Serial ATA arrives
Seagate demonstrated the first Serial ATA hard drive to offer Native Command Queuing, out-of-order delivery and first-party DMA (Direct Memory Access) technologies - features that are enabled on Seagate’s newest Serial ATA hard drive, the Barracuda 7200.7. Native Command Queuing is unique to Seagate’s products because to date, only Seagate’s Native Serial ATA architecture can support this feature.
Serial ATA Native Command Queuing will significantly increase I/O performance in entry-level server systems, compared with servers using other Serial ATA or Parallel ATA solutions. It enables a Serial ATA hard drive to take a set of incoming commands and reorder them intelligently before accessing the data and submitting it back to the host for action.
Seagate’s newest Serial ATA products with Native Command Queuing will provide a new advantage for the cost-sensitive entry-level server market. Serial ATA Native Command Queuing is designed for the needs of PCs, entry-level servers and new markets such as fixed-content and near-line storage subsystems.
