Maybe you see a usecase that would see someone without knowledge or equipment need tons of cheap storage in a single desktop pc?
Personally I have 4 TB and some in the PC, and it’s almost full. a few VMs, a couple of snapshots, music because I prefer a local player over jellyfin, almost all programs that I didn’t want to keep on my small SSD, and a bunch of other data.
I know someone who wanted to save his dashcam recordings to his PC. I could not get him to tell why does he want it, and figure out if it would be important enough to get a big drive, but currently he can only store 2 days of recordings on the SSD. People around me are often on a tight budget, and I didn’t want to buy him an SSD unnecessarily big (before I got to know he wants to do this…), both for the cost and the lower lifespan
I would rather not buy so large SSDs. for most stuff the performance advantage is useless while the price is much larger, and my impression is still that such large SSDs have a shorter lifespan (regarding how many writes will it take to break down). recovering data fron a failing HDD is also easier: SSDs just turn read-only or completely fail at one point, in the latter case often even data recovery companies being unable to recover anything, while HDDs will often give signs that a good monitoring software can detect weeks or months before, so that you know to be more cautious with it
