Western Digital just announced the largest mechanical hard drive in the industry, a 15TB helium-sealed monster. Designed for data centers and cloud storage services, the 15TB HDD is intended for enterprise customers in need of densely compacted, reliable storage. Pricing and availability haven't been announced, but don't expect the drives to come cheap.
Sam Medley,

Need a lot of storage space but don’t have a lot of physical space? Western Digital has your back with its new 15TB mechanical HDD, announced earlier this week.

When released, the 15TB Ultrastar DC HC620 will be the highest capacity drive on the market, replacing Western Digital’s own 14 TB drive they released in April. The drive is designed for cloud storage and data center services. Western Digital said that the drive should be able to meet the needs of “large video surveillance ‘smart city’ initiatives, storage for regulatory compliance and Big Data storage.”

Western Digital built the drive using HelioSeal technology, which uses helium to increase the number of physical platters sealed within a drive. As it is less dense, helium allows platters to be stacked closer together and reduces friction and strain when the platters spin. As a result, more drive platters can be stacked on top of each other, and the platters should last longer while using less energy.

Pricing has yet to be announced, as has a release date. However, based on the price of WD’s 14TB data center drive, don’t expect the largest HDD in the industry to come cheap. Considering the relatively high cost of running a data center, that shouldn’t come as a surprise to most enterprise customers.

I've been a "tech-head" my entire life. After graduating college with a degree in Mathematics, I worked in finance and banking a few years before taking a job as a Systems Analyst for my local school district. I started working with Notebookcheck in October of 2016 and have enjoyed writing news articles and notebook reviews. My areas of interest include the business side of technology, retro gaming, Linux, and innovative gadgets. When I'm not hunched over an electronic device or writing code for a new database, I'm either outside with my family, playing a decade-old video game, or sitting behind a drum set.
