Memory got cheaper, storage increased in capacity.

In my country for offline store purchase of USB HDD only 4Tb seagate variant available, thats 15000 in pur currency thats almost 1.5 month salary in private sector

Any higher size and have to import, and and forex applied, prices goes upto 4 0's , when i read people on youtube or blogs saying they rotate 15Tb and higher on their nas raids, that seems just dream for use never to fulfill
