Mac Pro - which drives will fit and not fit ?

Hi there,

I want to buy a 300gb raptor drive as my startup disk but I know some models don't fit the Mac PRO ( the connectors are not in the same place as the bay ).

I have a 2 x 2.8 octo core macpro.

Will this fit as a 10.000 rpm drive ? http://www.amazon.co.uk/Western-Digi...9950839&sr=1-7

Also I want to buy a couple of 1TB drives.

Any problems between http://www.amazon.co.uk/Seagate-Barr...9950894&sr=1-4 or this one http://www.amazon.co.uk/Western-Digi...9950941&sr=1-2

Any recommendations between Segate or WD Black caviar ? For the 1TB drives ?

Cheers in advance
