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.Īll created RAM disks can be accessed from the /dev/ramdisk directory path and treated like any other block device that is, accessed like a physical block device, labeled with a file system and mounted, to even used in a ZFS pool.
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.
By storing files and programs into memory, you can speed up internet load times and disk-to-disk activities, accelerate databases. It creates a virtual RAM drive, or block of memory, which your computer treats as if it were a disk drive. RAMDisk is Freeware (up to 1GB disk size).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.
