For example, take the Samsun PM836 SSDs. They go up to 4TB per SSD right now. They aren't cheap, but the price per I/O is low. Spinning disks are cheap with storage, but very expensive per I/O.

MONs on dedicated hardware, OSDs and the same with RGW and CephFS MDS servers. It is not a requirement persé, but it makes things easier to run.
