Which means that it was not a mistake on Intel's part leaving the Hardware ID's out of the RAID .inf on the previous version. There's certainly a reason for it. Mistakes don't happen twice;)
It's not probably "left out". If they don't add it, it means there is a potential problem. And we're talking storage here so you guys should be helpful that it doesn't get added. It's not a video card that fails and it fails. If storage fails your files go with it.
if your video card fails, you can't see what you are doing. you can always add in a card for storage just like video, and i would assume enterprise do just that, and not rely on onboard storage...i think it's not worth their (intel) time to do so. we bought in to this platform. it's 'old' now. everyone buy the newest one...

Well if a video card fails, it's true you can't see anything but you lose nothing (and we're talking drivers here not hardware fail). You get into safe mode remove driver and you're back in game. If storage fails you can lose valuable things. Those photos of your family vacations, or the presentation you prepared yesterday for work, etc etc etc. Data you can not replace. You seriously don't won't the driver enabled if it has any serious issue and the fact that C600 is not enabled on both versions hint that something doesn't work right.
I use the 3.5 but I'm not actually using the Intel SATA...I only have a DVD-RW drive connected to it:p My drives are connected to the controller in my sig (which doesn't do fail and doesn't lose data even in case of power failure;)). My data are far too important to me so I'm using 2x RAID 5 arrays + weekly incremental backups of any work related stuff (in case I get extremely unlucky and 2 drives fail at the same time--that's how much I value my data:)).
