I work with an academic HPC group, and because researchers generally pay only for the hardware, and maybe some recharge rate for occasional maintenance, the cost per TB per month for 100's of TB and larger systems works out to the same for Glacier Deep (about $1/TB/mo) - except there is no 180 day requirement, no egress fees, and no transfer fees. And disk just keeps getting cheaper.

I'm told that big part of the solution is their use of ZFS.
