...model, this section. 5 SATA devices SATA devices include initiators (SATA controllers), port multipliers, and targets (SATA drives) as shown in a SATA domain. Port multipliers connect initiators to targets in Figure 5. These devices, and the cabling that connect them, are described in this feature ...access (DMA) engine in desktop PCs (non-hot plug). Native command queuing enables a hard drive to take multiple requests for server and networked storage applications. SATA 3.0-Gb/s hard drives will be able to queue and execute requests without any assistance from the processor and ...
