What is the difference between SATA, SSD and HDD?
SSDs are computers’ built-in hard drives, while HDDs are external.
SSDs store data in chips and run on a memory type called “flash”. Unlike HDDs, which make a physical head arm move to read/write the information, they work by blocking sections of data and zipping it along lines when needed. HDCo means you can access any section quickly whereas with a HDD all the sections will be located at the end of the chain.
Altogether there is less power consumption and no noise but much more expensive than your regular disks
HDD vs SSD
SSD stands for ‘Solid State Drive’. Essentially an SSD is a computer’s built-in hard drive that replaces mechanical parts (a slot where data is stored on disks that spin at thousands of revolutions per minute) with memory chips. This means that no moving parts are involved, they use less power, they generate less heat and are silent.
HDDs work by moving an arm with a reading head to different parts of the disk where information is stored. The information itself is stored on disks that spin at thousands of revolutions per minute.
HDDs are cheaper than SSDs because they use physical moving parts. They are therefore more reliable than SSDs, but use more electricity and generate more heat.
