Will this HDD fit my laptop?

Hi
I want to change my ASUS X55A hard drive. Will this one fit?
HITACHI TRAVELSTAR 7K1000 1TB 7200RPM SATA3 32MB 3HTS721010A9E630

There are a couple of laptop hard drive sizes, not in width/length but in height. Open up your system and see what height drive it has, and see what height the Hitachi is. Not all laptops won't work with different height drives, but some drive bays are designed to only fit one size.
