some confusion here, perhaps.  I've noticed that many hardware raid 
controllers use "raid1" to refer to both raid-1 (2 disks mirrored)  and 
raid-10 (2*N disks mirrored and striped).

with 4 disks in a single raid, you would actually have a raid-10, which 
is two mirror sets striped together).   after building the raid in the 
disk controller (or if its not a hardware controller, building a 
software raid with mdadm), you would create a new file system on it with 
mkfs, then mount it as a directory (adding it to /etc/fstab for 
permanent use) so you could start putting files on it.    I often mount 
my 'aux' file systems as /u10, /u11, ...
