First difference is on power. Hibernate consumes zero power because all the system goes down to sleep while in standby except CPU and RAM all system sleep down. However, CPU and RAM consumes some power (1 to 6 watts) to remain in operative state.
Risk of losing the data in standby is high because it may happen that after gradually decreasing in power suddenly system can shut down automatically. So, all the unsaved data will be lost. There is no such risk of compromising on data in case of hibernate.
In boot back up of system, standby is much faster than hibernate.
In standby sleep mode, system wake up in a second after pressing any key or power button while hibernate takes some time (30 second to 2 minutes) to come back in original state.

Hibernate is that sleep option of Microsoft Windows OS, which saves the image of desktop by keeping all the files and documents in open state then goes for power down of computer. After then, whenever you turn on power, all your files and documents, that were in open state on desktop, presented before as it as they were left by you. Hibernate is the best technique to save the power because first it saves your RAM memory in hard disk and then shuts down the all system and saves as much power as it can. But there will be no effect on your opened files and documents because due to hibernate function all the memory of RAM memory will goes to hard disk and your files and documents will remain in open state when you will come back. It is suitable when your system is inoperative for a longer time and you do not bother to start it after shut down.
Standby is also a sleep mode option of Microsoft Windows OS and performs the same work as performed by hibernate but in different style. Unlike hibernate it does not shuts down the whole computer. In fact, it cuts down the power of peripheral devices, which are not in operative state along with monitor and hard disk, but keeps on the power of CPU and RAM. So, by this option system keeps all the open files and documents on desktop in default state and remain open when you will come back to your system again. After pressing any key or power button of system, your system will wake up within a second. Standby is most suitable option for booting. Boot back up of system can be better performed with high speed in standby mode.
