When I installed this diver, all of a sudden my CPU started running at 25%+ with no programs open, and when I disabled it, the CPU went back down to 1-2% idling. Is this driver needed/is this a known bug with this driver? I didn't find anything online.

I won't be doing any RAID systems (at least for now), so if this is the only thing this driver does I'll just keep it uninstalled.

You don't need this driver unless you intend to set up software RAID (fakeraid) using your motherboard's Intel chipset.

If you convert to fakeraid later, install the driver on your existing system just prior to installing the new drives, so that it will be more likely to boot afterward.

Okay great. Any thoughts/suggestions as to why it's using 25% of my CPU? It's an i5-3450 (ivy bridge) –  nathpilland Jul 23 '12 at 21:38
