I recently read that using Hibernate instead of shutting down can wear out an SSD because Windows writes the current session to disk. I usually hibernate my desktop every night so all my applications reopen where I left off, and I prefer it over Sleep because I can switch off the power strip while I'm away. Is the extra writing significant enough to worry about with a modern SSD?
I also saw older reports claiming that Hibernate could damage AMD processors, particularly early Ryzen 7000 systems on the AM5 platform. I've just upgraded to a Ryzen 7 9700X, so I'd like to know whether there's any truth to that or whether the issue was actually related to early motherboard BIOS and voltage problems.

The old AM5 CPU failures were associated with early Ryzen 7000 motherboard firmware and excessive SoC voltage, not Hibernate itself. Make sure the motherboard BIOS and chipset drivers are current and that the system is running sensible voltage limits. A Ryzen 7 9700X is not generally at risk simply because you use Hibernate.
The amount written during Hibernate depends on the system state and Windows configuration, but it usually isn’t equivalent to writing every byte of installed RAM. Even a pessimistic estimate would still be well within the endurance of a decent modern SSD over many years. Keep backups regardless, since protecting against drive failure is more important than avoiding this relatively minor wear.
Hibernate does write the current system state to the SSD, so it technically adds some wear. In practice, one hibernation write per day is very unlikely to make a meaningful difference with a modern SSD, especially compared with normal paging, application activity, downloads, and updates. You can safely keep using it if restoring your open apps is useful.
On a desktop, Hibernate is mostly a convenience feature. Sleep resumes faster, while a full shutdown or restart gives you a completely fresh session. That said, there’s no general reason to avoid Hibernate if it works reliably for you. SSDs are designed to handle substantial amounts of writing, and a daily hibernation image is normally a small part of the drive’s total endurance.
I was hesitant about Sleep because I’ve heard of computers waking unexpectedly, so Hibernate seems like the better fit for my routine.
That’s reassuring. I mainly use it so I can cut power at the strip overnight without losing my open applications.
