From InfoWorld: Western Digital has 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-inch 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 816Gb per square inch.
The new HDD represents a 25 percent increase in capacity over the previous generation 8TB Ultrastar He8 HDD and uses 56 percent less watts/TB than traditional air-filled HDDs. The drive uses as little as 0.5 watts per terabyte while idle; the SATA model uses 6.8 watts while operating and the SAS model uses 9.5 watts while spinning, which is still 56 percent less power than the previous generation, WD said.
The Ultrastar He10 also boasts a 2.5 million mean-time-between-failures (MBTF) rating as well as a five-year warranty.
