Differences between WD 1600JS and 1600AAJS?

Hi.

I'm unsure about the differences between these two drives. The Western Digital WD1600JS Caviar SE 160GB 7200RPM SATAII/300 8MB Cache and the Western Digital WD1600AAJS 160GB Hard Drive SATAII 7200rpm 8MB Cache.

Someone recommended me the AAJS and stupidly bought the JS by accident. I was told the AAJS is a single platter design and is quite a bit faster. I read on another forum that 'As far as I can tell JS is manufactured before December 2005, AAJS is manufactured in December 2005 and after', but my drive was manufacted june 2007 and its called the WD1600JS. Would it still be a 2 platter design even now?

I've seen the AAJS on the site I bought the harddrive on and I'm thinking of sending the JS back and getting the AAJS.

What do you think?

The WD website is about as much use as a kick in the crotch when it comes to things like this. It shows the 1600JS and 1600AAJS as having the same spec etc but then has subtle differences for 2 and 3 platter designs

The general consensus elsewhere is that the AA designates the use of the 166Gb platter so in the case of the AAJS only a single platter.

The only real way to be sure (short of opening it up) is to benchmark it. A single platter drive should give results similar to a 320Gb or 500Gb AAKS.

One less platter.
