| # Sequential read and write speeds are tested, these are expected to be |
| # high. Random reads should also be fast, random writes are where crap |
| # drives are usually separated from the good drives. |

| # This uses a queue depth of 4. New SATA SSD's will support up to 32 |
| # in flight commands, so it may also be interesting to increase the queue |
| # depth and compare. Note that most real-life usage will not see that |
| # large of a queue depth, so 4 is more representative of normal use. |
