2. SATA - Wikipedia

   en.wikipedia.org/wiki/SATA

   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 ...

3. SATA Express - Wikipedia

   en.wikipedia.org/wiki/SATA_Express

   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. [2]

4. Hard disk drive interface - Wikipedia

   The SAS is a new generation serial communication protocol for devices designed to allow for much higher speed data transfers and is compatible with SATA. SAS uses a mechanically identical data and power connector to standard 3.5-inch SATA1/SATA2 HDDs, and many server-oriented SAS RAID controllers are also capable of addressing SATA hard drives.

5. List of interface bit rates - Wikipedia

   en.wikipedia.org/wiki/List_of_interface_bit_rates

   Device interfaces where one bus transfers data via another will be limited to the throughput of the slowest interface, at best. For instance, SATA revision 3.0 (6 Gbit/s) controllers on one PCI Express 2.0 (5 Gbit/s) channel will be limited to the 5 Gbit/s rate and have to employ more channels to get around this problem. Early implementations ...

6. Disk array controller - Wikipedia

   Hence, its protocol is usually ATA (a.k.a. PATA), SATA, SCSI, FC or SAS. The front-end interface communicates with a computer's host adapter (HBA, Host Bus Adapter) and uses: one of ATA, SATA, SCSI, FC; these are popular protocols used by disks, so by using one of them a controller may transparently emulate a disk for a computer.

7. Advanced Host Controller Interface - Wikipedia

   The specification describes a system memory structure for computer hardware vendors to exchange data between host system memory and attached storage devices. AHCI gives software developers and hardware designers a standard method for detecting, configuring, and programming SATA/AHCI adapters.
