  • multi-level cell (MLC) flash

    Multi-level cell (MLC) flash writes two data segments to the same cell, effectively doubling the capacity of flash storage media.  Definition

  • terabyte (TB)

    A terabyte (TB) is a measure of computer storage capacity that is 2 to the 40th power or approximately a trillion bytes (that is, a thousand gigabytes).  Definition

  • 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 traditio...  Definition

  • Kilo, mega, giga, tera, peta, and all that

    Prefix multipliers are used in data storage, data communications, electronics, and physics to denote extremely small and large quantities. Read definitions for terms including kilo, mega, giga, tera and peta here.  Definition

  • array

    In general, an array is a number of items arranged in some specified way - for example, in a list or in a three-dimensional table.  Definition

  • gigabyte (GB)

    A gigabyte (GB) is a measure of computer data storage capacity and is "roughly" a billion bytes.  Definition

  • storage medium

    In computers, a storage medium is any technology (including devices and materials) used to place, keep, and retrieve data.  Definition

  • byte

    In most computer systems, a byte is a unit of data that is eight binary digits long... (Continued)  Definition

  • 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...  Definition

  • hard disk

    A hard disk is part of a unit, often called a "disk drive," "hard drive," or "hard disk drive," that stores and provides relatively quick access to large amounts of data on an electromagnetically charged surface or set of surfaces.  Definition

  • Gartner analyst on data deduplication for primary storage

    Primary storage data deduplication will take hold first with network-attached storage (NAS) and then block-based options over the next 18 months, says Gartner analyst, who advises users to architect with new products in mind.  Podcast

  • Podcast: Solid-state drives entering enterprise storage environments

    What should a storage administrator be doing today in terms of planning for solid-state drives entering the storage environment? Jeff Janukowicz, research manager at IDC for solid-state drives and hard drive components, discusses the impact SSDs are ...  Podcast

  • Boost Array Performance Podcasts

    As data wends it way from hosts, through the fabric and to the array, it encounters many potential bottlenecks. But that also means there are a number of ways to improve storage subsystem performance. The key to the tuning process is a thorough under...  Podcasts
