Seagate has announced a 14 terabyte helium-filled hard drive that uses perpendicular magnetic recording (PMR) rather than shingled magnetic recording (SMR). Toshiba announced a similar drive in December:
Seagate this week formally introduced its first hard drive with 14 TB capacity aimed at cloud datacenters that does not use shingled magnetic recording. The new Exos X14 HDDs are filed with helium and are based on the latest-generation PMR (perpendicular magnetic recording) platters, running at 7200 RPM.
[...] The Exos X14 is Seagate's response to Toshiba's MG07ACA HDD with 14 TB capacity announced last year, although until we recieve further information, we cannot do a direct comparison. The major benefit of both drives is their increased capacity that enables datacenter operators to store 3360 TB of data per rack (compared to 2440 TB with 10 TB HDDs), which is a key advantage for companies that need to maximize their storage capacity per square meter and per watt, while meeting other TCO objectives. Another indisputable win of 14 TB hard disks from Seagate and Toshiba (vs. HGST's Ultrastar Hs14) is their conventional magnetic recording technology, which ensures predictable writing performance and permits drop in compatibility of the HDDs with existing storage applications.
The author guesses it will have nine ~1.55 TB platters, like Toshiba's version. 9th-generation and beyond PMR platters that can store 1.8 TB or more may be seen before the technology is phased out:
[November 2017's] top-of-the-range enterprise-class 3.5" HDDs from Seagate and Western Digital can store up to 12 TB of data. They are based on eight 8th generation PMR platters featuring ~1.5 TB capacities. Toshiba is a little bit behind its rivals with their 10 TB units featuring seven 8th gen platters with 1.43 TB capacity. With the arrival of the 9th gen PMR platters in 2018, hard drive makers will be able to increase the capacities of their eight-platter models to 14 TB, while designs with seven platters can go up to 12 TB.

Just ban helium. Why would you ever need to own helium, citizen?
Or children, why would you ever need children?

Ownership of children does not require a license or a collar tag, unlike dogs.
Ownership of children is something that has been wanted for all of human history. Just get them vaccinated. And don't allow them to run in the streets in packs. Or become ferel.

Wanted != require/need, again, explain why do you need to children.

I can answer that.
There are pros and cons. And I know because mine moved out. No kids left in big empty house.
Pros of child: take out the trash!
I probably don't have to go into the cons.
Sometimes they make you proud. Other times, you stand behind them and support them anyway. Nothing like knowing your parents have your back and aren't ashamed of you even when they have to take responsibility for what you do and aren't happy about it.

Why would they bother filling a hard drive with helium? I don't understand?

The density is steadily advancing and yet the price per GB has been flat for many years now.

The issue is that the data density hasn't really changed at all for some time. PMR appears to have hit a limit at ~1.5T/platter. They're just stuffing more platters into the same drive enclosures -- probably by reducing the size of the mechanical components.
If you compare drives based on "price per platter" you will find that they're all basically the same which is why we have hit this plateau.
SMR actually increases density but comes with drawbacks that have limited its applications.

That's more than it used to be, and it seems that it can reach 1.8 TB, and possibly 2.0 TB. Beyond that we will probably see MAMR or HAMR.
