Hi everyone! I have a Dell Inspiron 5570 laptop with 1TB HDD and 16 GiB
RAM (it supports 32 GiB). I am about to buy an M.2 NVMe 250GB SSD---a
Western Digital WD Blue SN550. I would like to set the system for
reliability, SSD durability¹ and performance.
I have looked at [Multi HDD/SSD Partitioning Scheme][] but it is too
complex and probably outdated (last modified 2013-10-17). I would like
something simpler. For backups, I would continue my weekly manual
backups to my 1.5 TB external HDD with duplicity.
On the SSD I intend to leave 35 GB unpartitioned for extra over
provisioning. It would have just one 215 GB partition.
On the HDD I would put a 34 GB swap partition at the beginning, then a
215 GB partition for RAID1 with the SSD, then a 751 GB partition. I
intend to put Debian system *and* /home on the 215 GB RAID1, but I would
set all the XDG user dirs² on the 751 GB HDD partition. I would have
tmpfs on /tmp---I have read that long thread where someone alleged that
moving /tmp to tmpfs makes it useless but I disagree.
Would all this be reasonable? Do you recommend any change? Any tip? I
run Debian stable with only official repositories, including
bullseye-backports. I also manually installed GNU Guix package manager
and my main Guix profile has 163 packages.
Regards!

¹ According to its data sheet, the 250GB WD Blue SN550 endures 150TBW.
² See the xdg-user-dir manpage.
Regarding the swap space: I wouldn't make it so big. That really isn't
necessary. I have a 64GB RAM system here, on which I have 2GB of swap. I
doubt I have ever seen conky show me more than 35% use. And I am quite a
heavy user of system resources (much 3D CAD editing, photo editing,
video editing and rendering, and often multiple VM's in use).
My laptop has 32GB of RAM and 2 GB of swap and on that system I haven't
seen much swapping either.
