Western Digital HDD capacity hits 28TB as Seagate looks to 30TB and beyond https://arstechnica.com/gadgets/2023/08/western-digital-hdd-capacity-hits-28tb-as-seagate-looks-to-30tb-and-beyond/ "After a couple of decades of talk, Seagate announced earlier this year that it was shipping samples of huge 32TB hard drives using heat-assisted magnetic recording (HAMR). The new kind of drive technology uses lasers to heat disk platters during writing, making it possible to store more data on a disk without increasing its physical size. But there's still a bit more capacity to be wrung out of older and more-proven recording technologies like perpendicular (or conventional) magnetic recording (PMR/CMR, often used interchangeably) and shingled magnetic recording (SMR); Western Digital announced this week that it's preparing to sample huge 28TB hard drives based on those technologies"
