The World's Biggest Hard Drive Is Now Ten TB, Not Eight

If you thought 8 TB was plenty, think again. Western Digital just announced that it has added a 10 TB hard drive to its HelioSeal product line.

The drive, which hermetically seals helium in order to reduce internal friction and power use, runs about 5 degrees cooler than today's 7,200 rpm drives. Sealing air out of the drive also keeps humidity and other contaminants from getting in. By using helium instead of air, Western Digital was able to stack 7 platters and drastically reduce power usage, says Computer World.

This Is the World's First 8 TB Hard Drive

Bigger is better. Seagate just shipped the world's first 8 TB hard drives to "select customers", a new milestone for fitting gobs of data on a single 3.5-inch platter.

It's meant for enterprise customers — you know, corporate data centers and such — to create denser storage arrays for cloud content and backups, which is a shame. Between all the videos I've shot and all the pictures I've taken and all the high-quality music and movies I've downloaded for years, I could easily fill this baby up.


Unlike it's rival Western Digital, which uses helium to reduce friction in a spinning disk and increase its drive capacity by 50%, Seagate isn't saying how it managed to cram so much data on these hard drives. An article on Computer World speculates that Seagate is probably achieving this by using a technology called Shingled Magnetic Recording (SMR), which overlaps tracks on a platter like shingles on a roof. Seagate has said in the past that they can create 20 TB drives using SMR by 2020.

The hard drives will be widely available next quarter. If you're building something like a media-center-cum-home-server-cum-gaming-rig, you'll probably want to snag one of these. [Seagate]
