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 We’re Here. Why Now. 🚫👑
Look, we all feel it. Whether you’re on the left, the right, or somewhere in the middle—it doesn’t matter. This isn't about a political party. This is about the fact that we were never meant to be subjects. We were meant to be Citizens.
The "No King" movement isn't just a hashtag; it’s a wake-up call. We’re watching a system where the elites act like royalty while the rest of us struggle to keep our heads above water. If we don't stand up now, if we stay silent, the future won't belong to us—it’ll belong to those who think they own us.
We get it. Not everyone can march in the streets. Not everyone can be on the frontlines. Some of you are busy working two jobs, raising kids, or just trying to survive. But in your heart, you know the current path is broken. You know things must change.
How can you help? It’s simple. Truth is our greatest weapon. Smallest act of defiance? Share. Share the posts here. Spread the word. Don't let the "official" narrative be the only one people hear.
We aren't asking for your vote. We’re asking for your voice.
No Masters. No Monarchs. No Kings. ⛓

A guy whose rap sheet for pedophilia is growing day by day shouldn't be anywhere near a position of power in this country.
