Ramdisk or RAM-Disk is a virtual hard drive based on software abstraction that treats a segment of random access memory (RAM) as secondary storage which is similar to hard disks, except with advantage that ramdisk is a lot faster and access time is greatly improved. As there is no mechanical moving parts involved, there won’t be question of wear and tear too. Ramdisk has one obvious downside, that it’s volatile and not solid state. Contents in Ramdisk is stored in computer RAM, which will be lost when the power of computer is switched off.With these benefits and limit, ramdisk can be used to store frequently accessed yet less important temporary data to speed up the system performance, such as swap space for virtual memory, temporary files used for programs such as Internet Explorer, BT client, P2P eMule, compression utility, translation software and etc, frequently accessed data from a database or used to hold uncompressed programs for short periods. From privacy point of view, Ramdisk is also a working drive for decrypted version of encrypted document, as all trace of the data will be wiped and deleted once power off.
There are plenty of Ramdisk driver and software available, such as RamDisk9xME, RAMDiskXP, RAMDiskSE and RAMDiskVE from Cenatek, RamDisk and RamDisk Plus from SuperSpeed, RAMDisk Enterprise Lite and Full version plus 64 MB limited free RAMDiskbased on Microsoft Ramdisk below from QSoft, and Ramdisk.sys driver for Windows 2000 from Microsoft published under KB257405.
