Hibernation VS suspending
Hibernation is unreliable, It writes to a swap partition reserved for system caching and temporary files.
It writes the operating system's current state to disk; all of its environmental parameters, programs, processes, etc. Frequently, there won't be enough disk space to store the computer's state preventing it from successfully returning from hibernate.
suspending
Suspending involves the operating system writing its state to the system RAM which is faster and generally more reliable, although it draws a little bit of power in order to keep the information stored in the RAM.
