The HP EliteBook 2170p has an SSD storage medium which is better than the HDD storage medium found on most notebook PCs of this spec and age. Solid State Drives (SSD) store data in semiconductors on a circuit board rather than using magnetic or optical media. Solid State Drives have no moving parts which makes them very fast and reliable.
An SSD storage medium is actually the best storage medium across all similar spec laptops that have been available for more than two years.
An HDD storage medium is the worst storage medium across comparable types of portable PC.
If you are looking for a portable PC with a better storage medium then you might want to consider the DELL XPS 13 (£491.96) (SSD).
