Interestingly, the 5D and Mini have a battery backup to safely shutdown the device and an mSATA add-on that purports to increase performance:

For my money, I much prefer Network Attached Storage, which admittedly moves at a slower 1Gbps. Drobo offers solutions in this area but I am currently using and loving my Synology Diskstation that resides in my closet instead of my desk. It has not been anything but reliable for months (expect a review soon).

If getting the fastest performance possible is your thing, you can also load up every drive bay with SSDs. Drobo gives you the flexibility to choose.

Drobo also announced a Drobo Mini Product that holds four 2.5-inch HDDs or SSDs.
