It is a lot like the pets vs cattle comparison. If your underlying structure can tolerate larger amounts of downtime the extra cost of enterprise equipment. For many applications it is easier to buy more expensive hardware that has exceptional uptime than it is to hire people to rewrite and take advantage of cloud based options. Enterprise hard drives use SAS connectors to allow redundant paths and a full scsi command set. Enterprise hard drives have a bit error rate an entire order of magnitude better than consumer hard drives. The rated powered on hours and mean time between failure will be better, but not more cost effective with enterprise gear unless you take into account the labor cost and downtime cost of replacing that hardware.
