Hi i always had a concern relating to upgrading to Raptor or SSD i just really want to know by upgrading to these HDD will it def give a huge performance boost . We normally use this HDD for O.S Booting , making application run faster or gaming but does that really make a huge diff . I really want know what would be perormance Gap . OuR Current WDBLACK / .12 series are really fast so when u compare it with Raptor or SSD will the difference be noticiable.Kindly provide ur Views.
