zMartin :
The best one I found is the Western Digital 1TB internal Hard Drive - Caviar Blue (3.5 inch) is there anything better for a similar price?
look for drives with :
1- 7200 RPM , 2- 64M Cache , 3- SATA 3 inteface , 4- 5 years warranty or Minimum 3 years if 5 is too expensive .
after this any drive you choose will be good , being Hitachi , Toshiba , Seagate , or WD
