This year, the amount of stored data will grow to 2.16 zettabytes worldwide, according to IDC. By 2016, it will have grown to 3.77 zettabytes. As remarkable as we are at creating data, storage technology has kept up.
Data storage is the fastest growing semiconductor technology going. Tape storage, hard disk drives and solid state storage capacities have generally doubled every 12 to 18 months.
Desktop drives today come in 4TB capacities (5TB later this year); That's enough to hold 1 million photos or 562 hours of high-definition video.
By 2020, Seagate believes heat-assisted magnetic recording (HAMR) will provide you with a 60TB desktop hard drive. That’s enough for 12 million photos or 6,750 hours of HD video.
