Western Digital presented a 10 TB hard drive in the Ultrastar DC HC300 family

Although in recent years the increase in hard disk space is mainly due to the use of helium filling technology, the development of air-filled drives also continues. The confirmation is the Ultrastar DC HC330 model with a volume of 10 TB, presented this week by Western Digital.

Western Digital presented a 10 TB hard drive  

The manufacturer notes that the new member of the Ultrastar DC HC330 family is based on a proven platform, thereby providing a simple and secure way to increase storage by migrating from smaller HC300 drives. It is interesting that in the new accumulator there are fewer plates and heads in comparison with the accumulator of the same volume, in which the filling of the hermozone with helium is used.


Compared to the Ultrastar DC HC510 helium hard disk with a capacity of 10 TB, the Ultrastar DC HC330 drive provides performance gains of up to 40% with a shallow queue depth and recording of small random access blocks. This performance boost is provided by the Media Cache Plus feature, which was previously only available on Ultrastar DC HC510 models with a SAS interface. It is built on the use of caching in non-volatile cache (NVC).


The advantages of the Ultrastar DC HC330 include a backup of the firmware to prevent accidental data loss in the event of a power failure during the firmware update. In addition, the use of firmware, signed by RSA, prevents hacking with unauthorized firmware. To protect data from unauthorized use, Ultrastar DC HC330 has hardware encryption.


Deliveries of 10 TB HD Ultrastar DC HC330 should begin in September.
