They had "disk striping" which let you spread files or a database across several drives for faster access and/or redundancy. Not really that new since a disk with multiple independent heads is essentially the same problem & I think those were in existence a long time ago. Its a useful technique. I'd consider that to be outside of the "file system" as an "implementation detail" peculiar to a specific kind of device. A RAID or JABOD would be just one storage medium among many. (Should a file system support paper tape, punch cards and similar devices?)
