PSA: RAM Disks are amazing.

So, I've just discovered something which I haven't really thought of before-- RAM disks.
Pretty self explanatory, a disk which uses RAM.

Obviously SSDs are fast but HOLY FUCK THIS IS BEAUTIFUL!!
IT IS INSTANT-FUCKING-TANIOUS.
Imagine an SSD stuffed with caffeine and then given steroids. It is wonderful.

If you spare RAM I must recommend you at least try it:

    @Gregozor2121 I haven't looked into it recently, but I'm fairly certain it would be on par (or close) to the latest NVMe M.2 SSD that have average read/write speeds of 3,400 Mb/s and 2,500 Mb/s.

    DDR4 is far faster, 17GB/s (Bytes not Bits) at its slowest.
    (136 000Mb/s)

    @24th-Dragon Yes, as far as I know this works by first copying all required files from the actual harddrive/SSD after boot, and then the stuff stays in RAM until you shutdown.

    So basically you force it to keep stuff you deem important in RAM.

    You dont use it for storage but for performance increase. They have to use normal hdds for ssd to save data permamently

    @irene told me about tmpfs long ago, it's a similar concept, and bloody fast, been using it heavily.

    @deadlyRants so, basically forced caching? or am i completely off track here?

    This is nothing new? initramfs?
    Puppy linux has used them forever, too.

    They even exist in Windows lol

    I had a RAM disk on my Atari ST, and the DOS crowd had something similar with config.sys hackery. That was before 42% of the DR members were even born.

    Yeah RAM disks have been around for a long time. If you think about it, they’re the logical inverse of virtual memory: one is using hard disk to give you additional working memory, the other is using memory to give you super fast “storage”.

    There’s also memory-mapped files which are similar but act by mirroring files in memory.

    @irene it also saves the sd card in your raspberry
