hIOmon SSD Performance Monitor - Understanding desktop usage patterns.

Here I look at the highest IOP count xfer size that occurred for Black Ops Single and Multi Player.

The highest read IOP count xfer size for Black Ops SP was 4kB, with random reads accounting for 142.26 MiB and sequential reads accounting for 10.17MiB. – Total 4kB reads = 152.43MiB.

The total data transferred from all xfers monitored equated to 1, 690.27 MiB, so the total amount of 4kB reads xfers account for ~9% of xfers.

The largest single I/O read xfer was 28.24 MiB. The second largest single I/O read xfer was 8.99 MiB.

Approx 40% of overall xfers are random.

So...........with an avg qd of 1 and a high percentage of small xfers it seems that access time and small xfer transfer performance is key. Now I can see why I only get around ~100MB/s overall.
