First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.
Hitachi Deskstar 7K1000.D hard drive
This Hitachi hard drive has a single 1TB platter, lowering power usage and increasing speeds
Solid-state disks may be all the rage right now for their excellent speeds, low power consumption and small size, but plenty of companies have hedged their bets with tried, tested and traditional products. Good ol’ fashioned magnetic spinning-disk hard drives have been making technological leaps with every generation, and the Hitachi Deskstar is evidence of that: it boasts a single platter for its 1TB capacity, with denser storage with theoretical performance, reliability and power consumption benefits.
- Low power consumption
- Good read/write performance
- Low noise signature
- Slightly slow access time in testing
Hitachi's latest traditional platter-based hard drive is a good product: it cuts power over the previous model, runs quietly and without excessive heat, and has generally pleasing performance figures.

Hitachi Deskstar 7K1000.D: Design and features
To the untrained eye, the 7200RPM Hitachi Deskstar 7K1000.D looks identical to any other 3.5in form-factor hard disk drive. Closer inspection reveals that it’s slightly lighter than most other older drives, at 450g. Western Digital’s Caviar Black 1TB HDD is 690g, in comparison; the Deskstar’s single 1TB platter saves significant weight over the two-500GB-platter Caviar Black.
As we just mentioned, the dimensions of the Deskstar 7K1000.D are exactly in line with the 3.5in standard: the drive is 101.6mm wide, 147mm deep and 26.1mm tall. The requisite power and SATA connectors are on the drive’s end, and predictably this latest Hitachi is SATA 3 compliant for a theoretical 6Gb/s maximum throughput. After formatting, the Deskstar 7K1000.D’s 1TB capacity translates into 931.5GB of usable space.
Hitachi Deskstar 7K1000.D: Power and performance
Hitachi claims 3.7W power usage at idle, with 15 per cent lower idle power consumption compared to the previous 7K1000.C model. Another advantage of the single platter is generally low power consumption: we measured 4.4W during read/write versus the 6.7W our comparison Western Digital Caviar Black achieved. This might not sound like much, but if you’re running half a dozen of these drives in an impromptu file-server the difference would be noticeable.
The Hitachi Deskstar 7K1000.D 1TB model we tested was near-silent during operation, with only a small amount of noise audible during the disk's spin-up to 7200RPM: on par with the WD Caviar Black and significantly quieter than the Seagate Barracuda XT we used as benchmarks. The drive was also generally cool during operation, only getting warm rather than hot after an extended read/write torture session. These results, thankfully, are a far cry from other hard drives that bore the Deskstar name in the past.
Our test platform was an Intel Core i7-2600 CPU, 8GB of DDR3 RAM, a near-empty Intel X25-M 80GB SSD, and an AMD Radeon HD 6970 graphics card on an Intel reference design P67 motherboard, running Windows 7 Ultimate SP1 64-bit edition. We used the latest WHQL drivers, which were installed automatically when we booted up Windows with the Deskstar 7K1000.D connected.
Our real-world file write speeds were 146.1 MB/s for a single 8.3GB file, and 110.2 MB/s for a series of 1300 small files with a total size of 3.4GB. When we copied these files from one area of the drive to another, we measured an average speed of 60.5 MB/s. CrystalDiskMark returned a synthetic benchmark read result of 193.8 MB/s and a write result of 193.6 MB/s sequentially. These results are good and demonstrate the Hitachi Deskstar 7K1000.D’s good performance credentials. HD Tune Pro told us that the disk averaged an access time of 18.7 ms, with a burst rate of 205.2 MB/s — not great, but OK.
Hitachi Deskstar 7K1000.D: Conclusion
Hitachi’s latest and greatest hard drive is a generally good performer, with our only concern the slightly slow disk access time result. It’s quiet, cool and reasonably quick — if you can find one for a reasonable price post-Thailand flooding, we’d happily recommend it. We found the cheapest street price for it to be around the $129 mark.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.
The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.
My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
