Jean,

  If you have 6 disks in a 620 then you have disk can space for 10 
drives. You can add drives to the exiting RAID set. So for the price of 
4G drives today I'd just purchase 4 of those boys used and stuff them in 
there. Add them to RAID then add them to the ASP and shazaam you get 16 
GB more space. Hands down the cheapest fastest and least exposure.
