    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).

  • SSD caching

    SSD caching, also known as flash caching, is the temporary storage of data on NAND flash memory chips in a solid-state drive so data requests can be met with improved speed.

  • SSD form factor

    An SSD form factor is the size, configuration or physical arrangement of solid state storage (SSS) media.

  • SSD purge (solid state drive purge)

    SSD purge is the process of returning a flash memory device to its original state at the time of manufacturing and effectively erasing any data that has been written to the device. A purge is sometimes called a hard reset or digital sanitization. 

  • SSD RAID (solid-state drive RAID)

    SSD RAID (solid-state drive RAID) is a methodology commonly used to protect data by distributing redundant data blocks across multiple SSDs.

  • stand-alone solid state storage (SSS)

    Stand-alone SSS is solid state storage that is not integrated with spinning hard drive disks as in a hybrid flash array.

  • steady state

    Steady state is a condition in which a solid state flash drive has experienced enough program/erase (P/E) cycles that performance times for write operations becomes stable and can be evaluated in a consistent manner.
