The main reason is that there are no moving parts in an SSD, while HDDs have a lot of small moving parts, making them more prone to failure. Because there are no moving parts in SSDs, this makes them much faster than traditional HDDs. Also if any file gets corrupted on the SSD you can just delete it and write over it again with new data, but with an HDD if you accidentally lose a file you would most likely not be able to recover it.
Another thing about having no moving parts is that when power suddenly shuts off even when plugged into battery backup units (UPS) or surge protectors hardware will shut down before anything becomes corrupt unlike in HDDs where they might become corrupt due to sudden power outages.
Lastly, they are faster because of how storage works with HDDs, the computer needs to read the data through multiple layers of hardware until it can reach your required data layer.
However, most SSDs have data stored in NAND flash which is much faster than RAM so fewer memory layers need to be passed before you can access your files. This makes them slightly more expensive but their speed and reliability make up for this lack of cost-effectiveness.

How do data storage devices work?
Data is stored on disks with magnetic coating, the most common ones being the hard disk drives (HDD) and the solid-state drives (SSD). The SSD contains no moving parts allowing it to be more reliable than the HDD.
The HDD consists of a metal enclosure that houses one or more rotating metal disks coated in magnetic material together with electronic circuits for reading and writing data. When electricity is provided to these circuits it creates electromagnetic fields which are used to write data onto specific points of the platter by changing its polarity.
These plans are read by heads located at an arm above them, each head reads different parts of the disk when activated. Each head operates at a certain speed, measured in “revolutions per minute” (RPM), but newer drives have multiple heads to read and write data twice or even thrice faster.
What is the difference between HDD and SSD?
The biggest difference between them is probably how they store data. A hard disk drive uses magnetic storage while a solid-state drive uses flash memory to store data. The advantage of using flash memory is that it makes it much faster than relying on an electromagnet because this creates resistance which slows it down especially when writing onto disks.
Another big difference is how reliable they are, since there are no moving parts, solid state drives are more reliable than traditional hard disk drives because there is less chance for data corruption.
How long will it take to load a game on an SSD?
The answer for this question depends on the type of SSD and what other programs are running in the background. Solid-state drives operate at much quicker speeds than traditional hard disk drives, but they still run slower than RAM which is used by modern computers to store frequently accessed data. This means that while the operating systems and other programs may start up faster, games and applications will take longer to load because they need more memory power compared to the higher speed ability of solid-state drives.
Nevertheless, if your computer does not have multiple gigabytes worth of RAM you should get an SSD because it helps any device with faster booting time and program opening speed. The main advantage of having an SSD is that it can make your computer feel much faster because if you are currently using a traditional hard disk drive, the speed at which data is received will be slower due to HDD vs HDD differences.
What happens when you delete files on an SSD?
When dealing with solid-state drives there are no “records” like with magnetic storage.
All data that needs to be read or written onto the memory must go through specific points on the chips called “pages”. This means that if you accidentally delete something you can just write new information over top of it, but this process might take up more space than was used by the original file so depending on what program or type of data was deleted, you might lose a little bit.
How do hard disk drives work?
To read and write data onto a hard disk drive, there are several components that must be present including a spinning platter which is covered with magnetic material on the surface as well as a “slider” which can move from side to side allowing it to read different parts of the disk as they become available.
Below this slider, there are two metal arms that house one or more electrical circuits for sending information or reading it from memory together with an actuator motor attached to these arms by screws called “actuator screw threads”. The arm positions are controlled by the computer using specific commands sent by an arm positioning controller.
What happens when you don’t use your hard disk drive for a long time?
When you do not use a traditional hard disk drive, most of its parts will be stationary and therefore it will require almost no power to operate causing the drive to spin down and eventually go into an energy-saving mode that turns off all non-essential components such as motor spindles or actuator arms which are responsible for moving read/write heads across the magnetic surface of the spinning platters.
However, in some cases, these spindles may have been designed with a flywheel mechanism allowing them to continue spinning even while the rest of the system is turned off so there might still be enough power being supplied to maintain the spinning platters.
The time it takes before your hard disk drive goes into energy saving mode depends on how often you use your computer and other factors like if it is hot or otherwise unstable, but in most cases this will happen after 2-3 hours of non-use.
What is write amplification?
When data is written onto a magnetic storage device like an SSD or HDD, there are several areas that need to be covered by these ones and zeros while the rest remains untouched.
However, when moving between empty spaces to where the data lies, the actuator arms must perform “seek operations” followed by “write operations” which put wear and tear on traditional HDDs causing them to wear out faster.
Write amplification is also used to describe how much time it takes for the HDD to perform these operations which differs from device to device so you should take this into account when deciding on what kind of hard drive to buy.
What happens if my hard disk drive goes bad?
If your hard drive fails rendering it useless, you can still get all your data back by buying a new one and transferring all your information via super-fast SSDs or conventional HDDs using cloning software like Macrium reflect free.
This program will scan any existing disks inside your computer including operating system drives as well as secondary storage devices like USB ports, smartphones or removable media cards after which you are given 2 options.
The first allows users to create an image of their existing disks onto another one while the second allows users to restore their disk images back onto their original drives.
