HFS, APFS, FAT 32, ETC. I will be using for Plex storage only, and only movies. I may also use for file storage, but main use will be video. What is the best format option for this on a new iMac? Thanks.
best with HFS if only use on Apple products. APFS is more for SSD hard drive. If you want to use this on both Mac and PC then use FAT32.
