A 3.5-inch Serial ATA hard disk drive A 2.5-inch Serial ATA solid-state drive. SATA was announced in 2000 [4] [5] in order to provide several advantages over the earlier PATA interface such as reduced cable size and cost (seven conductors instead of 40 or 80), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing ...
Several Parallel ATA hard disk drives. Parallel ATA, originally IDE and then standardized under the name AT Attachment (ATA), with the alias P-ATA or PATA retroactively added upon introduction of the new variant Serial ATA. The original name (circa 1986) reflected the integration of the controller with the hard drive itself.
Current hard drives connect to a computer over one of several bus types, including parallel ATA, Serial ATA, SCSI, Serial Attached SCSI (SAS), and Fibre Channel. Some drives, especially external portable drives, use IEEE 1394 , or USB .
ATA was originally designed for, and worked only with, hard disk drives and devices that could emulate them. The introduction of ATAPI (ATA Packet Interface) by a group called the Small Form Factor committee (SFF) allowed ATA to be used for a variety of other devices that require functions beyond those necessary for hard disk drives. For ...
www.intel.com /content /www /us /en /io /serial-ata /ahci.html The Advanced Host Controller Interface ( AHCI ) is a technical standard defined by Intel that specifies the register-level interface of Serial ATA (SATA) host controllers in a non-implementation-specific manner in its motherboard chipsets .
This may, as here, allow the drive to fulfill all requests in fewer rotations and thus less time. In computing, Native Command Queuing (NCQ) is an extension of the Serial ATA protocol allowing hard disk drives to internally optimize the order in which received read
