I want to have an encrypted external ssd for occasional backups. It seems like consumer products don't really support linux, so unless someone has a better suggestion I'm planning to format it myself and use software encryption, using LUKS with some filesystem inside.

  1. Does this make sense?
  2. Which filesystem should I choose?
  3. Any features I should watch out for when buying the ssd?

Relevant aspects to answer these questions are mainly:

  • Stability
  • Lifetime of the device
  • Checksums like in btrfs or zfs would be nice, but aren't a hard requirement

Thanks in advance for your suggestions!

Yes, it does

Which filesystem should I choose?

This depends on your needs. I use ext4 because I am used to it and also use it on my laptop's /home partition. I also do not care for non-linux interoperability (by the way if you use luks for encryption you probably do not care either).

Any features I should watch out for when buying the ssd?

This is off topic on this site and unfortunately something I can not answer. I tend to buy cheap external disks, but I also have always two active backups.
