RAM drivesoftware 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.
AMD Radeon™ RAMDisk is designed to work with any AMD or Intel-based platform with at least 512MB RAM and can be created using system RAM not already assigned to the O/S. Although RAMDisk is software, Windows Management treats it as a Hard Disk Drive. AMD Radeon RAMDisk is available in free versions (RAM drive up to 4 GB, or 6 GB with AMD memory), and commercial versions for drives up to 64 GB. The free version is 'advertising supported'. Creates only a single drive (does not support multiple RAM drives). Can be backed up periodically to hard drive, and automatically loaded when the computer.
01 – Dataram RAMDisk 1GB Free 32GB USD15 64GB USD20. What is RAMDisk? AMD Radeon RAMDisk AMD. The more RAM your computer has, the larger the RAMDisk you can create. For users that have more than 8GB of RAM in their computer and would like to utilize that memory for RAMDisk, license keys are available for purchase at various increments — up to 12GB, up to 24GB, up to 32GB and up to 64GB.
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.
md - memory disk
This driver provides support for four kinds of memory backed virtual disks: malloc, preload, vnode, swap. Disks may be created with the next command line tools: mdconfig and mdmfs. An example of how to use these programs follows.

Modern Linux systems come pre-installed with a user-accessible ramdisk mounted at
RapidDisk is a free and open source project containing a Linux kernel module and administration utility that functions similar to the Ramdiskadm of the Solaris (operating system). With the rxadm utility, the user is capable of dynamically attaching, removing, and resizing RAM disk volumes and treat them like any other block device.
tmpfs and ramfs
An example of how to use tmpfs and ramfs in a Linux environment is as follows:
Once the mount point is identified the mount command can be used to mount a tmpfs and ramfs file system on top of that mount point:
Now each time /var/ramdisk is accessed all reads and writes will be coming directly from memory.
Amd Ramdisk Free
There are 2 differences between tmpfs and ramfs.
1) the mounted space of ramfs is theorically infinite, as ramfs will grow if needed, which can easily cause system lockup or crash for using up all available memory, or start heavy swapping to free up more memory for the ramfs. For this reason limiting the size of a ramfs area can be recommendable.
2) tmpfs is backed by the computer's swap space
There are also many 'wrappers' for the RAM disks for Linux as Profile-sync-daemon (psd) and many others allowing users to utilize RAM disk for desktop application speedup moving intensive IO for caches into RAM.

QSOFT ( WinRamTech ) Ramdisk Enterprise
A RAM Disk compatible with all Windows Workstation and Server OS versions (32- and 64-bit) starting from Windows 2000. Prices vary from $9 to $11. The content of the RAM Disk can be made 'persisted' i.e. saved to an image file on the hard disk at regular times and/or at shutdown, and restored from the same image file at boot time. Because of the built-in disk format routines and the built-in load of the image file, this ramdisk drive is already fully accessible at the bootstage where Services and automatically started programs are launched. Certain concurrent running benchmarks of two ramdisks at the same time reveal that this ramdisk is almost the fastest version. A fresh full-featured evaluation version is provided every year around August and allows users to update their nearly expiring version. Although the development of this RAM Disk was ended on 2017 the ramdisk version 18.104.22.168 may still be purchased.

Microsoft provides source code for a RAM disk driver for Windows 7 and 8 
Windows also has a rough analog to tmpfs in the form of 'temporary files'. Files created with both FILE_ATTRIBUTE_TEMPORARY and FILE_FLAG_DELETE_ON_CLOSE are held in memory and only written to disk if the system experiences high memory pressure. In this way they behave like tmpfs, except the files are written to the specified path during low memory situations, rather than to swap space. This technique is often used by servers along with TransmitFile to render content to a buffer before sending to the client.
