WD Blacks have a more aggressive seeking style. It might be better actuator tech. I did see an article about that, way back.

No. It used to be quite close, back when F3's had more sequential speed - but the new Blacks are very fast at sequential stuff as well.

Yes.

Yes. That's definitely the new actuator tech.

Yeah. It's basically a dual-core controller. ("dual-proc") It can check more possibilities than a single core (and slower) controller can, so it can make smarter choices about which reads/writes to perform next, and it can think ahead more steps.

WD Blacks apparently also monitor vibration levels and mis-seek performance, then adjust accordingly, making them (and RE drives) better in server environments. I had heard that most Seagate consumer drives don't bother doing this, as it only has a big impact in multi-drive systems.

I have a Black and a seagate both 1 tb set up in a RAID1 array on my fileserver. same system, same data, same everything.

The first line is reading data from the drives cache memory and is quite similar as you'd expect. The second line is actual drive speed and you can see that the WD Black is 40 MB faster in 3 seconds.

That is a substantial difference and well worth the extra few dollars for the WD Black.

AAM stands for Automatic acoustic management . You can generally control the drive to either run quiet and slow or at full speed with the help of AAM.
It can be enabled in using HDtune if your HDD supports it.
