Revolutionary 32TB Hard Drive Uses Lasers for Unparalleled Data Storage

Seagate has finally begun mass production of its largest-ever hard drive, a staggering 32TB in a single drive, thanks to heat-assisted magnetic recording (HAMR) technology. The company explains that increasing hard drive capacity involves fitting more data bits onto each disk platter, but this causes issues with thermal stability. To overcome this, Seagate developed HAMR, which uses lasers to momentarily heat a microscopic section of the disk to write new data. The company has been working on this technology for 17 years and last year announced that it had finally cracked it.
