Rattling Raptor - are they meant to be this LOUD?

Rattling Raptor - Update with screenshots

Hi folks

I had a 150Gb Raptor X delivered from OCUK a couple of days back and as I'm typing I'm putting it to good use recoding and compressing a video from one area of the disk to another.

It doesn't seem all that quick at doing it...it's recoding at about 10,000Kb/s which isn't all that fast - I've had 12K-15K on my standard WD 320Gb SATA drives.

It's also very loud - really annoyingly loud, it's making the standard HDD stratchy noise, but just magnified...are they supposed to be this loud or is it just mine???

I've done some drive benchmarking today and it has come up with what I think is a weird result.

The drive speed is consistantly high - and quiet until it starts doing the ramdom access test when it gets really loud...when I get the results this is the graph:

Quick Benchmark


Long Benchmark

As you can see there is a significant dip in performance around the 100Gb mark....I've run a scandisk using the Windows utility with fix bad sectors option selected but it didn't report finding anything.

Any thoughts or advice would be welcomed at this point - do they do this or do I have a duff drive? I want to be sure before returning it.

Thanks
