Barracuda ATA V Product Manual, Rev. E 25
4.0 ATA interface
These drives use the industry-standard ATA task file interface that supports
16-bit data transfers. It supports ATA programmed input/output (PIO) modes
0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–5. The drive also
supports the use of the IORDY signal to provide reliable high-speed data
transfers.
You can use a daisy-chain cable to connect two drives to a single AT host bus.
For detailed information about the ATA interface, refer to the draft of AT
Attachment with Packet Interface Extension (ATA/ATAPI-5), NCITS T13
1153D, subsequently referred to as the Draft ATA-5 Standard.
4.1 ATA interface signals and connector pins
Figure 6 on page 26 summarizes the signals on the ATA interface connector
that the drive supports. For a detailed description of these signals, refer to
the Draft ATA-5 Standard.
