Bottom Line

Judging by the performance results, it seems that the other manufacturers have caught up to Hitachi and now offer more competitive products at more competitive prices.

We have long been fans of Hitachi's Deskstar series of drives, because of their cool and quiet operation and also because of Hitachi's market-leading capacities. Indeed, Hitachi was the first vendor to introduce a 400GB desktop drive. Its current 400GB drive packs up to 62 gigabits of data per inch of space on its disk platters.

For this review we tested the 400GB HDS724040KLSA80 Deskstar model, in addition to the more mainstream 250GB HDS722525VLSA8. Both drives feature 8MB cache buffers, 7200rpm spin speeds and both have fluid dynamic bearings to reduce vibration and wear.

Our testing showed that the Hitachi drives are still devices to be reckoned with--albeit expensive ones.

In particular, the 250GB drive produced excellent performance results in our file transfer test, where it just outperformed a 250GB Western Digital Caviar. It was quite warm during testing, at 45 degrees, and it was noticeably audible during seek and read/write operations.

The 400GB drive was not as impressive in our tests, managing only 356MB per minute in our file transfer test. This is not at all competitive if you are looking for a very fast drive, and its working temperature was rather high at 44.7 degrees. Both drives have a three-year warranty.

STYLISTIC Q702

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

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.

STYLISTIC Q702

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.
