I always thought you’re supposed to buy similar drives so the performance is better for some reason (I guess the same logic as when picking RAM?) but this thread is changing my mind, I guess it doesn’t matter after all👀
I usually find the cheapest drives and buy multiple of those, but you should be able to assemble a RAID out of different disks, though you’ll be limited to the space of the smallest one in the mirror set.
Also make sure that your RAID systems supports this.
You can use different manufacturers, just make sure they are the SAME size and speed. You can also get the same ones from the same vendor, just from different online shops to try and offset getting a bad batch.
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
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.

Hardware or software (BTFRS, ZFS etc…) RAID?
Software

Okay. Where do you buy the disks?
Ebay. If you’re outside the US, you’ll probably be better off with a more local site.

Raid is not a backup…
