4.0 Serial ATA Interface These drives use the industry-standard Serial ATA (SATA) interface that supports FIS data transfers. It supports ATA programmed input/output (PIO) modes 0 to 4; multiword DMA modes 0 to 2, and Ultra DMA modes 0 to 6. For detailed information about the Serial ATA interface, refer to the "Serial ATA: High Speed Serialized AT Attachment" specification. 4.1 Hot-Plug compatibility Video 3.5 HDD drives incorporate connectors which enable you to hot plug these drives in accordance with the Serial ATA Revision 2.5 specification. This specification can be downloaded from www.serialata.org. 4.2 Serial ATA device plug connector pin definitions Table 6 summarizes the signals on the Serial ATA interface and power connectors.
