My System Specs

Wink Home Benchmarks: 74GB Raptor vs 150GB Raptor

Hey guys, I was operating a 74GB Western Digital Raptor 10000rpm SATA 16MB Cache hard drive as my system HD for a while now.

But I got ahold of the 150GB version now because the 74GB was too small. Believe it or not there is SIGNIFICANT difference in performance between the two.

On paper, they have the same seek times, etc, however in real-world usage the 150GB is a superior drive. Here are some home benchmarks I performed:

As you can see, the 150GB Raptor is MUCH faster in certain applications. I think this is due to its two internal platters as opposed to one on the 74GB. However, the seeking noise is certainly louder on the 150GB model. Even when copying a file FROM the Raptors to a WD5000AAKS, the 150GB sustains a rate despite the destination being slower.

Finally, here are some HD Tune 2.55 graphs. Here, the HDs appears identical.

Don't mind the temperatures. At the time of testing, the 150GB Raptor was sitting flat on the floor outside of the case (thus it's hot) while the 74GB Raptor was inside the case with a fan blowing on it. Under normal conditions, the 74GB Raptor is around 27-28 degrees Celsius and the 150GB is around 30-32.
