Here is my new setup. I bought back at the end of November. My primary use is for editing 4K video from my drone and 360 degree photos and video from my GoPro Fusion. Are there any tips to maximize performance or tips to help keep my machine running as long as possible? iMac (Retina 5K, 27-inch, 2017) macOS High Sierra Version 10.13.3 4.2 GHz Intel Core i7 64 GB 2400 MHz DDR4 500 GB SSD Radeon Pro 580 8 GB External 3 USB3 slots with 27 card reader mounted under the iMac Displays (total of 3) 27-inch (5120 x 2880) (the iMac) Dual LG Ultra HD Display 27-inch (3840 x 2160) Storage Super Drive - I still haven't used it yet, but at least I have it. 500 GB Flash Storage (Macintosh HD) used for programs and stuff that stays on the iMac WD 8TB External HDD - used for every day storage such as pics, documents and stuff most people keep on their machines.. 1 TB External SSD (I forget exactly which one) - used for my work flow if all the footage is smaller than 1 TB 12 TB External HDD RAID 0 - used for my work flow if all material is over 1 TB; This runs pretty fast, but still nothing compared to SSD. Will upgrade to a large SSD RAID setup later this year. Backup I use BackBlaze. It backs up all of my iMac and 1 external (I have it backup my 8TB) Time Machine - I have a 4 TB WD My Passport I used for Time Machine because I also have an iMac at the office and a Macbook Pro, so I partitioned it and use Time Machine at least once a week on all machines.
