As unfortunate as that is this is not a universal problem, where I live 14/16/18/20 are readily available and competetive in price/TB, and they have been for a few years (at least the 14/16TB ones, not sure about 18/20). One would hope that the roll out of larger capacity drives would also result in more availability in your region - perhaps not of the largest capacity that exists, but at least of a larger capacity than is currently available to you.
When are we going to have 16 TB consumer HDD’s (excellent for backups or if you like having you’re own movie collection in high quality)?
All I can get where I live is 12 TB and there is limited availability and the prices are insane.
