- List_of_RAM_drive_software abstract "RAM drive software allows part of a computer's RAM (memory) to be seen as if it were a disk drive, with volume name and, if supported by the operating system, drive letter. A RAM drive has much faster read and write access than a hard drive with rotating platters, and is volatile, being destroyed with its contents when a computer is shut down or crashes—volatility is an advantage if security requires sensitive data to not be stored permanently, and to prevent accumulation of obsolete temporary data, but disadvantageous where a drive is used for faster processing of needed data. Data can be copied between conventional mass storage and a RAM drive to preserve it on power-down and load it on start-up.The main reason for using a RAM disk is to allow the use of physical memory that is 'inaccessible' to the Operating System - specifically the 760 MB or so in the 3.25 GB–4 GB 'gap' that 32-bit Windows XP refuses to use and any physical memory above the 4 GB address 'barrier' that is also not recognised by non-Server 32-bit versions of Windows XP. To make use of this memory, the usual approach is to set it up as part of the Windows 'swap file' Virtual memory space.Features that vary from one package to another: Some RAM drives automatically back up contents on normal mass storage on power-down, and load them when the computer is started. If this functionality is not provided, contents can always be preserved by start-up and close-down scripts, or manually if the operator remembers to do so. Some software allows several RAM drives to be created, other programs support only one. Some RAM drives when used with 32-bit operating systems (particularly 32-bit Microsoft Windows) on computers with IBM PC architecture allow memory above the 4 GB point in the memory map, if present, to be used; this memory is unmanaged and not normally accessible. Software using unmanaged memory can cause stability problems.Some RAM drives are able to use any 'unmanaged' or 'invisible' RAM below 4 GB in the memory map (known as the 3 GB barrier) i.e. RAM in the 'PCI hole'. Note: Do not assume that RAM drives supporting 'AWE' (or Address Windowing Extensions) memory above 4 GB will also support unmanaged PAE (or Physical Address Extension) memory below 4 GB—most don't.A few RAM drives allow the virtual drive to be used as the system swap file. This is a great way to utilize rarely-used memory and speed up MS Windows.↑ ↑ 2.0 2.1 2.2".
