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

China’s Shadow Intel Market Is Selling the Iran War Back to Washington
Chinese firms are turning the Iran war into a commercial product: satellite mosaics, carrier tracking, airbase maps, and slick AI analysis branded as “exposing” U.S. forces. Beijing can keep its official distance while private companies do the dirty work in public.
That is the real threat here. Even if some of the firms are overstating what they can see, the model still matters: open-source data, machine learning, and military-linked firms can package U.S. movements fast enough to hand adversaries a usable picture of the battlefield.
The Washington Post notes that some firms have links to the PLA, while U.S. lawmakers are already treating the trend as a live security problem, not a theoretical one. That fits Beijing’s larger playbook: private-sector deniability outside, strategic benefit inside.
So the war is no longer just being fought with missiles and drones. It is also being priced, mapped, and resold by companies that treat an American deployment as a market opportunity.
