Researchers have discovered that a pinch of table salt can get more data onto spinning hard drive platters. A lot more: 6 TB in a single platter!
Considering the latest drives have up to 5 platters, that would be 30 TB in a single hard drive. Put 45 of those drives into a Backblaze Storage Pod and you would store 1.35 petabytes (!) in a single storage pod; more than 10 petabytes in a single rack.
Hello, Big Data. Meet your best friend, Salt.
