The idea behind tmpfs is similar in concept to a RAM disk, in that both provide a file system stored in volatile memory; however, the implementations are different. While tmpfs is implemented at the logical file system layer, a RAM disk is implemented at the physical file system layer. In other words, a RAM disk is a virtual block device with a ...
Tiny Core Linux is an example of Linux distribution that run from RAM. This is a list of Linux distributions that can be run entirely from a computer's RAM, meaning that once the OS has been loaded to the RAM, the media it was loaded from can be completely removed, and the distribution will run the PC through the RAM only.
zram, formerly called compcache, is a Linux kernel module for creating a compressed block device in RAM, i.e. a RAM disk with on-the-fly disk compression. The block device created with zram can then be used for swap or as general-purpose RAM disk. The two most common uses for zram are for the storage of temporary files (/tmp) and as a swap ...
An affordable RAM Disk compatible with all Windows Workstation and Server OS versions (32- and 64-bit) starting from Windows 2000. 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.
The shareware version appeared on Fred Fish Disks 58 [5] and 241. [6] AmigaOS itself would gain a Recoverable Ram Disk (called "RAD") in version 1.3. [7] Many Unix and Unix-like systems provide some form of RAM drive functionality, such as /dev/ram on Linux, or md(4) [8] on FreeBSD. RAM drives are particularly useful in high-performance, low ...
In Linux systems, initrd (initial ramdisk) is a scheme for loading a temporary root file system into memory, to be used as part of the Linux startup process. initrd and initramfs (from INITial RAM File System) refer to two different methods of achieving this.
Increasingly, memory-based solutions for the temporary directory or folder are being used, such as "RAM disks" set up in random-access memory or the shared-memory device /dev/shm in Linux. A Flash -based solid-state drive is less suitable as a temporary-storage device for reading and writing due to the asymmetric read/write duration and due to ...
It is required, however, for the boot partition (i.e., the drive containing the Windows directory) to have a page file on it if the system is configured to write either kernel or full memory dumps after a Blue Screen of Death. Windows uses the paging file as temporary storage for the memory dump.
