5 SATA interface
The drive uses the industry-standard Serial ATA interface that supports 16-bit data transfers. It
supports programmed input/output (PIO) modes 0–4; 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 draft of AT Attachment with Packet
Interface Extension (ATA/ATAPI-7), NCITS T13 1410D, subsequently referred to as the Draft ATA-7
Standard.
5.1 SATA interface signals and connector pins
The connector on MemoRight SATA NSSD is divided into a signal Segment and a power Segment.
The following tables summarizes the signals on the SATA interface connector. For a detailed
description of these signals, refer to the Draft ATA-7 Standard.
