NAS Configuration

[Enquiries]

I am considering setting up a NAS system for Video Editing. I work on a multitude of projects from Social Media to Feature films. I'm currently working on various external drives. Now that I have about 5o or so different HD floating around (1Tb-24Tb), I want to consolidate most of them into one source. I was for the longest time considering the Sandisk Shuttle XL but noticed that I can build out a NAS system for half the cost (if not less), but I'm not familiar with a NAS system setup. There are a lot of variables that I am unsure of. In my research, for video editing, everyone seems to point to Synology DS1621/1821, which has a few nice expansion units. I'm thrown however by the 10Gb ether cards, they have 4 for the device, no idea which is best. Not to rattle on about the device I'm leaning towards considering I'm still budgeting. Considering I'm working with everything from 1080p to 4k and I am still unsure about the throughput with 4k files (but I'll probably work mostly with proxies) and I am also confused with the cache and how that could affect my workflow, does it need to be added/upgraded? What would be the best raid setup for video editing?

I'm mainly working on a MacPro 2019, (96Gb ram/1Tb SSD/3.2GHz 16 core Intel Xeon W processor/Two Radeon Pro W5700X) I have various other computers that will be connecting, Macbookpro an iMac, and possibly one windows machine.
