Storage Technology Definitions

  • F

    flash memory card

    Flash storage memory cards use nonvolatile semiconductor memory to store pictures, audio and video data on portable and remote devices.

  • flash storage

    Flash-based storage, based on flash memory, is used for data repositories, storage systems and consumer devices, such as USB drives, smartphones and solid-state drives.

  • FPM DRAM (Fast Page Mode DRAM)

    Prior to newer forms of dynamic random access memory (DRAM), FPM DRAM (Fast Page Mode DRAM) was the most common kind of DRAM in personal computers.

  • FRAM (ferroelectric RAM)

    FRAM (ferroelectric RAM) is random access memory that combines the fast read and write access of dynamic RAM (DRAM) - the most common kind of personal computer memory - with the ability to retain data when power is turned off (as do other non-volatile memory devices such as ROM and flash memory).

  • FreeNAS Project

    The FreeNAS storage operating system is compatible with most major protocols and storage hardware and provides file sharing in a NAS environment.

  • G

    garbage collection

    Garbage collection is the systematic recovery of pooled computer storage that is being used by a program when that program no longer needs the storage. (Continued...)

  • geek speak

    Geek speak is how the uninitiated refer to the jargon and special vocabulary used by those immersed in computers and other fields of information technology.

  • Ghost

    Ghost is a software product from Symantec that can clone (copy) the entire contents of a hard disk to another computer's hard disk or to storage media.

  • giant magnetoresistive effect

    GMR is the newest generation of hard disk drive storage.

  • gigabyte (GB)

    As of this writing, 1 gigabyte of storage translates to approximately 200 songs or 250 10-megapixel photos.

  • global namespace

    Global namespace is a feature that provides a consolidated view into multiple Network File Systems (NFS), Common Internet File Systems (CIFS), network-attached storage (NAS) systems or file servers that are in different physical locations.

  • GlusterFS (Gluster File System)

    GlusterFS (Gluster File System) is an open source distributed file system that can scale out in building-block fashion to store multiple petabytes of data.

  • green storage

    Green storage is the practice of using a variety of "clean energy" storage methods and products to cut down on a data center's carbon footprint, as well as cost.

  • grid storage

    Grid storage is a general term for any approach to storing data that employs multiple self-contained storage nodes interconnected so that any node can communicate with any other node without the data having to pass through a centralized switch. (Continued...)

  • H

    HA storage (high-availability storage)

    High-availability storage (HA storage) is a storage system that is continuously operational or provides at least 99% uptime.
