The new Mac Pro although fast could be faster. Those using creative software such as Final Cut, Avid and Adobe often request faster hard drives. The Mac Pro offers little options as standard. main issue is the slow 3gb/sec sata connection linked with 7200rpm hard drives. HardSoft Flexible Leasing are now offering a 6Gb expansion card within the Mac Pro that will support two drives internally . This together with the very fast Western Digital Velociraptor drive which is 10000rpm AND 6Gig can really liven up the Mac Pro. Given the substantial cost of the Mac Pro this is quite a minor cost. Only downside is that the maximum drive size is 600GB but there no reason mixing additional 7200rpm/3gig drives into the four bays of the Pro.
