I'm about to pull the trigger on an HDD upgrade, and I'm actually a bit hesitant about making the wrong decision. I can't find a SATA drive at any of the stores around where we live, so the purchase will be made online. Just by past experience I'm leaning towards Seagate, but I've noticed that the WD 2.5" SATA drive at 160 GB has been on sale at around $80. (http://www.circuitcity.com/ssm/West...76764/catOid/-12973/rpem/ccd/productDetail.do) Another one I've seen is a 2.5" Seagate "Hybrid", but it claims it only works with Vista. Might be a little too new to try out. Anyway, I'm running an original, 1.83 GHz Macbook w/ 2 gigs of RAM, and I'll be upgrading to Leopard in a few weeks to run bootcamp for work. So, it's time for a new HDD, and I don't want to botch this decision. Any advice or warnings would be greatly appreciated. BTW, I'm thinking 120 GB-160 GB will be ample. No less than 120 GB, though.
