Having some trouble deciding on what to do for storage to my new iMac. I ordered the iMac with 512 SSD because of 1 TB would still be to small and 2 TB toooo expensive =) I have a large Photos library of around 650GB today growing 80-100GB/year. And maybe more now when enabling 4K video on phones and camera. But mostly images so maybe not such huge difference. Maybe put videos outside of the library instead is an option. The Library today is on a Samsung Evo 1TB SSD in a UASP USB 3 chassi and achieves around 370-420Mb/s and is a huge improvement over the WD Duo 4TB Thunderbolt 2 I also have. Library is super smooth on the SSD. But now for the new iMac the WD Duo has to go and a new setup is a must! I have been wondering of maybe a ordinary USB 3 4-8TB (Usage 1-1,5TB) disc for just file storage and keep the 1TB SSD for photos and when it outgrows buy a RAID chassi and get another one. Time Machine is Backing up to Synology Nas. Anybody thinking of a better solution for me? Can a faster RAID HDD be similar to the SSD setup? Or is SSD just the way to go?
