WD Caviar Black 2TB

Zitat

After all, its predecessor, the Caviar Black 1TB, has reigned as the fastest all-around 7,200-RPM hard drive for quite some time now. The terabyte model's platters have only 334GB each, so the new Black represents a substantial 50% jump in per-platter capacity.

The Caviar Black comes out on top in two of three load time tests...

With the Caviar Black 2TB dominating the file creation and read tests, it's no surprise that the WD drive offers the quickest file copy performance, as well.

The Caviar Blacks thoroughly outclass their rivals in IOMeter, and the latest 2TB flavor offers a healthy performance boost over the old terabyte model. Three of our four IOMeter test patterns include a mix of read and write operations, but the web server pattern is made up exclusively of reads. The Blacks don't have quite as big of a lead with the web server pattern, especially at heavier load levels, suggesting that strong random-write performance deserves much of the credit for their domination here.

The terabyte Caviar Black has always been a little on the loud side, and this new 2TB model is no different. Generally speaking, the more platters a drive has, the louder it is, making the four-platter 2TB drive's higher noise levels no surprise.

If you need to buy a high-performance 2TB drive today, the Caviar Black is obviously the one to get. It's your only option, after all.
