Caching when watching a movie on Linux?

Question

linux

Good afternoon. Ubuntu is installed on an ssd drive on my home computer. I use the MPV video player to watch movies. All films are on another disk. When watching movies from another disk, the line Cached: + 150mb appears in the player. I understand that he constantly caches the movie on the SSD drive. And frequent writing to disks is not very good for it. Actually the question is: to score on caching movies and watch them from another disk, or before watching, throw off 11GB on an SSD and watch from there. Thanks in advance.

Answer 1

It's probably about the cache in memory. It is not clear on what basis the player, reading from one file, would write something to another. And where should I write to /tmp in /var/cache or /home/user ? But after all, this path may end up on the same section from which he reads the movie, what then is the point in such a "cache"?

Answer 2

Cached in RAM
