I have a raid-5 array of six 250gb hard drives.
I just bought four 500gb hard drives.

Simon raised some sensible points.

Also consider a raid5 of the 4x500 drives and using LVM to join them to a raid 5 
of the 6x250s

The benefit using raid0 to join the 250s may be that you can replace each of the 
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 allow for 
geometry variations....
