[QUOTE="SeriousHoax, post: 1102646, member: 78686"] Yeah, you can use both in the same PC no problem. I have both installed and use them. I heard about Nala but never really checked it. This is really wonderful. Looks like a child of Pacman and DNF but prettier 😃 The thing I talked about is different from TRIM. I looked into this matter a bit today and it seems ext4 kind of writes the same data twice. First into its journal before writing to the actual location. Write-ahead logging seems to the name of this method. So, this ensures highest quality of data integrity and can be recovered easily in case of data corruption. But this journaling feature also means there would be more disk space occupied. Probably this twice the amount of data writes doesn't exactly result in twice the amount of disk writes bytes. They must have some optimization to minimize that. BTRFS on the other hand has copy-on-write feature. Instead of journaling, they keep the old data and write new data on the empty sectors of the disk. This could also result in more space being occupied on this disk but mainly if snapshot feature is used. So, it has the ability to apply compression to reduce those extra occupied disk space. Anyway, my understanding of this is still not clear so I could be wrong about a thing or two. [/QUOTE]
