Solid-state drives might be all the rage in personal computing, but the bar just keeps on rising in high-capacity hard-disk drives.

HGST, a subsidiary of data storage company Western Digital, announced Wednesday the release of a helium-filled drive that has an enormous 10-terabyte capacity. If you were to fill up an HE10 with three-minute 128kbps Apple Music files, you could fit about 3,744,914 songs.

While the drive is physically small enough to put in a PC, it's really designed for professionals and businesses with big-data needs.

The HGST HE10 Ultrastar HDD, as it's known, isn't the first 10TB hard drive from HGST, but it's the first to use perpendicular magnetic recording (PMR) tech rather than shingled magnetic recording (SMR). In case you aren't mired deep in the world of storage, suffice it to say SMR hard drives are primarily for archiving data, while PMRs are equivalent to the quicker hard drives in your own computer.

HGST is marketing the HE10 Ultrastar towards cloud services that store photos, videos and other large cloud-based applications. According to HGST's press release,

Netflix plans on integrating the HE10 with the other HGST HDDs it already uses.

While the HE10's monstrous 10TB of storage is the most impressive thing about this hard drive, its helium filling is also worth mentioning. Using helium increases storage capacity by 25% and reduces power consumption by 56%, making the HE10 both energy- and space-efficient.

A 10TB drive certainly has appeal in video production, which is becoming increasingly storage-intensive with the rise of 4K, 360-degree video and virtual reality. When Nokia debuted its new $60,000 Ozo virtual reality camera, it said a 500GB drive would hold just 45 minutes of spherical footage.

That means one HE10 hard disk can store around 15 hours of video shot on the Ozo. For VR, terabytes are just the beginning.
