I'm looking to save large amounts of structured data - think coupons, recipes, ads, prices, etc. I'd like to be able to not have to worry about hard drives, so one thought was to save this in Github. However, the value proposition behind putting this in a SQL server is higher.
Have you stored large amounts of data before, how did you end up saving it?
However, if you tend towards curation more than me, you have categories, it might work for you.
I have a WikidPad personal wiki, in there are various things I've written over the past few decades, including the always elusive key to my WiFi.
My photos (600 GB) sit in folders D:\masterarchive\yyyy\yyyymmdd\ I never edit the originals, always save to a new file name when opening them in GIMP, etc. I have two short python scripts today.py and yesterday.py that make and open a new folder for me, depending on when I transfer the files from the SD card from my DSLR. You could make a script do it for you by reading the metadata from your smartphone photos.
SQL is a pain in the ass if you don't match the structures you set up initially. It's going to always be running, and will slow down a laptop or notebook boot time considerably. However, they do work well for tightly structured data.
