Hitachi introduces 7200 RPM 2TB hard drives

Can be integrated into new and existing storage systems

By CBR Staff Writer

Hitachi Global Storage Technologies has introduced new 7200 RPM 2TB hard drive, the Ultrastar A7K2000. The company claimed that the new offering is designed to ensure enterprise-class mean-time-between-failure (MTBF) of 1.2 million hours in demanding 24×7 nearline applications.

The Ultrastar A7K2000 drive is an enterprise SATA drive for applications such as data warehousing, disk-to-disk backup, cloud computing and scale-out storage implementations where storage density, GB-per-watt and cost-per-GB are the parameters, the company said.

In its fourth generation, the new drive can reportedly be integrated into new and existing storage systems, enabling higher capacity density and drawing less power in the same 3.5-inch footprint.

The SATA drives are said to feature the company’s Rotational Vibration Safeguard (RVS) sensor technology, which optimises drive performance in multi-drive RAID arrays and rack-mounted systems.

With five power management modes, a 36% reduction in watts during low RPM idle mode, and using less than 1 watt during standby/sleep modes, the new offering can help data centres achieve lower AC power and HVAC requirements, the company said.

The new offering is also available with a bulk data encryption (BDE) option. When enabled, the Hitachi BDE implementation encrypts all data on the drive using a private security key as it is written to the disk, and then decrypts it with the key as it is retrieved.

Brendan Collins, vice president of marketing at Hitachi GST, said: “With the addition of the A7K2000, Hitachi GST continues to provide one of the broadest ranges of enterprise storage products in the world – from premium, enterprise-class, capacity-optimized SATA drives to performance oriented 10,000 and 15,000 RPM drives – ideal for virtually every aspect of storage in the data centre.”
