IO Performance:
--------------

NCQ - Native Cmd Queueing - SATA II - 32 cmds

TCQ - Tagged Cmd Queuing - SCSI 2 - 216 cmds possible (64 cmds supported by most disk queues)

- Reordering of cmds when requests for sectors spaced far from one another.

- attempts to reduce disk seek time and rotation latency by optimising order in which sectors are found.
