3TB, 2TB & 1.5TB
3.5-INCH HARD DISK DRIVE
Enormous capacity – Up to 3TB of storage
Performance – extraordinary blend of capacity, performance and power efficiency
Ecological leadership – halogen-free design and power-efficient operation
Overview
The Deskstar™ 7K3000 is Hitachi’s first hard drive to deliver an enormous three terabytes of storage capacity and 7200 RPM performance in a standard 3.5-inch form factor. The 7K3000 is also the first Hitachi hard drive with a 6Gb/s SATA interface, which along with its 64MB cache buffer delivers a big boost to performance over the previous generation product. The Deskstar 7K3000 is designed to allow manufacturers to leverage the benefits of the latest components and operating systems to deliver high-performance, high-capacity, power-efficient systems. Manufacturers planning to use the highest capacity 3TB drive in systems should consult the Hitachi High Capacity Technology Brief. Deskstar 7K3000 is also available in 2TB and 1.5TB models that accommodate existing systems, as well as new designs.

Capacity - One GB is equal to one billion bytes and one TB equals 1,000GB (one trillion bytes) when referring to hard drive capacity. Accessible capacity will vary from the stated capacity due to formatting and partitioning of the hard drive, the computers operating system, and other factors.
Data Buffer - Portion of buffer capacity used for drive firmware
Availability - Intended for low duty cycle, non mission-critical applications in PC, gaming and external storage environments, which may vary from application to application. Note that customer environments may vary from application to application.
