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