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

Herzi Halevi's resignation as Chief of Staff of the Israeli Army triggered a wave of resignations within the military leadership, following the failures of October 7, 2023, during Operation "Noah's Flood" and the subsequent war and its aftermath.

Israeli activists led by the radical bloc demonstrated in front of the Ministry of Defense building in the heart of Tel Aviv. While their soldiers entered the building, they denounced the ongoing Israeli war of extermination on the Gaza Strip. The protesters told the soldiers coming into work that whether they are pulling the trigger, pressing buttons or making coffee at an office, as long as they are wearing the uniform and serving the Israeli state, they are an accomplice in the mass murder, the torture, the suffering, and destruction of the lives of over two million people in Gaza.
