Toshiba is sampling a 9-platter, 14 terabyte hard disk drive that uses "conventional magnetic recording", aka the traditional perpendicular magnetic recording (PMR) with no shingling:
The new series comes with both 14TB and 12TB disks that wield nine and eight platters, respectively. Toshiba also becomes the only company with a nine-platter drive with 18 heads. Each platter packs 1.56TB of data storage.
Competing HDD vendors (WD and Seagate) have used helium designs for several years, so Toshiba has largely been considered late to adopting a helium design. Toshiba fills the 3.5" drives with helium instead of air and uses a laser sealing process to contain the gas. The helium reduces internal air turbulence from the spinning disk. In turn, it reduces vibration and provides power, performance, and reliability advantages. It also allows the company to use thinner platters, which facilitates the additional ninth platter.
While Toshiba may be the last HDD vendor to market with a helium HDD, the company did it in style. The MG078ACA, which carries a tongue-twisting name because it is destined for the data center, currently weighs in as the densest HDD on the market using conventional recording techniques. That represents a 40% increase in density over Toshiba's previous-gen 10TB models.
[...] Toshiba currently has 24% of the HDD market share according to Coughlin and Associates, which comes in third to Seagate (36%) and Western Digital (40%). The company has been surprisingly resilient and has clawed back market share over the last year. The addition of a class-leading 14TB model should help it gain even more market share over the coming year.
Both drives have a 5 year warranty.
1.8 TB 9th-generation PMR platters are possible and could be used in a 16 TB Toshiba HDD late next year. Will we see 2 TB per platter without the use of HAMR/MAMR or shingles? Combine that with 12 platters (using a glass substrate), and suddenly you can have a 24 TB HDD.

I remember when the harddisks had swappable plates [auckland.ac.nz].

You know you are hardcore when you need a socket wrench to switch your hard disk platters :-)
Very cool, thanks for the share!

I actually tried to run programs on a machine using those (uni time)
Input from punch cards, compile errors (or any output) on listing. After 2-3 cycles of 'Here's the Fortran program on this stack of cards' - one week later 'Here's the compile-error listing, go repunch the typos', I gave up and started to use a ZX Spectrum clone.
(The above just in case you acquire the taste for retrocomputing)
