For those of you with massive storage what kind of setup do you all have? This is mine: (24-bay one in the middle)
3 slots empty, recently added 8x 2TB drives in raid 10 but I ran into an issue with that array so it's not live yet. Oh, I don't really use the IBM ones below that. Those are "only" 400GB drives and 250GB ones. I might actually pull those out to make room for bitcoin mining rigs or something. Here is a full pic, it looks cool but those enclosures are so old and proprietary I don't feel they're worth leaving on or depending on them:
Once I get the raid 10 array working properly I'll have about 19TB or so. More than enough for my needs but if I need more I can upsize the raid 5 array to bigger drives as it's all 1TB drives right now and that array is actually what takes up the most slots.
I've actually been debating on playing around with btrfs, but I don't know if it's mature enough yet. Currently using md raid but I learned the hard way that raid 10's actually can't be expanded, only raid 5/6 it seems. There's 2 empty slots that I specifically left so I can add 2 more 3TB drives to my 4 disk raid 10, but it seems I wont be able to do that.
