I'm about to buy a retina iMac and am trying to decide between 3 TB Fusion (which I have in current iMac) or 512/1 TB SSD + external TB (probably the OWC Thunderbay 4).
I've read that the read speed of the Fusion drive is very fast and difficult to match with an external drive set up, unless you use RAID-0 with 2-3 drives.
My question: what external configuration would I need to match the read speed of the Fusion 3 TB? I'm a little less concerned about write, because from what I've read read operations outnumber write by at least 10/1 for most activities.
