SSD(Solid State Drive) is actually a generic term for all kinds of storage which doesn’t have any moving parts(hence solid).
Instead of storing data on a spinning disk, they store data on chips, which are more responsive and only “age” when data is written to them. Meaning that SSD’s usually last longer than HDD’s, unless you constantly overwrite the data on them.
The SSD type that probably most people are familiar with, is the ‘traditional’ 2.5 inch form factor below
These drives are about 2-3 times faster than HDD’s, making them the usual choice for the windows install, since windows will boot much faster. Some games also gain a benefit in faster loading times, although not all.
The speed of these SSD’s is really only limited by their interface connector; SATA, which had no reason for futureproofing, since it was made for HDD’s.
- Slightly more expensive than HDD’s
- Much faster than HDD’s
- Usually more reliable for longterm usage
