Input/Output Interfaces
5.2 SATA Interface
These systems provide one, three, or four serial ATA (SATA) interfaces that support tranfer rates
up to 3.0 Gb/s and RAID data protection functionality. The SATA interface duplicates most of
the functionality of the EIDE interface through a register interface that is equivalent to that of the
legacy IDE host adapter.
The ICH9 DO component includes Intel RAID migration technology that simplifies the
migration from a single hard to a RAID0 or RAID1 dual hard drive array without requiring OS
reinstallation. Intel Matrix RAID provides exceptional storage performance with increased data
protection for configurations using dual drive arrays. A software solution is included that
provides full management and status reporting of the RAID array, and the BIOS ROM also
supports RAID creation, naming, and deletion of RAID arrays.
The standard 7-pin SATA connector is shown in the figure below.

The USDT system includes a notebook-type SATA connector (J102) that mates directly (i.e.,
without a cable) to a 2.5-inch mass storage device.
