    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. The two vendors have described this new technology as filling a gap in the storage market between dynamic RAM (DRAM) and NAND flash.

  • A

    all-flash array (AFA)

    An all-flash array (AFA), also known as a solid-state storage disk system, is an external storage array that uses only flash media for persistent storage.

  • array-based memory

    Array-based memory is an evolving solid-state storage technology similar to flash memory but with potentially greater storage capacity. The increased capacity results from the fact that array-based memory is three-dimensional (3D) while most traditional memory and storage media are two-dimensional (2D)... (Continued)

  • array-based SSD

    An array-based SSD is a solid state drive manufactured in a form factor that can be installed in a typical storage array.

  • B

    byte

    In most computer systems, a byte is a unit of data that is eight binary digits long. Bytes are often used to represent a character such as a letter, number or typographic symbol.

  • C

    cache memory

    Cache memory, also called CPU memory, is high-speed static random access memory (SRAM) that a computer microprocessor can access more quickly than it can access regular random access memory (RAM).

  • 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.

  • column address strobe

    In computer memory technology, CAS (column address strobe) is a signal sent to a dynamic random access memory (DRAM) that tells it that an associated address is a column address. A data bit in DRAM is stored in a cell located by the intersection of a column address and a row address. A RAS (row address strobe) signal is used to validate the row address.

  • CompactFlash card (CF card)

    A CompactFlash card (CF card) is a memory card format developed by SanDisk in 1994 that uses flash memory technology to store data on a very small portable device.

  • computational storage

    Computational storage is an information technology (IT) architecture in which data is processed at the storage device level to reduce the amount of data that has to move between the storage plane and the compute plane.

  • 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.

  • D

    DAT USB drive

    A DAT USB drive is a tape drive with digital audio tape (DAT) that can be plugged into a Universal Serial Bus (USB) connection as a simple and relatively low-cost way to back up data routinely, especially on servers. DAT USB technology is expected to make it easier and more affordable for small and medium-size businesses, as well as for larger enterprise data centers, to perform backup and restore operations.

  • DIMM (dual in-line memory module)

    DIMM (dual in-line memory module) is a type of computer memory that is natively 64 bits, enabling fast data transfer.
