    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 (sometimes unofficially shortened to SATAe) is a computer bus interface that supports both Serial ATA (SATA) and PCI Express (PCIe) storage devices, initially standardized in the SATA 3.2 specification. [1]

  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. Serial Storage Architecture - Wikipedia

    en.wikipedia.org/wiki/Serial_Storage_Architecture

    Serial Storage Architecture (SSA) was a serial transport protocol used to attach disk drives to server computers.It was developed by IBM employee Ian Judd in 1990 to provide data redundancy for critical applications.

  6. Advanced Host Controller Interface - Wikipedia

    en.wikipedia.org/wiki/Advanced_Host_Controller...

    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.

    They phased out around 2015 to replace with the newer M.2 format which is faster in a traditional 2.5" SATA SSD as it uses the PCI Express standard. A solid-state drive ( SSD ) is a type of solid-state storage device that uses integrated circuits to store data persistently .

  8. Direct-attached storage - Wikipedia

    en.wikipedia.org/wiki/Direct-attached_storage

    Typical DAS featuring USB and (legacy) Firewire connectors Typical NAS using ethernet for main connectivity Direct-attached storage (DAS) is digital storage directly attached to the computer accessing it, as opposed to storage accessed over a computer network (i.e. network-attached storage).

  9. 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.
