I think XFS is the way to go if you need fast I/O.  Use large blocks.  
SGI invented XFS just for this purpose, performance.  Still 32MB/Sec
is about the most you can expect on a single drive setup.  

I've got a SATA drive in this iMac and I get about 32MB/Sec max.
Mac OS X is BSD UNIX based.  Hate to say it but you are on the
borderline.
