Someone posted a graph and at current rates the cost per GB should converge around 2030 assuming current trends continue.
I figure sooner as i'd assume HDD costs will increase as the sales volume goes down
Almost all consumer goods are already SSD at this point.
Anytime a HDD goes out in anything at this point it gets replaced with a SSD.
Only things i'd stick with HDD for at this point is heavy storage like NVRs and backups.
Most modern laptops don't even have a place to put a HDD and I can't even complain about it you can put way more storage in a m.2 than you can in a 2.5" 9.5mm hdd.
HDDs will still be profitable for at least several years but it's pretty clear that SSDs are where the market is going.
The user profile directory? Almost everything is in there somewhere.
Not that it matters much. If the PSU went out and took everything with it i'd only lose a few hours work.
It'd be annoying but i'd probably be a lot more annoyed with having to replace the hardware.
It'd only take a few hours to restore from backup but it'd take several days to get a similar machine.
Realistically if this thing goes out i'm just going to spin it up in a VM on one of the other machines I have on hand until I can find a suitable upgrade to replace it with rather than trying to put it back like it was as it's long overdue to be replaced anyway.
