What is an SSD?
A solid state drive or SSD is a digital storage option where your data is saved on a microchip and sometimes, depending on the size, many microchips. Instead of the data being saved on a moving disk like an HDD, and SSD us many microchips that bundle to make your drive.
A SSD is…
Without a spinning disk or any moving parts at all SSD are a lot quieter.
Once again with out the need to spin a disk to gather data instead all the data is connected to the computer at the same time, compared to a HDD which can only read at the speed that the laser and disk can move.
With no mechanical parts like the disk spinner and head of an HDD these chips can be manufactured smaller making them ideal for slimmer mobile computers like the MacBook.
4. Generally last longer
Just like the other three with less moving parts less can go wrong.
5. Use Less Power
No moving parts of an SSD use less power than an SSD because there is no disk to spin and no laser to burn. Although most drives will need a power source other than your computer if it is not made to be portable.
