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

Donald Trump bragged that the U.S. is spending so much money on his war in Iran it has no funds to pay for daycare or healthcare. 💰⚔️
The 79-year-old president made the boast during a typically rambling speech while hosting an Easter lunch at the White House on Wednesday. 🦅🍽
“The United States can’t take care of daycare. That has to be up to a state,” Trump said. “We’re a big country. We have 50 states. We have all these other people, we’re fighting wars. We can’t take care of daycare. You’ve got to let a state take care of daycare, and they should pay for it too.” 🏛💼
“Medicaid, Medicare, all these individual things. They can do it on a state basis. You can’t do it on a federal [level]. We have to take care of one thing: military protection—we have to guard the country. But all these little things, all these little scams that have taken place, you have to let states take care of them.” 🎖🛡
