Nowadays, SSD disks are more and more common, especially for laptops, as they are by nature shock proof.
Even if they don't offer the same price per Gb than standard hard disk, they provide a fantastic performance boost and are more and more affordable.

- their very fast read and write speed
- their neutrality to random access
- their limited write cycles
