case on other enterprise drives with a SAS 6Gb/s interface. Physical performance in getting data on and off the rotating medium remains the key performance characteristic.

    It's pretty obvious that more platters/heads within the same product family does not affect performance, perhaps a little increase in access time. Overall the differences are negligible.

    But it's good to have additional solid data to backup the above statement I guess, although this test proved to be somewhat meaningless.

    Weak article. How about some real test cases?

    The differences between the drives are so negligible that you are left with price and physical data density in your data center as the only two considerations.
