Hi there folks! Long time reader, first time question-asker. I wanted to upgrade my internal hard drive on my 13" 2009 Macbook, but I had no idea which one to get. I understand that the requirements are 2.5" SATA, but beyond that, I'm not sure about product reliability. Wondering if any of you guys had recommendations on good internal HDs for the Macbook. I was thinking the Western Digital 320 GB Scorpio Black. Any further information or recommendations would be greatly appreciated. Thanks!
