4.0Serial ATA (SATA) interface

These drives use the industry-standard Serial ATA interface that supports FIS data transfers. It supports ATA pro- grammed 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 Attach- ment” specification.

4.1Hot-Plug compatibility

Pipeline HD Mini Series SATA drives incorporate connectors which enable you to hot plug these drives in accor- dance with the Serial ATA: High Speed Serialized AT Attachment specification revision 2.0. This specification can be downloaded from http://www.serialata.org. This device requires a COMRESET from the host after a hotplug event.
