Western Digital has announced a 12 terabyte helium-filled hard disk drive, as well as an upcoming 14 TB shingled magnetic recording HDD. The 3.5" 12 TB drive contains a whopping eight 1.5 TB platters, and does not use shingling:

HGST's Ultrastar He12 HDDs use speedy PMR (Perpendicular Magnetic Recording) technology in tandem with eight platters to provide a beefy 12TB of capacity. The 7,200-RPM HDD provides solid performance measurements of 243 MiB/s of sustained sequential performance and 390/186 read/write IOPS at QD32. The helium-infused HelioSeal design allows the drive to scale to eight platters and provides a 2.5 million hour MTBF. [...] The hits don't stop at 12TB; the company also has a 14TB SMR (Shingled Magnetic Recording) HDD on its immediate roadmap.

WD also announced an Ultrastar 8TB SN200 SSD, and confirmed that it is working on QLC NAND SSDs that store four bits per cell. Micron also announced an 8 TB (7680 GB) SSD this week.

    Read the article about the SSD, it is a TLC drive with user adjustable over-provisioning. So, you get to choose if you want the full capacity of the drive (with lower write endurance) or set a lower capacity (and get higher lifetime from the drive.)

    The new FlexCap feature allows users to manually adjust the overprovisioning, which allows users to adjust an Eco to the Pro or Max level, and likewise the Pro model can shift into the same performance and endurance of the Max.

    So their three models (ECO/PRO/MAX) are the same drive with different settings.

    Micron based all three of the models upon the same underlying Marvell Dean controllers and 3D TLC NAND, but Micron varied the performance and endurance through overprovisioning adjustments. The single architecture allows OEMs and hyperscale customers to qualify one drive design that meets all three of the primary use cases.
