SSD VS HDD

Access time	An SSD has access speeds of 35 to 100 microseconds, which is nearly 100 times faster. This faster access speed means programs can run more quickly, which is very significant, especially for programs that access large amounts of data often like your operating system.	A typical HDD takes about 5,000 to 10,000 microseconds to access data.
Price	The price of a solid-state drive is higher than an HDD, which is why most computers with an SSD only have a few hundred gigabytes of storage. Desktop computers with an SSD may also have one or more HDDs for additional storage.	HDD is considerably cheaper than SSD, especially for drives over 1 TB.
Reliability	The SSD has no moving parts. It uses flash memory to store data, which provides better performance and reliability over an HDD.	The HDD has moving parts and magnetic platters, meaning the more use they get, the faster they wear down and fail.
Capacity	Although there are large SSDs, anything over 1 TB SSD is usually outside of most people's price range.	Several terabyte hard disk drives are available for very reasonable prices.
Power	The SSD uses less power than a standard HDD, which means a lower energy bill over time and for laptops, an increase in battery life.	With all of the parts required to spin the platters, the HDD uses more power than an SSD.
Noise	With no moving parts, SSD generates no noise.	With the spinning platters and moving read/write heads, an HDD can sometimes be one of the loudest components in your computer.
Size	SSD is available in 2.5", 1.8", and 1.0", increasing the available space available in a computer, especially a desktop or server.	HDDs are usually 3.5" and 2.5" in size for desktop and laptops respectively, with no options for anything smaller.
Heat	Because there are no moving parts and due to the nature of flash memory, the SSD generates less heat, helping to increase its lifespan and reliability.	With moving parts comes added heat which can slowly damage electronics over time, so the higher the heat, the greater the potential for wear and damage.
Magnetism	SSD is not affected by magnetism.	Because a hard drive relies on magnetism to write information to the platter, information could be erased from an HDD using strong magnets.
