Within the first week of having my MacBook, I had filled the hard drive. I had purchased the black model which gave me 80 GB of storage but with all the music files, photoshop documents, web site work, and different operating systems, I knew that I would fill that hard drive in no time. I kept that in mind when I purchased the computer and knew that new perpendicular recording laptop drives were on the horizon. I was waiting for the release date of the Seagate 2.5-inch 160GB laptop drive, but the Hitachi Travelstar 5K160 160GB drive had beat it to market and I was out of hard drive space so I went with that.
