Storage Technology Definitions

  • F

    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 memory

    Flash memory, also known as flash storage, is a type of nonvolatile memory that erases data in units called blocks.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.
