*SM will devote a thread to each volume, making for gains in parallelization.
I'd be cautious about achieving that with partitioning as you're dealing with
a single read/write head, which can result in thrashing if there is substantial
activity for the volumes on that drive.  With discrete disks (vs. an ESS), I'd
personally go for 4 GB units and add them without partitioning, as they're
high-performance, and relatively cheap in these days of much higher capacity
drives.  With moderate activity on the storage pool you can certainly see
improved performance with partitioning.  The fun of Configuring.
