How to upgrade RAID 5 array
I have a Dell T410 server with a Raid controller and 4 x 146Gb HDD in a RAID 5 array. This only gives me 438Gb usable space.
I have two spare slots in the server. Which option would be best?
1) Add another couple of discs and have a RAID 5 array of 6 discs?
2) Add a disc outside the RAID configuration
3) Upgrade all 4 discs to larger capacity, say 4 x 1TB
4) Any other option I've not considered
This is a live machine so downtime is limited and I'd like to keep the risks as low as possible. It's near its end of life (SBS2008) so I just need to keep it running for a bit longer

I like the idea of adding a RAID1 array and then testing the bare metal restore at the same time. A good low-risk plan.
I've contacted Dell Tech support and requested a quote for 2 x 1TB SAS drives which I shall order and install.
