[Hard Drives] Laptop HDD's SOO Much smaller than desktop??

Hey Forum,

I have a question today regarding the image below. In this picture you should see two old hard drives I have. One is 320GB WD Scorpio Blue 2.5" Drive and the other is a Samsung Spinpoint 250GB 3.5" Drive. My question is, why is the Samsung Soo much bigger than the WD if it has a smaller capacity? It makes no sense to me. Another thing is that I am considering using these two drives in RAID 0 as storage for my new system. Would this work? As far as I know, it would be fine, but only 250GB of the WD would count towards raid, so the final result would be 500GB of storage.

    Different platter design and normally 2.5" (laptop) drives are more expensive to make. The 3.5" on the Samsung applies to the desktop standard so why make it smaller.

    The thing that puzzles me the most, is the weight of the Samsung vs the WD. The desktop HDD weighs almost 2 LBS, while the laptop one is merely a few ounces.
  3. LOL that would be obvious just based on the size! Another reason that laptop drives are more expensive!
