Hitachi Deskstar 7K2000: HDS722020ALA330, 2TB

 

Hitachi did not take part in the first wave of 2-terabyte HDDs (those with a spindle rotation speed of 5400rpm and 5900rpm), but not to release 7200rpm products would hurt the company’s prestige too much. Therefore, the new Deskstar 7K2000 series was introduced. The word series is somewhat too loud here as it includes but one model as yet. On the other hand, the other makers do not introduce 1.5TB 7200rpm drives, either.

The design of this series is unique if compared to the opponents’ products, but traditional for Hitachi’s high-capacity HDDs. We’ve got five platters and ten heads here, again. And the question is if Hitachi used platters with a recording density lower than 500GB or just reduced the operating zone of each platter.

As usual, there is also a server-oriented Deskstar A7K2000 series which features a much lower rate of irrecoverable errors.

Seagate Barracuda LP: ST32000542AS, 2TB

 

This model is already familiar to us from a previous review. It is the first drive from Seagate to achieve a capacity of 2 terabytes. And it is also the senior representative of the new Barracuda LP series which has a spindle rotation speed of 5900rpm. We include it in this review for the sake of comparison as a representative of the first generation of 2TB products.
