You can never have enough storage and if you primarily use a notebook you more than likely know that storage space is a precious commodity. Most pre-configured notebooks that are available at brick and mortar stores come with 250GB or 320GB hard drives is seems. That may sound like a bunch of space when you are standing in the store, but after you put all your programs, games and digital media on the drive it usually doesn't leave you with much space for future growth. If you have reached or are nearing full capacity on your storage drive then you might want to consider upgrading to a larger 750GB or 1TB 2.5" notebook hard drive. If you are after performance then you'll want to stick to a 750GB drive as they are available at 7200 RPM and offer the fastest data transfers possible on a notebook hard drive. If you don't really care about performance and just want as much storage space as you can get in a 2.5" notebook drive then a 1TB 5200 RPM hard drive  is the ideal choice for you.
