Some drives support command queuing, a feature that can result in increased
performance for applications that require a lot of random access of data
(usually server-type applications). This is accomplished by causing command
reordering to be done on the drive.
In order to make use of command queuing, the feature must be enabled at both
the drive and the controller. You can enable support for command queuing on
a per-unit basis, as described below.
You can see whether command queuing is supported and enabled for a
particular drive in the Drive Details window. For details, see "Drive Details
window" on page 221.
