S - Definitions

  • S

    SerDes (serializer/deserializer)

    A SerDes or serializer/deserializer is an integrated circuit (IC or chip) transceiver that converts parallel data to serial data and vice-versa.

  • Serial ATA (Serial Advanced Technology Attachment or SATA)

    The SATA storage protocol transmits data in serial fashion between hard drives and computer systems. The nonprofit SATA-IO industry consortium authors the design specification.

  • Serial Storage Architecture (SSA)

    Serial Storage Architecture (SSA) is an open standard for high-speed access to high-capacity disk storage.

  • serial-attached SCSI (SAS)

    Serial-attached SCSI (SAS) is a point-to-point protocol used to transfer digital data between servers and SAS storage devices.

  • server-based SSD

    A server-based SSD is a solid state drive that may be manufactured in a PCI Express form factor.

  • server-based storage

    Server-based storage is a re-emerging class of data storage that removes cost and complexity by housing storage media inside servers rather than in dedicated and custom-engineered storage arrays.

  • shadow RAM

    Shadow RAM is a copy of Basic Input/Output Operating System (BIOS) routines from read-only memory (ROM) into a special area of random access memory (RAM) so that they can be accessed more quickly.

  • Shared SAS

    Shared serial-attached SCSI (SAS) is a method for attaching more than one server to a storage array via individual point-to-point or SAS switched connections.

  • shingled magnetic recording (SMR)

    Shingled magnetic recording (SMR) is a technique for writing data to disk drives in partially overlapping tracks to boost areal density and overall capacity.

  • short stroking

    Short stroking is the practice of formatting a disk drive such that data is written only to the outer sectors of the disk's platters.

  • Single namespace

    A single namespace is one presentation of file system data.

  • single-electron memory (SEM)

    Single-electron memory (SEM) refers to experimental hardware technologies in which the position or presence of a single charge carrier, usually an electron, makes the difference between the logical low (0) and high (1) states in a digital system.

  • single-level cell (SLC) flash

    Single-level cell (SLC) flash is a type of solid-state storage that stores one bit of data per cell of flash media.

  • Skyera

    Skyera was an all-flash array vendor that Western Digital's HGST subsidiary purchased in an all-cash transaction in December 2014.

  • SmartMedia card

    A SmartMedia card (originally called a solid-state floppy disk card, or SSFDC) is a memory card developed by Toshiba that uses flash memory to store data and to make it portable among devices, such as digital cameras, personal digital assistants (PDAs), and other handheld devices.
