    SAS SSD (Serial-Attached SCSI solid-state drive)

    A SAS solid-state drive (SSD) is a NAND flash-based storage or caching device that uses the serial-attached SCSI (SAS) interface to connect to the host computer and fits into the same slot as a hard disk drive (HDD).

  • semiconductor fab

    A semiconductor fab is a manufacturing plant in which raw silicon wafers are turned into integrated circuits. 

  • server-based SSD

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

  • 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 level cell (SLC) flash

    Single level cell (SLC) flash is a type of solid-state storage (SSS) that stores 1 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.

  • SNIA Solid-State Storage Initiative (SSSI)

    The Solid State Storage Initiative (SSSI) is an initiative formed by the Storage Network Industry Association (SNIA) to help foster and grow the adoption of solid-state storage in enterprise and client environments.

  • solid state drive (SSD) capacity

    solid state drive (SSD) capacity

  • solid state module (SSM)

    A solid state module is solid state storage that resides in a Dual In-line Memory Module (DIMM) or similar form factor. 

  • solid state storage (SSS) garbage collection

    Garbage collection, like TRIM, pro-actively eliminates the need for whole block erasures prior to every write operation.

  • solid state storage auto-tiering

    Solid state storage auto tiering is automatically moving data that needs to accessed frequently to more expensive single-level cell (SLC) solid state storage and moving data that does not require frequent access to less expensive multi-level cell (MLC) solid state media or other lower cost, higher capacity drives.

  • Solid State Storage Performance Test Specification (SSS PTS)

    Solid State Storage Performance Test Specification (SSS PTS) is a set of procedures for evaluating the performance of NAND-based solid state storage (SSS). 

  • solid-state storage UBER

    Solid-state storage UBER (unrecoverable bit error rate) is the percentage of bits that have errors relative to the total number of bits that have been read.

  • SolidFire

    SolidFire is a Boulder, Colorado-based vendor of all-flash storage arrays that was acquired by NetApp on Dec. 21, 2015.

  • SSD (solid-state drive)

    Learn what a solid-state drive (SSD) is, why SSDs are replacing electromechanical hard drives and which form factors are approved by the Solid State Storage Initiative (SSSI).
