  2. List of Linux distributions that run from RAM - Wikipedia

    en.wikipedia.org/wiki/List_of_Linux...

    This ability allows them to be very fast, since reading and writing data from/to RAM is much faster than on a hard disk drive or solid-state drive. Many of these operating systems will load from a removable media such as a Live CD or a Live USB stick. A "frugal" install can also often be completed, allowing loading from a hard disk drive instead.

  3. Trim (computing) - Wikipedia

    en.wikipedia.org/wiki/Trim_(computing)

    The table below identifies each notable operating system and the first version supporting the command. Additionally, older solid-state drives designed before the addition of the TRIM command to the ATA standard will need firmware updates, otherwise the new command will be ignored. However, not every drive can be upgraded to support trimming.

  4. Memory paging - Wikipedia

    en.wikipedia.org/wiki/Memory_paging

    For simplicity, main memory is called "RAM" (an acronym of random-access memory) and secondary storage is called "disk" (a shorthand for hard disk drive, drum memory or solid-state drive, etc.), but as with many aspects of computing, the concepts are independent of the technology used.

  5. Foremost (software) - Wikipedia

    en.wikipedia.org/wiki/Foremost_(software)

    Foremost is designed to ignore the type of underlying filesystem and directly read and copy portions of the drive into the computer's memory. [3] It takes these portions one segment at a time, and using a process known as file carving searches this memory for a file header type that matches the ones found in Foremost's configuration file. [1]

  6. dm-cache - Wikipedia

    en.wikipedia.org/wiki/Dm-cache

    The design of dm-cache requires three physical storage devices for the creation of a single hybrid volume; dm-cache uses those storage devices to separately store actual data, cache data, and required metadata. Configurable operating modes and cache policies, with the latter in the form of separate modules, determine the way data caching is ...

  7. Disk buffer - Wikipedia

    en.wikipedia.org/wiki/Disk_buffer

    Modern hard disk drives come with 8 to 256 MiB of such memory, and solid-state drives come with up to 4 GB of cache memory. [2] Since the late 1980s, nearly all disks sold have embedded microcontrollers and either an ATA, Serial ATA, SCSI, or Fibre Channel interface. The drive circuitry usually has a small amount of memory, used to store the ...

  8. CAINE Linux - Wikipedia

    en.wikipedia.org/wiki/CAINE_Linux

    [3] [4] CAINE is a live Linux distribution so it can be booted from removable media (flash drive) or from an optical disk and run in memory. [5] It can also be installed onto a physical or virtual system. In Live mode, CAINE can operate on data storage objects without having to boot up a supporting operating system.

  9. Live CD - Wikipedia

    en.wikipedia.org/wiki/Live_CD

    Although some live CDs can load into memory to free the optical drive for other uses, loading the data from a CD-ROM is still slower than a typical hard drive boot, so this is rarely the default with large live CD images, but for smaller live CD images loading the filesystem directly into RAM can provide a significant performance boost, as RAM ...
