I put 24 4tB Hitachi Ultrastars in them about 5-6 years ago. Have them setup as a RAID10, so only 48TB available storage, but if bought today, 6TB disks might be better buy.
Someone else will probably have to write the code, but I've been thinking about spec'ing a raid-60 or 61 mode for md-raid. 24 drives would make sense as 3 8-drive raid-6, so you'd have 18 data disks and 6 parity disks. But this is a mode like linux raid-10 (which is *not* raid-1+0), so your data and parity would be scattered over all 24 drives. The important point of this is that if a drive fails, it gets rebuilt from all the other drives, and doesn't hammer just a few of them. If that sounds like a good idea, I'm told it's probably only a minor mod to implement it ...
