Take this with a grain of salt, cause I did a rig upgrade not too long ago, and was accidentally shipped far more drives than I ordered, so my storage space is silly.
Instead of replacing the drive in your machine, maybe try getting a nas or something. You can store a lot of your files there and keep the drive in your rig for things that need to be fast, like games. Also, I usually base my storage increase purposes based on how much room I need for backups. If there isn’t enough room for me to do a full compressed backup, it’s time to add more. Besides that, I replace the drive with most of the other parts in one large upgrade.
I will not stand for this anti goblin propaganda >:(
