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?

...hdd with multiple read heads, at leas 2.
I have a seagate "backup plus" 2.5" hdd with 2 Terabytes...
In 3.5" hdd one could stack 3 such drives, thus 6 TB of these small plates + enought place for 2 arms.
In a 5" case, like the cdrom, i could imagine 4 arms around the plates...
Personally, i dont like ssd:s, there is plenty more room for imporvements in hdd:s...
