Apple (Late 2013) Intel 6-Core Mac Pro Workstation

The initial page says Late 2013 for the Mac Pros but the details page for them states Early 2013. The same specs on these Refurbs at Apple.com say Late 2013 so am assuming that is the right release date. I think they only released them one time and know they are so overdue for some kind of refresh…

They’re Late 2013. Titles will be corrected shortly.

any recommendations on external drives that are hardware raid 5 and hot swappable?

I see G-Technology and Pegasus both have external drives - any feedback would be great!
