Before going to know the differences between HDD and SSD, firstly know about the working principle to understand clearly: HDD: Internal structure of HDD  Hard Disk Drives access or data with the help of moving parts inside it. HDD stores the data in the form of tracks and sectors. Tracks and sectors Accessing and writing data depends on the rotating speed of the disk inside it. SSD:   The solid-state drive works with the help of flash memory. It consists of a microcontroller and cache memory inside it. Internal structure of SSD Differences between HDD and SSD: 1.SSD is faster than HDD because HDD contains moving parts which has limitations whereas SSD has no moving parts and contains a microcontroller, cache memory which helps us to work fastly. 2.SSD requires less power consumption than HDD because SSD has no moving parts. 3.HDDs are more prone to damage than SSDs. 4.SSD is costlier than HDD. 5.Data durability(storing data for more time) is more in HDD than SSD.

Before going into the topic, let us know about the basic terms: Blackhole: It is a region in spacetime where gravity is very strong by which every particle and also light can't be escaped. WIFI -- Wireless Fidelity Have you known black holes are the reason behind the invention of wifi? In the later 1960s, Dr.John O'Sullivan and his teammates were working for CSIRO (Commonwealth Scientific and Research Organisation). As the blackhole release different types of radio signals they planned to collect them. To collect those signals Fourier transformed equation was introduced. But this was not successful. By this equation, they weren't able to collect signals from the blackhole. But later they want to use it in the computer networks, after trying different methods they succeeded in inventing Wifi. This is how Wifi is invented. The equation that was introduced for collecting signals from blackhole, it was used to invent Wifi later. Nowadays Wifi became very important to interact ...
