Hello -

Out of warranty PS6100 w/ 22 1 TB drives, plus 2 1 TB hot spares -  RAID 10. We are considering upgrading to 2TB or 4 TB drives. Is there a way to upgrade these drives easily without losing any data, etc?

If we do bump up the drives we'll be purchasing an additional 2 years of support. We're weighing upgrade and replacement options right now.

Thanks!
