I want to use my old desktop as a home storage server, I have one 8tb drive right now that has the majority of my data on it, I want to buy two more 8tb drives and run raid 5 so I have approx 16 tb of space and a parity drive (I know I am not actually gonna have 16tb but im using easy numbers). Anyways can I set up the RAID 5 with my drive that already has data on it without losing it all or do I have to buy 3 new drives and then transfer the current 8tb contents over after building it? The drive I have is only 6 months old so I would prefer to just buy 2 more but if thats not an option than I guess Ill just add it in afterwards and have 24ish tb of storage

No, you'll have to build the array from scratch.

Also not possible. I'm not aware of any RAID5 implementation that allows for expansion like that.

What are you going to use to create the RAID array?

 

Hardware RAID cards support RAID level/type migrations so you could create an initial RAID 0 of 2 disks then move the data to it, add the old disk and then migrate the array to a RAID 5. However there are few, to none I know of, software RAID implementations that allow this equivalent function. Also fair warning I can't remember if migrating from RAID 0 to RAID 5 is supported either, I've only done RAID 1 to RAID 5 and RAID 5 to RAID 6 etc
