What are the Sleep mode and Hibernate mode which is the best power saving mode??

Hi! 
 In this post, I am talking about what is the sleep mode and Hibernate mode in Computers and what is the best power saving mode?  whether if  you are using laptop or PC Desktops whatever.

ok let's  get started 

First, we gonna talk about what is a sleep mode 

In most of the Windows machine, you can see the sleep button on your start menu and other function + F1 key (It may be changed by the Manufuture)

When you click the sleep button your computer's current running process and programs are going to resume state. Cleary says these are  going to RAM the computer primary storage 

In the Computer storage side, the RAM accessing speed is the second fastest Storage media, First is Cache probably you know.

The typical RAM accessing speed was 1GB per second.. if you are using latest Model DDR4 RAM it may vary.

So when you press your sleep button. at that time your all current programs process files or resumed, that's are stored in RAM drive 
when you press any key on your machine immediately programs are backloaded on your machine within a fraction of seconds.

Note if you are using DDR4 RAM  and other fastest RAM technology, your sleep mode and return mode are extremely fast.

Ok, let's  Know on an important aspect in sleep mode. The RAM  is not a Nonvolatile memory.  you know very well the volatile memory lose the all data  If your Electricity goes off

The sleep mode use very limited power supply compared to your general ideal machine state.

The Next  is a Hibernate mode this mode is pretty much like a sleep mode
but in Your process files or stored in Hard disk Secondary storage device instead of RAM.

The advantage of this method, the files are put on the Hard disk these are a Nonvolatile memory storage device. so you can unplug your electricity. your process will not be lost. 

And another thing that in this mode and backloaded process speed really depends on your  RPM speed of Hard Drive.
if you are using SSD (Solid-state Drive) as your boot drive you hibernate and retrieve mode is extremely fast compared to mechanical hard drives 
If your an SSD you can choose the Hibernate mode for your Power saving option instead of Sleep mode. the time taken is not a major difference.

If you buy a new SSD the best buy links are here

Ok let's know what is the best power saving mode compared to these two options

 first of all the sleep mode is good for who is just turn off your process in very short time like Your tea break :) 

Or If you want to turn off your processes long time more than hour 
 you will choose the hibernate  mode

On the hibernate mode your computer goes on nearly zero power mode.

Ok thanks, guys I hope this post is really helpful for what is the sleep mode and Hibernate mode and what is the best power saving mode
