Nitty Gritty: Single-Drive per Volume RAID 0 vs. JBOD

I am looking at testing MapR for my employer and we want to see if MapR can handle some of our health care data warehousing needs.  I have some test servers that have drives hooked to RAID controllers.  Looking at the RAID cards, they don't support jbod, so I just figured I'd present each drive as a 1 drive RAID 0 volume.  Can the MapRFS, with all it's enhancements over HDFS understand the drive geometry properly when abstracted through a logical layer?  Will this setup even work?  If it does work, and I sacrificing some potential performance?  Are there any theoretical gotcha's if I then pushed this into a production environment? 

Also, please go into detail if you can.  Why this will work, why performance won't be a problem, reading through MapRs documentation, I see the big advantage is direct-to-disk but can't get my head around how a "logical" disk presented would do vs a real disk (i.e. if my servers had HBAs etc).
