Toshiba said earlier today that it now offers new 6 TB disk drives. The MG-04, with capacities of 2, 4, 5 and 6 TB, spins at 7200 RPMs, making it a nearline drive.

Toshiba claims it is good for 24/7 usage such as in servers. It has 12 Gbit/s SAS or 6 GBit/s SATA interfaces and a secure instant erase option to prevent encrypted data falling into the wrong hands.

This is a 2nd generation MG-04 drive. The prior one topped out at 5 TB and used 6 Gbit/s SAS and SATA interfaces.

As one would expect the range supports both industry-standard 4K native and 512e Advanced Format sector technologies.

Toshiba added that the new drives feature persistent write cache technology which protects them against data loss when power fails suddenly.

Compared with the 4 TB MG-03 generation drives, the uprated MG-04 6TB jobs feature:

  • 12 Gbit/s SAS and 6 Gbit/s SATA interfaces
  • A 30 percent increase in maximum sustained data rate
  • A 50 percent better power efficiency
  • The new drives weigh 720 grams at 2 TB and 770 grams at all other capacities. Toshiba doesn't reveal the number of platters or the areal density of this second generation MG-04 product.

    Seagate has an 8 TB drive and HGST goes up to 10 TB with its helium-filled Ultrastar drive. Can Toshiba keep up? We'll keep you posted with up-to-the minute news.
