Launched at the same time as the 30TB IronWolf Pro, the 30TB Exos M is designed for use in cutting-edge cloud and enterprise environments and has a feature set that reflects this type of usage. We put it through its paces to find out what it can offer at the £600 asking price.

Seagate's Exos M is built on the company's Mozaic3+ technology, which makes use of HAMR (Heat-Assisted Magnetic Recording) to enable the 10 high areal density (3TB) discs the drive uses.
