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

🪐 In the constellation Ophiuchus, the asteroid 101955 Bennu harbors boulders on its surface that are actually fragments from a much larger parent asteroid, dislodged by ancient cosmic impacts. Analysis of samples returned by NASA’s OSIRIS-REx mission revealed minerals that interacted with liquid water billions of years ago, revealing Bennu as a time capsule from the dawn of the solar system. ✨

🪐 One of the most intriguing potentially hazardous asteroids is (101955) Bennu, a 500-meter-wide space rock that approaches Earth every six years. Bennu's orbit is so well-studied that NASA sent the OSIRIS-REx mission to collect samples, as even small forces—like sunlight changing its spin—can alter its path, making Bennu a prime real-world example of why scientists keep a close watch on these cosmic wanderers. ✨

🪐A skyscraper-sized space rock is on its way past Earth.
On September 18, 2025, asteroid 2025 FA22, measuring up to 300 meters across, will sweep by our planet. At its closest, it will be about 835,000 km away — more than twice the distance to the Moon.
Moving at a breathtaking 34,000 km/h, this Apollo-type asteroid silently follows its orbit around the Sun, crossing Earth’s path in space. The flyby will peak around 07:41 UTC, a moment astronomers worldwide are watching closely.
Massive, fast, and ancient — yet passing safely by. Encounters like this remind us how close cosmic giants can come, while still leaving Earth untouched. ✨

🪐 The asteroid Bennu, about 500 meters wide, orbits the Sun and regularly passes close to Earth—so close that it’s classified as a “potentially hazardous asteroid.” Scientists continually monitor Bennu’s path because even small shifts caused by sunlight (known as the Yarkovsky effect) could alter its future trajectory, making it one of the most closely watched objects to help protect our planet from possible impacts. ✨

🪐 One of the closest ongoing space threats to Earth is asteroid (101955) Bennu, a 500-meter-wide rock whose orbit brings it near our planet about every six years. Bennu's path is carefully tracked because even small gravitational nudges or sunlight (the Yarkovsky effect, where heat causes tiny pushes) could change its future route, making it a real-world example of why scientists keep a vigilant watch on these near-Earth objects. ✨
