The hard drive is where your software, documents, and other files are stored. The hard drive is long-term storage, which means the data is still saved even if you turn the computer off or unplug it.
1. Mechanical Disk
The so-called “traditional” hard disk. Has a motor and “read-write head”, thus rightfully called “mechanical”. Not that it is bad, it’s just heavier and less shock resistant.
2. Solid State Disk (SSD)
Has no moving parts, pretty much just a solid circuit board with a load of memory chips. Thus, rightfully called a “solid-state drive”.
3. M.2 SSD
As computers become slimmer and smaller, there is also a need to make smaller hard disks. The M.2 SSD is a variant of the “normal SSD” with a smaller footprint.
