Hi Hamish
This sounds like the exact problem I was having except my system would crash in Final Cut Pro when working with video files connected to the external enclosure. I don't have After Effects on this system, but I do also have the Black Magic Pro card installed.
I purchased this card:
http://www.cooldrives.com/4expcmaca.html
And initially installed the driver named: siliconimage3124r5_15160.tar found on this page:
http://www.siliconimage.com/support/supportsearchresults.aspx?pid=27&cid=3&...
It would crash my system as you were describing and would freeze on restart. I had to turn power off for several minutes then restart (couldn't just turn power off and right back on).
I was told from the people where I purchased my card and enclosure (cooldrives.com) that the 15160 is the latest RAID driver for that card, whereas the 203 is the latest non-RAID. It was suggested If all I planed to use the card for is the 5 bay enclosure, then the RAID driver is not necessary, and perhaps downloading the 151060 from SiI's site again may solve the problem.
So I downloaded and installed the non RAID driver: (Can't find the link right now, but it is the Sil3124_2.0.3_Sil_Pkg.pkg
So I downloaded and installed it since I'm not wanting to raid my drives and my system hasn't crashed since, but it sill wont restart, I have to shut it completely down for a few minutes then it will boot up.
So, I'm wondering if maybe part of the old driver is still loading. I'm thinking if I can completely uninstall the driver and reinstall the 2nd driver that I installed that it would fix my problem. Now that I read more on Silicon Images site (their FAQ section, I'm thinking I need to upgrade/flah the bios on the card, but the Silicon Image site only gives instructions how to flash the bios when installed in a PC, NOT a Mac, so I'm lost there.
This FAQ is one that also fit my problem:
"I installed the required Driver but the storage controller is not working?"
You can read the FAQ page at:

A girl that edits for me also bought this same card and installed the non RAId driver she doesn't have any problems at all, but she doesn't have the 5 drive bay enclosure that I have nor does she have a Black Magic card either, so I'm not sure if that part of the problem or not. I bet its a bios problem, if I could just figure out how to flash it on a Mac.
