Good Morning, I am somewhat new to a MAC but not to Windows, Linux, and etc. as I am a DB System Administrator in a large health care organization. I am getting ready to order a fully loaded 27" IMAC with a 512 GB SSD. I am looking for advice on a high quality HD array (probably JBOD) where I can run 2-4 drives. One drive will be Time Machine, one will be used to images using CCC, and the others will be used for miscellaneous projects. My primary concern is quality and longevity. I have read so many threads, blogs, and etc. that I'm somewhat confused on what the top of the line products really are. I will probably opt for USB 3 as opposed to TB as since I don't plant to run RAID it will likely be just as fast and probably more cost effective. I would appreciate any advice that you could provide me in this endeavor. Thanks in advance!
