Western Digital today announced the first 10TB hard disk drive (HDD) based on its HelioSeal Platform, which hermetically seals helium gas in the drive to decrease friction.

The new 3.5-in. Ultrastar He10 HDD is based on WD’s third-generation HelioSeal Platform, which also consumes less power per terabyte of capacity than any previous drive the company has shipped.

Besides being filled with helium, the new HDD uses typical perpendicular magnetic recording (PMR) to fit 10TB of capacity on seven platters with an areal density of 816Gbits per square inch.
