My 2008 Early MacPro3,1 has been fine running LR 6.8 - but with 24 and 34 mp RAW editing it is begining to take more time. The MacPro is: 2x2.8 Intel processor, Mem-16GB,Graphics Radeon HD 5770 (hard to find faster cards that fit). Anyhow, the MacPro has internal HD's: a 1TB HD for just for the Mac OS and LR and a few applications plus my LR Catalog; a second 3TB HD for LR photos and a third 3TB HD as a back to the LR photo drive - all drives are internal to the 2008 MacPro. Plus another 2GB internal drive w/Aperture images, and an external LaCie 1TB with odds and ends. So, I am considering about upgrading to a new MacPro - cost not an issue. But it seems that I will need to pull out the two 3TB HD's and the one 2GB drive and put them into a "cage" of some sort, then cabling to the MacPro Trash Can. Plus transferring everything on the 1TB HD onto the new MacPro which I can do with Macs transfer procedure.
But -I am unsure of how to go about this efficiently as possible and what possible "cages/systems" are the best to use and will interconnect easily.
I forgot to mention that perhaps an iMac might be the better choice! My NEC monitor is great, but then I am looking to make a new start with my current equipment. The Retina screen - well perhaps.
As always, LULA forum experience and opinions would be of help to me.
