Seagate IronWolf 10TB HDD review

Built on a standard 3.5in format, the 10TB IronWolf has a spindle speed of 7,200rpm and 256MB of cache.
The drive uses helium technology and to get to its huge capacity it uses 7 PMR (Perpendicular Magnetic Recording) high capacity discs and has 14 reading heads.

Using helium (which is 1/7th the density of air) allows drive manufacturers to use thinner platters and be able to pack more of them into a drive chassis. This because using helium inside the drive reduces the drag force acting on the spinning disks as well as reducing flow forces acting around both disks and heads.
