Indeed. There is room for improvement : should the 2 disks be RAID1 or 
parts of the same VG, as said ?

As it is recommended hardware, it would be interesting to know which 
kind of setup with 2 SATA disks is optimal ?

Of course, it does depend a lot of the usage : if you need to boot from 
volume, I would say having 2 physical PVs is better, but if you need to 
store critical data, then the RAID one is fine.
