Which Drive Has What?

Our drives are purpose-built, meaning each of our internal drives are built specifically for their intended use. Each drive has been optimised, tested, and approved by various technology partners to meet and exceed the requirements for its application in terms of reliability, performance and quality. Seagate drives utilise conventional magnetic recording and shingled magnetic recording technologies based on intended use. Below is a table of our internal drives with each of their respective recording technology.

Mozaic 3+: Where the Future is Read and Written


Mozaic 3+ is a hard drive platform that incorporates Seagate’s unique implementation of heat-assisted magnetic recording (HAMR) technology to deliver mass-capacity storage at unprecedented areal densities of 3 TB/disk and beyond.
 
Mozaic 3+ is a composite of the most complex nanoscale recording technologies and material science breakthroughs on the planet and is how data can now be stored to media at density levels that were previously inconceivable, all while using the same material resources as current Seagate hard drives and delivered in a known 3.5-inch form factor. Mozaic 3+ is both the present and future, with an eye toward 50 TB and still “10 platters and 20 heads”.
 
With Mozaic 3+, data centre operators can store more exabytes in less space, with fewer racks, amounting to massive TCO savings, with energy consumed and floor space.
