Serial ATA (SATA) interface

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.

6.1

Hot-Plug compatibility

Momentus Thin drives incorporate connectors which enable you to hot plug these drives in accordance 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.
