    3.5" SSD (3.5 solid-state drive)

    A 3.5 solid-state drive (SSD) is a data storage device designed for the 3.5-inch hard disk drive (HDD) form factor. It fits into the drive slot as a same-sized HDD in a portable computer, enterprise server, or storage system.

  • 3D NAND flash

    3D NAND is a type of flash memory in which memory cells are stacked vertically in layers, in comparison to planar NAND, which uses a single layer of memory cells.

  • 3D XPoint

    3D XPoint is memory storage technology jointly developed by Intel and Micron Technology Inc.

  • A

    all-flash array

    An all-flash array is a solid state storage disk system that contains multiple flash memory drives instead of spinning hard disk drives. A flash array can transfer data to and from solid state drives (SSDs) much faster than hard disk drives.

  • C

    client solid state drive (SSD)

    Client solid state drive (SSD) is a marketing term used by original equipment manufacturers (OEMs) and value-added resellers (VARs) to differentiate between solid state drives built for consumers and solid state drives built for the enterprise.

  • conductive metal-oxide (CMOx) technology

    Conductive metal-oxide (CMOx) technology is a nonvolatile storage technology that works by moving oxygen ions between conductive and insulating metal-oxide layers within a single chip.

  • E

    eMMC (embedded MultiMediaCard)

    An embedded MultiMediaCard (eMMC) is a small storage device made up of NAND flash memory and a simple storage controller.

  • enterprise MLC (eMLC)

    Enterprise MLC (eMLC) is a type of MLC flash that has been enhanced to accommodate more write cycles than consumer-grade MLC flash offers.

  • enterprise SSD (enterprise solid-state drive)

    An enterprise SSD (also known as an enterprise solid-state drive or enterprise solid-state disk) stores data persistently or caches data temporarily in nonvolatile memory and generally provides higher performance and greater endurance than consumer or client SSDs.

  • F

    flash cache appliance

    A NAND flash cache appliance is a dedicated network appliance that resides between the hosts and underlying storage arrays.

  • flash controller

    A flash controller is the part of flash memory that communicates with the host device and manages the flash file directory.

  • flash file system

    Flash file systems are designed specifically for memory devices. A well-designed flash device and flash file system ensure flash-based capabilities are used efficiently.

  • flash-based solid state drive (SSD)

    A flash solid state drive (SSD)  is a non-volatile storage device that stores persistent data in flash memory. 

  • floating gate

    In flash memory, a floating gate is a CMOS-based transistor that is capable of holding an electrical charge.

  • fresh out of the box (FOB)

    Fresh out of the box (FOB) is a term used in solid state storage (SSS) to describe a flash memory device that has experienced few or no program/erase (P/E) cycles since the device was manufactured.
