Description: Serial Advanced Technology Attachment (SATA) is a serial link replacement of
Parallel ATA (PATA), both standards for communication with mass storage devices.
This high-speed serial link is a differential layer that utilizes Gigabit technology
and 8b/10b encoding. Some of the features of SATA compared to PATA
are increased transfer speed, hot-plug capability, and Native Command Queuing
(NCQ). The link supports full duplex but the protocol only permits frames in one
direction at a time. The other non-data direction is used for flow control of the
data stream.
Figure 2.1. The layers of the SATA protocol
SATA’s architecture consists of four layers (see Figure 2.1), Application, Transport,
Link, and Physical. The Application layer is responsible for overall ATA commands
