Why is disabling hibernation recommended for desktop PCs?

Are there any technical benefits beyond saving disk space, considering that it also disables Fast Startup and Hybrid Sleep?

There are some solid technical reasons besides reclaiming disk space:

1. Fast Startup hibernates the Windows kernel and driver memory rather than terminating them. Any driver instability or memory leak survives shutdowns until you do a manual Restart. Disabling hibernation guarantees every boot starts from a clean slate.

2. When hibernation or Fast Startup is active, Windows doesn't cleanly unmount the drives. If you dual boot Linux or use recovery tools, mounting that drive can cause metadata and file corruption.

3. Fast Startup was engineered for mechanical HDDs. On modern NVMe SSDs, the boot time difference is 1 to 2 seconds at best, but you are writing 10+ GB of kernel state to your SSD on every shutdown. Because desktops are plugged into wall power 24/7, you never need the battery drain protection of Hybrid Sleep either.
