Hitachi Deskstar 1TB HDS721010KLA


We find it hard not to gawp, slack jawed, at this miraculous Hitachi drive. For anyone who remembers the heady days when 20MB hard drives were the norm, it's sometimes hard to comprehend how 1,000,000MB can now be squeezed into the same space

Huge storage, Great performance

Both storage and performance make this one of the leading drives on the market

Hitachi Travelstar Z7k320 review


It's often difficult to find replacement hard disks for an ultra-portable laptop or netbook, as most 2.5in disks are still too large to fit inside such compact systems. Anyone looking to upgrade should consider the slim Hitachi Travelstar Z7K320, as...

Not the largest capacity, but solid performance makes this an ideal upgrade disk for an aging laptop disk that's filled to capacity.

Hitachi Deskstar 7K1000.C 1TB review


The Hitachi Deskstar 7K1000.C is one of the cheapest 1TB internal hard disks we've seen. It costs just 5p per gigabyte thanks to its low price of just £45. Previous Deskstars we've seen have done quite well in our file transfer benchmarks and we had no...

The Deskstar may be cheap, but its inconsistent performance and short warranty means it's poor value.

Hitachi TravelStar 7K500 500GB review


The Hitachi TravelStar 7K500 500GB hard disk drive has a 2.5-inch form factor.

The usual argument against 7200rpm drives for laptops was built around increased vibration, heat and power consumption as compared to normal drives. The Hitachi TravelStar 7K500 500GB drive manages to strengthen its case by providing improved speed yet...

Hitachi Deskstar 7K1000.B-750 review


Hitachi's 750GB 7K1000.B-750 has one of the lowest costs per gigabyte in this test, beaten only by a fraction of a penny by Seagate's 1.5TB Barracuda.

Hitachi Travelstar 7K320 notebook drive review


Hitachi's new 320GB 7200rpm notebook drive promises a step-up in performance for your laptop

Exchanging the original 5400rpm hard disk with the Hitachi 7200rpm drive introduced a clear and measurable increase in system performance. The trade-off is a slight increase in disk noise and vibration, but this should only be apparent in quiet...

Hitachi Ultrastar A7K1000 HUA721010KLA330 review


Unlike the other Hitachi disks here, the Ultrastar comes with a five-year warranty.

Hitachi Deskstar 7K1000 1TB hard drive


The Hitachi Deskstar 7K1000 is the UK's first single 1TB (terabyte) hard drive. And our review of the Hitachi Deskstar 7K1000 shows it can hold 150 high-definition movies or more than 300,000 high-resolution photos.

Vast capacity and superb performance more than make up for the expense. Hitachi is the first to the 1TB hard drive market with the Hitachi Deskstar 7K1000, and this is one case where first may mean best.

Yet another green iteration of the Hitachi terabyte hard drive


Product Specifications

The Hitachi Travelstar 5K80 series is a 9.5mm high, 5400 RPM, 2.5-inch mobile hard disk drive ideal for today's data-intensive business needs. The Travelstar 5K80 brings a new generation of 5400 RPM mobile solutions to the long legacy of the Travelstar family of hard disk drives. This next generation of mobile hard disk drives provides a design which combines years of research and development with award-winning technology including: Antiferomagnetically-coupled (AFC) technology "pixie dust", Giant Magnetoresistive (GMR) heads, Fluid Dynamic Bearing (FDB) motor technology, Partial Response Maximum Likelihood (PRML) digital channel, head load/unload technology, Enhanced Adaptive Battery Life Extender (ABLE) 3.0, and an ATA/100 interface. With this design, the Travelstar 5K80 provides the storage capacity, performance, power management, quality and acoustics required by demanding computing/application requirements. The Travelstar 5K80 reaches areal densities of up to 70Gbits/ per square inch written on each disk. This feat was achieved by adding another layer of "Pixie Dust"- or in more technical terms, another ruthenium/magnetic layer to create a five-layer sandwich called laminated "Pixie Dust". These additional layers bring even higher thermal stability to the media, allowing data recording at ultra-high densities while maintaining data-integrity. Designed to meet the demanding needs of today's data-intensive requirements, the Travelstar 5K80 leverages proven technologies such as True Track Servo, which eases system integration, enhances hard disk drive reliability, and adds robustness against vibration and disk shift, Drive Fitness Test (DFT), and S.M.A.R.T. (Self-Monitoring Analysis and Reporting) technology which is designed to enable a hard drive to predict impending catastrophic failure. As a result of the award-winning combination of technology designed into the Hitachi Travelstar 5K80 series of hard disk drives, they are suitable for demanding, high-capacity Internet, digital audio and video editing, video streaming, and real-time multimedia applications - whether users are in the office or on the road.
