A "phantom" drive created by setting aside a section of RAM as if it were a group of regular sectors. Access to a RAM disk is very fast but data is lost when the system is reset or turned off.

An area of memory managed by a special device driver and used as a simulated disk. Because the RAM disk operates in memory, it works very quickly, much faster than a regular hard disk. Remember that anything you store on your RAM disk will be erased when you turn off your computer, so you must save its contents onto a real disk first. RAM disks may also be called virtual drives.

(computer science) a virtual drive that is created by setting aside part of the random-access memory to use as if it were a group of sectors; "access to a RAM disk is very fast but the data it contains is lost when the system is turned off"

a block of memory which your computer uses like a disk

a block of system memory which is made to appear like an extra disk drive

a device made from system RAM that looks like a small, simple, disk device

a device that looks like a hard disk drive to the host computer but it is made from solid-state memory chips and not rotating platters and mechanical read/write heads

a drive created in memory

a part of main memory pretending to be a normal hard disk which doesn't retain its data beyond a reboot

a part of memory which is set aside to act as a disk drive

a portion of electronic memory that has been configured to behave exactly like a physical ProDOS disk drive

a portion of memory that is allocated as a partition

a portion of RAM which is being used as if it were a disk drive

a simulated hard drive that exists entirely within your system's memory chips

a term used to represent a logical structure of allocated RAM (chips or SIMMs) capacity which simulates a data-stroage drive, albeit one that is performing at much higher speeds than a data-stroage drive is capable of acheiving

a way of using physical memory to simulate a very fast hard drive

See Memory disk.

A RAM disk emulates a hard disk using the computer's memory. Whereas a hard disk stores data permanently until it is rewritten, a RAM disk only exists as a running program, and goes away when the program stops or the computer is powered down.

Macintosh ability to temporarily designate part of RAM space for use as an incredibly fast "hard drive." Useful for Powerbook owners who want to prolong battery life by turning off their hard drive while working.

a portion of RAM (random access memory) used to simulate a disk drive. Utilizing RAM in this way allows for quicker access to information than calling it from the hard disk, but has some limitations. First, files must be copied from the hard disk to the RAM disk for each session and the new material must be copied back to the hard disk before ending the session. This is necessary because, like normal RAM, a RAM disk clears all data when the computer is shut down. Additionally, a power failure will cause the loss of data on a RAM disk.

A virtual drive which uses part of a computer's RAM to store data. A RAM disk provides quick access to information, but unlike written data, that data in a RAM disk is lost when the computer is turned off.

A technique for temporary data storage in memory using a portion of memory allocated as a virtual disk.

RAM set aside for use as a disk drive. All data is lost when computer is power-cycled, reset or warm-booted.

Part of main storage used as a disk unit. Reading and writing being much faster in storage than on disk, RAM disk files speed up the program execution.

A memory-resident program which emulates a hard drive. The DRAC 4 maintains a RAM disk in its memory.

or RAM cache - is the opposite of virtual memory. RAM is used to buffer information off the disk, just in case it is needed repeatedly or quickly. This can consumes 1-2 MB of RAM on an 8 MB system, hampering performance. The user can disable the RAMdisk by commenting out the appropriate line in the CONFIG.SYS file under Windows, or via the Memory Control Panel on the Macintosh. There may be multiple applications trying to manage disk and RAM caching. Your CD-ROM driver, Windows and Director all may attempt to cache data from the CD or RAM to the hard drive at various times.

a partition of the RAM memory that is treated as a separate disk

A portion of the available RAM reserved for use as a temporary storage device. A user can configure a RAM disk or disable it altogether using controls in the Memory control panel.

That area of RAM that facilitates disk caching. (See also disk caching.)

A cross between a disk and random-access memory. Like a disk, it must be formatted before you can put files on it; also like a disk, it must be addressed by its volume name disk name or by its slot number. As with RAM, the computer can access the information on it very quickly. Also like RAM, what's stored on it is stored temporarily; when the power is turned off, the information on it is lost.

A RAM-Disk, Ramdisk or Ramdrive is a virtual solid state disk that uses a segment of active computer memory, RAM, as secondary storage, a role typically filled by hard drives. Access times are greatly improved, because RAM is approximately a million times faster than hard drives. However, the volatility of RAM means that data will be lost if power is lost, e.g. when the computer is turned off.
