Is it true that for SAS hd to work with a PERC 5 controller it must have a special firmware on it put in by Dell which forces you to buy a hd only from them. The hd that came with the server is a Seagate Cheetah 15K.5, but I don't know if its being 'value added' firmware by Dell.
Price of a 146GB Seagate SAS 15K is $180 from newegg, while Dell charges $420 For 300Gb $270 from newegg and $620 Dell
