Enabling or Disabling Queuing for a Unit Some drives support NCQ (Native Command Queuing), which can result in increased performance for applications that require a lot of random access of data (usually server-type applications). When enabled, NCQ can improve performance; it causes command reordering to be done on the drive, itself. www.3ware.com 141
