Seagate Ships First Industrial HAMR Laborious Drives

Seagate introduced this week that it had begun the primary business income shipments of its next-generation HAMR arduous drives, that are being shipped out as a part of Seagate’s newest Corvault storage methods. This commercialization marks an vital milestone within the HDDs market, as heat-assisted magnetic recording (HAMR) is anticipated to allow arduous drives with capacities of fifty TB and past. In the meantime, HDDs using perpendicular magnetic recording (PMR) and shingled magnetic recording (SMR) applied sciences are anticipated to stay in the marketplace for the foreseeable future.

We shipped our first HAMR-based Corvault system for income as deliberate throughout the June quarter,” said Gianluca Romano, chief monetary officer of Seagate, on the firm’s earnings name. “We anticipate broader availability of those CORVAULT methods by the tip of calendar 2023.

In the meantime, the corporate kept away from releasing particular capability particulars of the HAMR arduous drives utilized in these income Corvault methods.

Past Corvault methods, Seagate additionally shipped its HAMR-based arduous drives to key prospects amongst hyper scalers for testing and analysis. Hyperscalers, as a consequence of their in depth storage necessities, are anticipated to learn considerably from capability factors exceeding 30 TB. Although with the brand new know-how at hand, in addition to barely greater energy necessities for HAMR drives than commonplace PMR and SMR arduous drives, the hyperscalers are additionally enjoying it protected and completely validating the drives to make sure constant efficiency.

Seagate’s preliminary 32 TB HAMR arduous drives will use the corporate’s 10-platter platform, a system already confirmed and presently in use.

Growth efforts on what could also be our final PMR product are nearing completion and can lengthen drive capacities into the mid-to-upper 20TB vary,” Mosley stated.
