I have a laptop and desktop PC, both have 32GB of RAM. They each have a 2TB SSD to boot from and a 4TB SSD for media handling. Once I'm done editing, I offload to a pair of NAS servers, 4-bay, 4x 14TB drives with 1 drive redundancy, so it's 42TB each.
Then once in awhile, I back the NAS data to a bunch of externals.
But honestly, the still photography stuff takes up very little space. I think all the photos I have ever taken across 20 years only takes up about 10TB, and I output JPEG+RAW. Most of the pictures have been 36 mpx (D800) up to 60 (A7R4).
32 GB memory. LR catalog on a 1 TB Gen 5 M.2 SSD, Image files on an 8TB spinning disk. No issues at all with Canon R5 and R7 files, and I always have multiple files open. I have three backup drives in different places.
Saving layered files can be an issue with spinning disks. While working, I save as TIF uncompressed, and the save is quick. I archive as TIF with both file and layers compressed. This takes a minute.
