[quote]...Then, it is good that the 3-platter 7200rpm models all are faster than 100MBps. Seagate’s drives have always had very good sequential speeds and now notch 120MBps in the 3-platter design. And if you take a look at the graph, you can see that this speed is achieved not on one particular head/surface pair, but on all pairs. Hitachi’s 3-platter drives can be commended for good results, too. The 7K1000.B and E7K1000 have the best speed at the end of the partition. They also have good speed at the beginning and smooth graphs, thus showing very stable overall performance.
... However, the HDDs reach this speed on different data blocks. Being the best with small data blocks, the Hitachi 7K1000.B accelerates to 100MBps on 4KB data blocks. The Hitachi E7K1000 and WD RE3 reach that speed on 8KB data blocks. The Seagate and Caviar Black need at least 32KB data chunks for that. And Samsung’s models both reach the speed of 100MBps on 64KB data blocks. ... The Seagate SV35.3 differs for the better from the desktop model while the 3-platter WD Caviar Green with 32MB buffer is excellent on small data blocks.

Western Digital’s enterprise RE3 and desktop Caviar Black models feature the best read response time among all the drives. The result of lower than 12.5 milliseconds is very good for 7200rpm drives. Hitachi’s new models are just a third of a millisecond slower. They have improved by 0.5 milliseconds over their predecessor (but that’s not a record for this brand’s products because we have seen even better results from them). The 4-platter Seagate is also good with a response time of lower than 13 milliseconds.

IOMeter Western Digital’s drives deliver superb performance at the maximum load: 230 operations per second! By the way, it means that the drive performs two reads per each rotation of the platters. The Hitachi E7K1000, the best of the opponents, can only catch up with the leaders at pure writing.

Judging by the overall HDD scores of PCMark 2005, the Hitachi E7K1000 is the best 1-terabyte drive for a desktop PC. The WD RE3 and Hitachi 7K1000.B are better than the other 3-platter drives, too. And once again we want to single out the WD Caviar Green with 32MB buffer. Notwithstanding its lower spindle rotation speed, it is as fast as 3-platter 7200rpm drives.

The overall scores of this version of PCMark differ from those of the previous version. The Western Digital RE3 and Caviar Black take first and second places and enjoy a large lead over the Hitachi E7K1000 which is third.

...note the results of the new drives from Hitachi. Their new electronics is very power efficient, and their mechanics has become more economical, too. It’s time for the 5-platter ancestor to retire now.

First of all, we can name the fastest 1-terabyte drive in all our tests. It is the WD RE3 (WD1002FBYS). This is the best buy if you prefer maximum performance. But if you don’t like its high price, you can take the WD Caviar Black (WD1001FALS) which is somewhat slower but costs much less. The Hitachi Deskstar E7K1000 (HDE721010SLA330) is third in terms of sheer speed. The WD Green Power WD10EADS will be the best and only choice for a quiet and cold home multimedia center, though.[/quote]

warum gehört eine blaue hinein?
Ich seh zumindest bei geizhals keine WD Blue mit 1TB

Auch WD selbst listet die Blue nur bis 750GB.

joe: ja, das ist leider das problem, aber es ist doch auch so, dass die WD blue sicher viel öfter verkauft wird und zentraler am markt positioniert ist, als etwa die black. Und von der performance her ist sie auch 1A. Ich finds dennoch sehr fraglich, warum die blue noch kein update bekommen hat - hoffentlich kommt das bald. Wenigstens erklärt das, warum sie nicht dabei ist =).
