В Linux стандартными средствами можно использовать часть оперативной памяти как диск. Для этого требуется указать тип монтирования tmpfs в команде mount
mount -t tmpfs -o size=5G tmpfs /mnt/ram
Теперь путь /mnt/ram можно использовать как обычный каталог. Для чего это может быть нужно?
▫️ Скорость работы с таким каталогом выше чем многие SSD и тем более HDD.
▫️ Если у вас очень быстрый SSD на NVMe M.2 то такой способ особо не прибавит вам скорости, но поможет сохранить ресурс SSD когда требуется обрабатывать очень много мелких файлов и оперативка позволяет выделить нужный объем.
▫️ Оперативка это энергозависимая память, поэтому выключении питания все файлы безвозвратно теряются. Такой "non persistent" каталог гарантирует удаление временных файлов.
Я написал небольшой скрипт для условного теста и сравнения скорости копирования файлов между SSD и RAM.
Вот мои результаты:
Single File Size: 30.0Gb
ssd > ssd: 0:00:12.850 / 2.3Gb/s
sdd > ram: 0:00:06.453 / 4.6Gb/s
ram > ram: 0:00:06.995 / 4.3Gb/s
ram > sdd: 0:00:06.217 / 4.8Gb/s
Dir size: 32.7Gb, File count: 11127
ssd > ssd: 0:00:15.063 / 2.2Gb/s
sdd > ram: 0:00:08.486 / 3.9Gb/s
ram > ram: 0:00:08.032 / 4.1Gb/s
ram > sdd: 0:00:07.026 / 4.7Gb/s
Скрипт для теста ↗️
На моём железе прирост скорости ~2x. Плюс экономия ресурса SSD.
В Windows такой фишки по умолчанию нет, но обязательно найдутся аналогичные решения

Why am i so addled, i seek retort through this creation.
Can't understand a thing, anymore. I just need Salvation
What am i gonna gain, if anything, why do i need revelation.
I do just fine without mass, getting back to isolation?
Why is it so important, why look for identification?
Is it the curiosity or the fear of seperation?
There is inspiration, there is recreation, there is manipulation, sensation, violation & frustration but is there anything that's necessary? Is there any elevation?
I know it bothers none but please, tell me, where am i heading to, what is my destination?

I mutilate myself, no matter what i do.
Acting all spirit, i maim when I'm disregarded, when I'm passed over.
Acting all foul isn't my cup of tea either, i maim again, i incapacitate either way.
Being ignoble and or moral, both roads are noxious to me. What do i fancy then?
You blemish me, your bygones. I can't condone it. I can't strand you either. You, your, it impedes me, candidly but won't gash you by disclaim, renounce.... Won't? Well, can't is more apt, can't bestow to soar your agony.... But about my torment? I have nowhere to go, no door left open, I'm stuck, stuck with you. I'll dwell, I'll persist, that's what I've been doing, that's what i can keep up with. No possibility, either at whim or reluctantly, i have to adhere, no recourse.... I'd be thrusting here, i don't know the stretch, the extent, maybe perpetuity.

You were fire, i wasn't ice
I was supposed to but it wasn't nice
I was magma that was piquant
Why was our bond so highly turbulent?
The violent gesticulation of air around your flames
Wasn't any good for my fever but i got used to the games
We were bonded the way we weren't meant to be
Was it destiny, i wondered or was it our will that was the key
You're no good for me, i know, said she
But it was too late for her to be set in the world again like a bird, free
If we're meant to do it together, yes my love, we suffer like the way we suffered
You'd be the flame of my candle that demolishes my wax, he uttered
Afterall, diamonds dice diamonds, they are suited together
Shouldn't be befuddled with types different but stay where they belong, forever
