Drives

There are two main types of drives:

HardDrives:

Hard drives are cheaper that SSDs and that's about it. They contain moving parts so they are more unreliable and they are also slower than SSDS

Solid state drives:

SSDS are more expensive than hard drives, a 2TB hard drive would be £60 whereas a 2TB SSD would be £300. But SSDS are more reliable and quieter as they have no moving parts and they are a lot faster. They are also physically smaller.


SSDs are becoming more popular, a lot more computers are coming with SSDs. The biggest computer maker in the world, Apple uses SSDs in many of its products.
Though before the costs come down even further, which they have been doing, hybrid drives can be used. Hybrid drives have a large hard drive, typically 1tb and around 7gb of flash. The programs you use most often are put in the flash while the rest are put in the hard drive.
