When LSI says that the 9211 has a fixed 64K "stripe" size, they must really mean strip size, not stripe size, right?

If so, it seems like that might be part of the reason why random IOPS are good, while I/O for "medium-sized" files isn't as good as the 9260 -- since random I/O would tend to use all drives at once (given a large enough QD), while file I/O would tend to focus I/O more heavily on a smaller number of drives (64K strip x 8 drives = 512K stripe).

I wonder how the performance of the 9211 compares to a 64K strip size on the 9260 (with and without caching enabled)?
