Should I get this Western Digital Caviar Black WD5002AALX 500GB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive

or
HITACHI Deskstar 7K1000.C HDS721010CLA332 (0F10383) 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive

The WD is rated much higher, but the Hitachi has the storage... Will I really notice a speed difference between the two drives?
