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

In this case, I would mirror because you cannot create 2x parity
sets with 4 drives. Latency introduced by a single parity set
would cause your customer to question the investment in SSDs.
