Before getting into SSD vs HDD differences let us understand what SSD means.SSD stands for Solid State Drive. You can think of it as a bigger version of a flash drive. There is no moving part in an SSD like HDD. Information is stored in microchips. SSD has an embedded processor also known as the controller that performs the operation of reading and writing data. Most of the time the operating system is installed on an SSD which makes the booting of the computer faster. A hard disk drive uses a mechanical arm with a read/write head to store and read information on the storage platter. This is the reason why SSDs are faster than HDDs.

H D D (Hard Disk Drive)

HDD stands for Hard Disk Drive. The history of HDD goes way back. HDDs were introduced by IBM in 1956. HDDs have storage disks also known as platter that rotates rapidly. A mechanical arm reads and writes the data into the platter. There is a lot of mechanical process going on which makes the HDDs slower than SSDs.
The advantage of HDD over SSD is that it is available in large capacity and is cheaper. For example, WD Blue 1TB HDD costs around 3500Rs and Samsung 850 EVO 250GB SSD costs around 8000Rs. This cost difference is huge. So now let us compare the key factors for the SSD vs HDD
SSD vs HDD performance, Speed

Factors

1.Power Consumption

HDD

Consumes more power.
Average 6-7 watts.

SSD

Consumes less power.
Average 2-3 watts.

2.Operating System Boot Time

HDD

Around 30-40 seconds average.

SSD

Around 10-13 seconds average.

3.Read Write speed

HDD

Average speed is around 60MB/s to 160MB/s.

SSD

Average speed is around 200MB/s to 500MB/s.

4.Noise

HDD

The mechanical arm and the platter moves rapidly which makes a lot of noise.

SSD

There are no moving parts, so no noise produced.

5.Storage

HDD

Maximum storage is 10TB

SSD

Maximum storage is 4TB.

6.Cost

HDD

Cheaper than SSD

SSD

Very Expensive
