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?

    You absolutely can. Of course you’ll only be able to use as much capacity as the smallest disk. Sometime ago I was running a secondary mirror with one 8TB disk and 3 disks pretending to be the other 8TB disk. They were 4TB, 3TB and a 1TB - trivial with LVM. Worked without a hitch for a few years till I replaced the three gnomes in a trench coat with another 8TB disk. Obviously that’s suboptimal but it works fine under certain loads.
