Bob -

Thanks for your reply, which has certainly moved me forward in the decision-making process, but yet leaves me still a little confused--

You say at first that I should use my 1TB boot HDD to house my software programs, but then go on to suggest that I buy 1 x 480GB SSD to house them on instead. Are you telling me that SDD, if used at all, is valuable primarily as a boot drive?

What about a scratch disk? Is that not the best use of an SDD? Can the boot disk also act as a scratch disk?

And is there any reason why you'd suggest 1 x 480GB SDD over 2 x 250GB SDDs in a Raid 0 configuration for this particular job? Isn't the latter around 2x faster in its read/write capabilities?

Are you suggesting that I buy an external Raid array and connect it to my Mac Pro using a PCI Raid controller?

So many questions, forgive me if the answers are relatively self-evident!

From what I gather from your post, you suggest:

1 x 480GB SSD for boot / software (and scratch disk?) use
External RAID array of HDDs for storage.

Would this provide me with not only a clean, empty and fast scratch/boot disk from which to operate day-to-day as well as reliable long-term storage?

Thanks again.
