SSDs - RAID or Mirror ?

Hi all

I have a customer who has a ordered a system with 4 x 387Gb SSDs in the CEC
and 24 x 283Gb disks housed in a 5887.

With respect to the SSDs, what is the better approach - Mirroring or RAID
? The system is not pushed for space so mirroring is an option if there is
a reason for doing that, otherwise either approach works fine for this
install.

I normally prefer to hot spare RAID sets these days and I guess I could do
a 3 disk RAID set and hot spare it (not my preference...) but in that case
it seems to me MIrroring would probably be a better approach.

Any opinions as to which approach is better ?
