Now, what's the difference?
WD Blue: RPM: 7200, Cache 64 MB, Capacity: 1TB
WD Black: RPM: 7200, Cache 64 MB, Capacity: 1TB

They say the Black one is slightly faster, but how? The specs are the same...

More about : black blue

Realistically the only difference is the color of the sticker, barely any more reliability in the black, and the black has a longer warranty.

The specs on the newegg page are confusing, title has 64MB for blue, but details has it as 16MB still...at the smaller capacities there's a difference (500GB, etc).

The Western Digital Black is faster and more reliable.
Unfortunately, it's louder and more expensive.

You didn't answer the question, at equal specs, how would it be faster?

Not all the specs are equal. It's the read and write speeds which make the noticeable difference. They're better on the black, but not by that much.

That's what I'm talking about, good stuff.

Here's a little breakdown: http://www.storagereview.com/western_digital_caviar_blu...

It is important to know that some of the older blues used more platters to make up the same capacity point. The blacks(or any drive) with higher density platters had been faster.

The specs being the same does not mean much because cache is only useful for a short time, once it gets down to actual performance of the platter/head combination things can change.

It is all additional specs. higher density platters are faster and faster rotational rates reduce latency(and a bit of drive firmware programming helps).

I know my WDC 1TB blue(the older model) was not near the black for performance(but it was still faster than the older 640gigabyte WDC blacks) as a boot drive(my old 1tb Seagate also took it to town in real world performance, but also never lasted nearly as long had many of this model fail).

For the OS, get the fastest you can(SSD if money would allow), but for storage, drive speed does not seem to have much of an effect on performance.

aren't the blacks dual processor?

And dual-stage actuators to adjust the height as well as the side to side position.
