I would like to install a Linux distribution (probably Devuan) on my dual SSD system, in the most convenient way:
- 250GB, NVMe.
- 500GB, SATA3.
The criteria are both performance and SSD lifespan (giving the priority to the NVMe one).
- Which directories of Linux require the best performance, and which ones are not critical?
- Which directories are (mostly) accessed in read mode, and which ones in read/write mode?
- Considering I have 24GB of RAM, where had the /tmp directory better be located? NVMe, SATA3 or RAM-disk? Had anything else better stay on the RAM-disk?
- Should directories which are entirely loaded in memory (e.g. the kernel) not have any performance impact after boot?
The system is a laptop used mainly for development.
Could this be a good distribution?
- Fast & small drive:
/, /etc, /bin, /sbin, /lib, /lib64, /usr, /boot, /root, /sys, /home?, /opt?
- Large & slow drive:
/media, /mnt, /lost+found, /var, /home?, /srv
- RAM disk:
/tmp, /run, /var/run, /var/cache?, /var/spool?
- Kernel provided:
