DigiTimes writes helium HDDs could proper WD to the top spot in the enterprise HDD market. In the third quarter of 2012, WD had a marketshare of 45 percent in this market, versus Seagate's 48 percent.
"Helium HDDs could propel Western Digital to the top enterprise HDD spot, dethroning Seagate in the process," said Fang Zhang, analyst for storage systems at IHS. "Western Digital says helium-filled HDDs can reduce power consumption, an issue of concern for enterprise HDD users, by more than 20%. And helium-filled HDDs can advance drive capacity by another 25% to 50%, without increasing platter density or drive thickness."
Current drives using perpendicular magnetic recording technology support up to 4TB in capacity. Helium can extend that to 5TB or even 6TB. The weight or thickness of current HDD products can also be reduced by approximately 30% by stacking platters closer together.
