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.

    The first number is the truth, the second is the lie. But, really, they're both "lies" in that the filesystem takes up some of the space.

    This whole "controversy" is why units like mebibyte and gibibyte were invented. The base 10 numbering is the correct one, as that's what those prefixes mean. The use of Giga and Mega to mean something other than billion and million respectively was never the correct terminology. You can sort of get away with that in the US where we don't generally use SI prefixes, but in the rest of the world, it was blatantly wrong.
