The HP 2570p has an SSD storage medium which is better than most notebook PCs of this type and age. Most comparable spec laptops that came out around the same time as it have an HDD storage medium. 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 amongst all notebook PCs that are a comparable age to the 2570p.
An HDD storage medium is the worst storage medium across similar types of notebook PC.
If the storage medium of this medium processor core notebook PC is too bad for you then you might also want to look at the T420s (£1,388.87) (SSD), or the S540 (SSD) both from Lenovo.
