with raid 10 all four drives will appear as a single physical device
shared by all.  I'm personally not a big fan of logical partitioning
of a single raid device unless you are trying to keep a physical
volume under 1 TB for example.  Each sync on the volume is guaranteed
to sync all 4 disks regardless of how you set your partitions up.

escalade is a fairly full featured raid controller for the price.
consider it the ford taurus of raid controllers, it's functional and
practical but not sexy.  Their S line is not native sata but operates
over a pata->sata bridge.  Stay away from raid 5.
