DP,

Since you have the physical media anyways in the case of a catastrophic failure of the drives, do you really want the extra expense of going with a Lincoln cost solution when a Ford cost solution will do?

As much as I am a champion of data redundancy, at some point the cost of the solution far outweighs the risks of data loss.

Now if you're storing data for which no physical backup exists then yeah, I can see wanting the "all singing / all dancing" level solution.

Otherwise I say go consumer level and wait for solid state drives to mature and then go that route.

Just my 2 cents (plus GST/PST/HST where applicable)
