The 12 MB/s is likely due to the cache syncs and the default handling of those by the array.
As long as you create single drive vdisks, they can all be in the same pool. Just DO NOT create more than one volume using the same vdisk and then use zfs to stripe across those...unless you want guaranteed excessive head movement. If you get a warm fuzzy feeling by knowing precisely which drive is in use for each vdisk, either go check after you create it, or manually select which drive should be used when creating the volume... Just to be clear, the 128k stripe size setting is not the length a single stripe...It is the disk segment size... so the length of a single stripe is the number of data drives x the disk segment size.... I am not sure that zfs attempts to align IOs on any particular boundary, so you might want to try a smaller segment size to achieve a stripe length less than 128k if you are going to be doing lots of writes....
