Can I use two different drives?
I am building a NAS in RAID 1 (Mirror) mode. Should I buy 2 of the same drive from the same manufacturer? or does it not matter so much?

If you haven't looked into it, and if you already have the disks of varying capacity, check out JBOD. You will have to configure a system for backups however as you wont have parity like raid1
Raid is not a backup...
I'm aware, but raid 1 is mirroring which is redundancy, a jbod offers no redundancy so a backup would be even more crucial to protecting from data loss. Also i never said raid is a backup.
JBOD via mergerfs and snapraid on top for parity is a possible solution.
Any performance hit for that config, I've never heard of that setup before.
Don't know myself as I have no use case for that setup, but it is a well known setup since several years. If teh performance was bad it wouldn't be recommended as an alternative as often.
That's a solution i never knew existed, that's cool as hell.
Can't you just format jbod with zfs or some other raid solution? I'm sure it depends on hardware but it shouldn't be rocket science
