My 2009 Mac Pro is getting long in the tooth. IGGY still works just fine of course I feel the need for speed. I don’t want to replace him with a garbage can. No matter how many cores and Thunderbolt ports they have, they only have one storage unit. The base model has 256 GB of PCI-E-based SSD, and I need at least two units of 1TB each. (One for normal use, one for CarbonCopyClones).
