Simon raised some sensible points. Also consider a raid5 of the 4x500 drives and using LVM to join them to= a raid 5=20 of the 6x250s The benefit using raid0 to join the 250s may be that you can replace ea= ch of the=20 2x250 with 1x500 as time passes. In that case you may want a raid6 made= of : 500 500 500 500 250+250 250+250 250+250 One thing I'd ceertainly suggest is creating partitions of 498Gb to all= ow for=20 geometry variations....
