Hitachi Global Storage Technologies (Hitachi GST) today introduced
its new enterprise-class, 3.5-inch, 3TB Ultrastar 7K3000 drive family
- the first 7,200 RPM drive family rated at 2.0 million hours MTBF
and backed by a five-year limited warranty.
The new Ultrastar 7K3000 drive family represents the fifth-generation
of Hitachi's five-platter mechanical design. With millions of
five-platter Ultrastar drives shipped over the last three years,
Hitachi's field reliability data shows an unprecedented AFR below
0.40 percent, exceeding industry AFR quality specifications for a
7,200 RPM drive. By increasing the MTBF to 2.0 million hours, with an
AFR 40 percent lower than drives rated 1.2 million hours MTBF,
Hitachi enables data center managers to expect reduced failures,
improved up-time and lowered TCO when using a large population of
Ultrastar 7K3000 hard drives over a period of time.
Providing the best watts per gigabyte (watt/GB), the Ultrastar 7K3000
drive delivers 50 percent more capacity in the same footprint and
does so at a 32 percent reduction in watts/GB versus Hitachi's prior
generation Ultrastar A7K2000 drives. With its dense 3TB capacity, it
is now possible to achieve an 1.8PB in the footprint of a standard
19-inch enterprise storage rack by stacking 10 4U, 60-bay enclosures.
Hitachi's 3.5-inch Ultrastar 7K3000 capacity density also allows
better utilization of floor space in terms of GB per square foot
(GB/sq ft.) and watts/GB when compared to 2.5-inch,
capacity-optimized, 7,200 RPM enterprise hard drives. Today these
2.5-inch drives cost roughly twice the dollars per GB ($/GB) of 3TB,
3.5-inch 7,200 RPM drives with 66 percent less capacity. To reach the
same capacity as a 3TB, 3.5-inch Ultrastar 7K3000 drive, enterprises
would have to purchase three 1TB 2.5-inch 7,200 RPM drives, which
will consume up to 170 percent higher watts to power the drives and
will occupy three times the storage array slots.
The Ultrastar 7K3000 family represents the first Hitachi 7,200 RPM
drives that are available in both 6Gb/s SATA and 6Gb/s SAS interfaces
for easy integration into legacy and new storage environments. All
Ultrastar 7K3000 drives are designed, built and tested using
Hitachi?s 10K RPM technology and quality standards.
The Ultrastar 7K3000 SATA and SAS models are available with a bulk
data encryption (BDE) options. While the Ultrastar 7K3000 SATA model
uses proprietary Hitachi encryption, the Ultrastar 7K3000 dual-port
SAS model is targeted at emerging 6Gb/s SAS enterprise
infrastructures and is designed to meet the industry standard TCG
Enterprise_A encryption specification.
The new Hitachi Ultrastar 7K3000 family comes in 3TB and 2TB
offerings, and is now shipping with a 6Gb/s SATA interface worldwide.
The Ultrastar 7K3000 6Gb/s SAS family will be available in mid-2011.
