To make your deployment faster, just use fdisk, disklabel, newfs to setup the disk and tar to copy the files.  That's a much smarter/faster way to go, even with TRIM support.  I automated it in 'growimg' for flashdist/flashrd, for instance.  Of course that assumes you only have one disklabel partition, but your servers are probably more complicated than that.
