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 ...
Power cable not shown. The earliest hard disk drive (HDD) interfaces were bit serial data interfaces that connected an HDD to a controller with two cables, one for control and one for data. [a] An additional cable was used for power, initially frequently AC but later usually connected directly to a DC power supply unit. The controller provided ...
Many device interfaces or protocols (e.g., SATA, USB, SAS, PCIe) are used both inside many-device boxes, such as a PC, and one-device-boxes, such as a hard drive enclosure. Accordingly, this page lists both the internal ribbon and external communications cable standards together in one sortable table.
Parallel ATA cables transfer data 16 bits at a time. The traditional cable uses 40-pin female insulation displacement connectors (IDC) attached to a 40- or 80-conductor ribbon cable. Each cable has two or three connectors, one of which plugs into a host adapter interfacing with the rest of the computer system. The remaining connector(s) plug ...
A version of this wide connector is found inside every external SATA hard drive enclosure; when the hard drive is slid inside, it mates with a connector that supplies it with both signal and power. If the smaller side of this cable is plugged into a "powered" ESATA port, providing both 12 V and 5 V, then the wide end may be plugged into a 2.5 ...
SATA Express host-side connector, formally known as the "host plug", accepts both SATA Express and legacy standard SATA data cables. [13] [31]Connectors used for SATA Express were selected specifically to ensure backward compatibility with legacy SATA devices where possible, without the need for additional adapters or converters.
