NewEgg has more Seagate hard disks but the prices are now $40 higher than before. The 8TB disks used to be $209 so now the price is $259. The usual Chia mining is the usual scapegoat.
Usually disks get cheaper over time. This is an example of illegal pricing by Seagate and/or NewEgg.
At present there is adequate storage for games. At present there is one 8TB disk that is unallocated which stands ready.
