Currently running a home desktop with 6 different internal drives holding about 20 tb of personal media (home photos, videos) spread across them. No raid. Online backup w/backblaze and local with external drive.
I like this stup b/c being local, I can do inexpensive backup with backblaze. But organizing across them is a pain and not fault/drive failure tolerance like raid would have.
I'm running out of space and wondering best upgrade path. Do I just replace oldest/smallest with larger, new drives and keep same strategy? Can I do raid internally and still get regular backblaze service?
I've considered a NAS but not sure I see a lot of upside in terms of value if I have to pay by the tb for online b/up and buy multiple new drives to start it.
Any downside to staying local with a few large drives in the box?
