I am after a new SATA II fast and reliable 500 GB HD.
Quite undecided which one to go for in between this 3 models as follows :

Samsung SpinPoint T HD501LJ 500GB SATA-II 16MB Cache
Seagate Barracuda 7200.10 500GB ST3500630AS SATA-II 16MB Cache
Western Digital Caviar SE16 500GB 5000AAKS SATA-II 16MB Cache

Which is the faster of this three ?
and which one would you raccomend ?
