Toshiba opens curtains, reveals air-cushioned 5-terabyte terror

Take THAT, spinning rust flingers. HGST, Seagate - we're looking at you

MG04SCA 5TB drive

Toshiba, the newest third 3.5-inch disk drive manufacturer, has announced a 5TB drive, beating other suppliers except HGST.

HGST has gone 1TB better with its 6TB helium-filled Ultrastar product but Toshiba is the first manufacturer, we believe, to introduce a 5TB air-filled drive.

We're expecting 5TB drives from Seagate this year, but those will use shingled magnetic recording with overlapping tracks and poor rewrite speed.

The MG04 drives come in 6Gbit/s SAS and SATA versions and feature:

  • 2, 3, 4, and 5TB capacities
  • 5 platters - based on physical dimensions being unchanged from MG03 series
  • 1TB platters compared to previous 4TB MG03's 800GB platters
  • Sustained sequential streaming at 175MiB/s to 205MiB/s as capacity increases from 2TB to 5TB
  • Persistent write cache
  • Instant erase option
