HDD vs SSD vs SSHD





    HDD(Hard disk Drive):


Hard disk drive

      HDD is an traditional storage device which we are using for a long time.we might have seen the specifications of an HDD like 5400 rpm and 7200 rpm it contains a head and many revolving disks.These disks rotates he given rpm specified and collects data 

          Advantages:

             1.Comparing with SSD,HDD is cheap
             2.It is available in larger capacities 
             3.Easily available in market.
           Drawbacks:
       
             1.As it is a mechanical device there is a chance of wear and tear 
             2.Prone of damage(if it fell down from our hands the hard drive will corrupts and data                      loses
             3.Less speed,just because it is a mechanical device every time it has to rotate to get to the                   required data in the disks takes more time.
            4.Power consumption-as it is a mechanical device and it contains movable parts so it has                   consume more power to work.

What is SSD?:

SSD (Solid state drive)

            Solid state drive means it is in solid state it doesn't contain any moving part it made by the semi-conductors just like RAM based on flash.

        Advantages:
            
            1. Speed is more compared to any other Hard drive and we will get good performance
            2.Resistant to shocks-which means unlike HDD it doesn't have any mechanical parts it                       can easily sustain for falls.
            3.Power consumption is very low.
            4.Long life span because there is no case of wear and tear.
        

        Drawbacks:
        
            1.Cost is more as compared to a normal hard drive.
            2.Low storage capacity as compared to hard drives.
         

Now comes SSHD:



SSHD (Solid state Hard drive)



            You might have heard about some 64GB of SSD and 1TB of HDD whenever we purchase a laptop or a desktop actually what happens here is the operating system is stored inside the SSD because whenever we try to turn on our system it takes very less time to boot as SSD is fast.And we can store the remaining program files inside our HDD.

     if you want to upgrade your system we can just update our SSD because it helps to increase the speed of accessing data from memory to the CPU increases which helps to process the data faster .
