Western Digital subsidiary HGST has announced [hgst.com] the Ultrastar Archive Ha10, a 10 terabyte helium-filled shingled magnetic recording [wikipedia.org] (SMR) hard disk drive. It rotates at 7,200 RPM and has a 256MB cache [techgage.com].

HGST has also released libzbc [github.com], "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 [theregister.co.uk]. 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 [wikipedia.org]?
