HD Tune Pro - Sequential Performance

Version and / or Patch Used: 4.55


For a 4-channel controller, the Plextor M6S performs very well. In HD Tune Pro, the 64KB sequential read averaged 450 MB/s, and the performance stays steady when reading the data.


The single pass 64KB sequential write speed averaged 354 MB/s, but this is on a fresh drive.

HD Tach - Sequential Write Performance after Random Writes

Version and / or Patch Used:


Things change a bit after a reasonable amount of random writes to the drive. HD Tach uses 128KB for the sequential read and write test. Here we see the reads holding strong near 425 MB/s, but the sequential writes drop halfway through the test. There are also two reverse spikes in the test, one getting as low as 20 MB/s. The second half of the test shows a large reduction in sequential write performance similar to what we see on Toshiba and OCZ branded SSDs.
