That should work.
Was thinking to place the 12-disks into one large RAID 5 (so that should leave me with 11 spindles) - I will place Data files and Index files here.
The existing array is another MD1200 with 12-disks as well, carved out into 2 separate drives, both RAID-10. So I will place LDF files on 1 RAID 10 and tempdb on another...
