Native Command Queuing:
Native Command Queuing (NCQ) is a technology designed to improve performance and reliability as the
transactional workload increases on SATA hard disk drives. When multiple read and write commands are
sent to the SATA drive, NCQ steps in to optimize the completion of these commands by grouping the
commands in order of processing efficiency, thereby reducing the mechanical workload and increase
performance from the drive. Without NCQ, the drive would process and complete each command one at a
time in the order in which it was received.
  1. NCQ Benefits:
    1. Works in all systems where host controllers support the SATA NCQ feature
    2. Provides 100% backward compatibility with non-NCQ supporting systems
    3. Allows the reordering of commands by the storage device to increase the efficiency of its data transfers
    4. Improves seek time performance from hard drives and boost performance
