Properly-functionioning spinning disks haven't had issues with random data loss on power failure for at least a decade now.
Source?
And your impression of cheap SSDs is dead, flat wrong. They're cheap - every unnecessary part is left off to save money. And we've all (all of us who pay attention) known for years that SSDs (even some with power fail protection) will lose data (even bits which it has reported to have sync'd) on power loss.
I think you misread what I wrote. I wrote that I would expect cheap SSDs to "survive a power loss event without being bricked." I did not write that they would retain all data, which seems to be what you are arguing against.
I have heard rumors that some cheap SSDs do not honor the SATA SYNC command. Unfortunately I do not have a reliable source for this theory, do you?
A UPS is not enough, if you need to have your data, you need multiple layers of backup, and an SSD must have some method of writing out voltatile data (mostly internal metadata, not cache) before it shuts down.
I don't think anyone is arguing that a UPS is a replacement for backups.
