#9 AHCI*
AHCI gives software developers and hardware designers a standard method for detecting, configuring, and programming SATA/AHCI adapters. AHCI is separate from the SATA 3Gb/s standard, although it exposes SATA's advanced capabilities (such as hot swapping and native command queuing) such that host systems can utilize them.
"The advantage of ACHI is support for Native Command Queuing (NCQ), where the disk controller queues a bunch of I/O requests and re-orders them to optimize the way your drive retrieves that data. You'll see marginal benefits on mechanical hard disks, because the mechanical hard disks are limited by high seek times and low IOPS ratings. NCQ does not scale well on mechanical hard drives.
However, a good SSD will absolutely soar with NCQ. An SSD retrieving 16 I/O requests at once is significantly faster than if it were to retrieve those I/O requests one at a time."
