I do a lot of video encoding so I need raw horsepower. I often have multiple apps trying to write to drives at the same time so I need a lot of throughput.
You're not going to get "a lot" of throughput on any MacPro, since they have only have SATA rev. 2 ports on the drive connectors, which is a max of 300MB/s.
However, having said that, 300MB/s is still fast. You can get top speed if you use SSD drives with everything you do, but that's getting crazy expensive.

On the other hand, with a Mac Pro there is the option to add Fibre Channel or other high speed data connections. Older models had the RAID card option which supported use of SAS drives instead of SATA. Some of this can be done with an iMac over a Thunderbolt connection now, and since the prices on that option are getting a little less, that may be an option for some.
