Cheap, but not necessarily good, expandable, or resilient.
Although, I can tell you what not to do: a 45 drive SAS/2 or /3 4U JBOD case takes way too much power to use all the time and uses screaming 1U fans and PSUs by default.
I do have 45 drives in various XFS on md raid10 arrays. Don't even mention ZoL ZFS because that was a fucking disaster of undocumented, under-tested, and SoL "support" for something that should only be used on a proper Sun box like a Thumper. XFS and md are fairly bulletproof.
Perhaps one can Ceph their way into significant storage with a crap ton of tiny DIY boxes, but it's going to be a pain to deploy and manage, take lots of space, and probably damn expensive to physically install, network, and provide UPS for.
