dn7172 Posted November 2, 2020 Share Posted November 2, 2020 Up to now, my experience with unraid has been with one parity drive, but I'm looking to increase that to two. I just have a couple questions that I like to answer before I decide on the type of drive to purchase. I'm undecided on what type of drive to use for parity. I just read somewhere that it's a waste to use a Red drive for parity, is this true? That is, is it better to use green drives over red (and even blue)? To run two parity drives, do each one have to be as large as the largest data drive like it is when running with one or can they be split? For example, if my largest data drive is 4TB, can each of the parity drives be 2TB? I have a feeling the answer is they both need to be 4TB but looking for confirmation. Thanks Quote Link to comment

Parity should be the same as the other drives on the server, just avoid SMR drives. 8 hours ago, dn7172 said: To run two parity drives, do each one have to be as large as the largest data drive This Quote Link to comment
