Western Digital’s newly launched ePMR-powered UltraSMR HDDs can store up to 32TB, a new record for shingled magnetic recording-based drives.
Thanks to ePMR, which WD has used since 2020 to improve HDD capacity, and the storage company’s much newer UltraSMR technology, WD introduced an 11-disk design for the 32TB Ultrastar DC HC690. WD’s previous champion, the Ultrastar DC HC680, had 28TB of storage thanks to a 10-disk design and was the company’s first drive to use UltraSMR tech.
