    In disaster recovery, a bare metal restore is the process of reformatting a computer from scratch after a catastrophic failure.

  • tiered storage

    Tiered storage is the assignment of different categories of data to different types of storage media in order to reduce total storage cost.

  • NAS accelerator

    A NAS accelerator (network-attached storage accelerator) is a printed circuit card that offloads TCP/IP processing from a microprocessor.

  • zoned-bit recording (ZBR)

    Zoned-bit recording (ZBR) is a method of physically optimizing the utilization of a hard drive by placing more sectors in the outer tracks than in the inner tracks.

  • memory card (flash memory card or storage card)

    A memory card (sometimes called a flash memory card or a storage card) is a small storage medium used to store data such as text, pictures, audio, and video, for use on small, portable or remote co...

  • atomic storage (atomic memory)

    Atomic storage (sometimes called atomic memory) is a nanotechnology approach to computer data storage that works with bits and atoms on the individual level.

  • petabyte

    A petabyte is a measure of memory or storage capacity and is 2 to the 50th power bytes or, in decimal, approximately a thousand terabytes.

  • AIT (advanced intelligent tape)

    Recordable DVD (sometimes called writable DVD) is a DVD technology that allows a PC user to write data one or more times to a DVD with the PC's DVD drive.

  • optical disc

    An optical disc is an electronic data storage medium that can be written to and read using a low-powered laser beam.

  • direct access

    In computer storage, direct access is the ability to obtain data from a storage device by going directly to where it is physically located on the device rather than by having to sequentially look f...

  • 8-track tape

    An 8-track tape is a hard plastic cartridge about the size of an external modem that houses a continuous loop of non-digital (analog) audio data stored on magnetic tape.

  • DLT (digital linear tape)
