I got curious what the biggest disks are right now and gods... there's a 100TB SSD now. But it's absolutely not what I'd consider "accessible". Casual US$10,000 price tag.

26TB is the cap for spinning rust, and with HAMR tech being... hammered... out it looks like that's gonna bump up soon. Dunno how much I trust HAMR, but then again you'd be raiding this stuff in any real use-case (and have backups hopefully)

Reasonable SSDs? 16TB I guess. Still more than I expected, still ludicrously expensive though. Just not 10k bucks expensive.
@trysdyn in many cases, just getting couple less bigger one but a lot cheaper and raid them up is better ROI then whatever speed and price for one big one does imo 
@kazukidevnull Well yes, but the original point was "Can you fit everything emulate-able available on one hard disk" and the answer is "Probably" for that 100TB behemoth.

Closer to "No, but you can get everything but the most recent gens" for a more reasonable one. ;)
