I think buy WD5002AALX. But i am not found information about platter size of these products. If new (WD5002AALX) one has a single platter, i will buy it. Old one is two platter , i know but why i didnt found any information about this specifications .
And some page ( http://support.wdc.com/product/kb.asp?groupid=613&lang=en)) say it (WD5002AALX)has 64mb cache another page ( http://www.wdc.com/en/products/products.aspx?id=100)) has 32 mb cache

Hello there,

I have received information from WD that the WD5002AALX model is a single platter design.
