18 TB HDDs: Toshiba Collaborates with Showa Denko for MAMR HDDs
Showa Denko K.K. (SDK) announced on Thursday that it had completed the development of its microwave assisted magnetic recording (MAMR) platters for next-gen hard drives. The company is set to ship platters to Toshiba, which plans to start sampling of its new 18 TB nearline HDDs later this year. In addition to MAMR media, Showa also plans to release disks based on the heat assisted magnetic recording (HAMR) technology in the future.
The new 3.5-inch platters from SDK feature a 2 TB capacity and a new magnetic recording layer whose coercivity can be lowered using microwaves (see our brief description of the MAMR technology). SDK is not specifying which magnetic alloy or substrate it's using for its 2 TB media, but according to Western Digital, both should be very similar to those used for today's platters based on the perpendicular magnetic recording (PMR) technology. Which for Toshiba and its consumers means predictable pricing and reliability.
SDK says that Toshiba is set to use nine 2 TB platters for its 18 TB MAMR-based nearline HDDs, which will begin sampling later this year (and which will probably be commercially available in 2020).

Did you pick up a 5 TB drive and are now waiting for 20 TB? Yes, it is very close. But you might not like the initial prices and should factor in an extra year or so for consumer-oriented versions to appear.
1:0. Something I just recommended to somebody else.
Spinning rust should be in an external enclosure or NAS. A $100 1 TB SSD should be sufficient for holding most of your applications and small data. Maybe 2 TB if you are installing lots of 50 GB games. Videos and other large files should be on the spinning rust. Use off-site backups if you need them.
