Western Digital subsidiary HGST has announced the Ultrastar Archive Ha10, a 10 terabyte helium-filled shingled magnetic recording (SMR) hard disk drive. It rotates at 7,200 RPM and has a 256MB cache.
HGST has also released libzbc, "a simple library providing functions for manipulating disks supporting the Zoned Block Command (ZBC) and Zoned-device ATA command set (ZAC)."
The new drive is intended for enterprise bulk storage that is infrequently accessed. SMR tracks are partially overlapped which can hurt drive performance. The Ha10 has lower sequential write speeds than the He8. Seagate has already released 8 TB SMR drives.
What's next? 12 TB? 16 TB? HAMR?

Also, storing hydrogen in a metal container can lead to hydrogen embrittlement [wikipedia.org] as the gas slowly leaks out through the metal. Turns out, being the 1st element on the chart, the hydrogen atoms are really small and hard to contain (in gas form anyway).
