Hitachi Travelstar 500GB 7200RPM Upgrade

After getting the new Macbook Pro 13in, I quickly used up the 250gb of space that was on it.  I then knew it was either I delete some files, or get a new hard drive.  I opted to get a larger faster drive as I really hate deleting files.  The install was a little more complicated then my previous Macbook…. Mainly just a few more screws to get the drive out.  After the drive was replaced I booted off the OS X CD.  I placed the old drive in an external case, towards the end of the install it allowed me to recover from another hard drive.  I pointed the install to the external drive and it took about 2hrs but it restored all of my files.
I ran xBench before and after to see if there was any improvement going from a 5400RPM drive to a 7200RPM drive. Here are the results.
