I have one of these
http://www.amazon.com/Compact-Flash-Cards-Adapter-Enables/dp/B0024MLGKU
its a pci card that will take compact flash cards and raid them.
what i am looking to do is use that as my boot device to ensure that i have a redundant system drive.
I do plan on upgradig to plus or pro so i understand i will need to keep a usb key plugged in to bind my key to. has anyone tried using a bootable flash type of device like this?
