Now we’ll try to sum all the results up.
The Hitachi Deskstar 7K1000 is just good. Like many other drives from this firm, it copes well with server loads, features superb deferred writing, processes small files quickly and can compete and beat its opponents in PCMark. But on the whole, the recording density of its platters is not high enough to be really competitive to the current generation of HDDs. The components should also be updated: the highest power consumption is not the result one could be proud of.
The Samsung F1 is very good. Yes, it failed the server tests as its firmware couldn’t cope with such load. But in most tests that resemble the typical load of home and office computers it was the winner or in the top three. This HDD also proved to have modest power consumption, so it is going to be rather cool. It is not without flaws, though. Besides its low server performance, it might do better in the multithreaded reading test. And its top speed should have been closer to that of the 1TB model of the same series.
Seagate’s HDDs should be discussed according to the specific generation. The generation of the Barracuda 7200.10 and Barracuda ES was the first to reach the capacity of 750GB but their performance is now disappointing. They took last places in most of our tests and may only be appealing now due to their low price.
The current generation, represented by the Barracuda 7200.11 and Barracuda ES.2, are the opposite of their predecessors. Their speed characteristics are outstanding. Seagate solved the problem of low speed of multithreaded reading and low performance in server tests. These HDDs were good in every test and were leaders in many of them, delivering terrific sequential read speeds. They are also among the best in terms of power consumption. So, these are two universal HDDs that are equally suitable for server applications and for desktop computers.
Western Digital’s Caviar Blue and RE2 turn to be average products that are neither record-breakers nor losers. As opposed to them, the Western Digital RE2-GP series deserves special attention because it includes two models behaving in a different manner. The WD7500ABYS delivers modest performance but features low power consumption (thanks to its spindle rotation speed of 5400rpm). The WD7501ABYS consumes little power too, but delivers higher performance. It is competitive to the other HDDs in the server tests, being even close to the leader in some of them. So, Western Digital did something miraculous to the firmware of this HDD. If your server needs a cold but rather fast HDD, this one should certainly be considered.
That’s all we’ve got to tell you today. We only want to add that this test session left a good overall impression because the developers not only increase the density of the platters but also work on the firmware. If they keep on doing like that, the upcoming generation of dual-platter 750GB drives is going to be tremendously fast!
