When multiple drives are connected to the SiI 3132 via a port multiplier
such as Silicon Image's SiI 3726, RAID 0, 1, 10 and 5 are supported.
In addition to these advanced features, the introduction of SATA II products brings a number of key performance improvements, including 3Gb/second interface speed, Native Command Queuing (NCQ), and Port Multiplier
Multiple drives connect to a 1.5 or 3Gb/s Serial ATA Port Multiplier
. The collective drive data rate with the 3GB/s Serial ATA Port Multiplier
equals 240MB/s into the host controller.
Some of the other key enhanced SATA features were published by the SATA II working group in several specifications and included Native Command Queuing (NCQ), Port Multiplier
, Staggered Spin Up, Port Selector, External SATA, and Hot Plug.
