These drives use the industry-standard Serial ATA interface that supports FIS data transfers. It supports ATA programmed input/output
(PIO) modes 0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–6. The drive also supports the use of the IORDY signal to
provide reliable high-speed data transfers.
For detailed information about the Serial ATA interface, refer to the "Serial ATA: High Speed Serialized AT Attachment" specification.
