The EliteBook Folio 1040 G1 has an SSD storage medium which is better than most notebook PCs of this type and age. Most notebook PCs of a similar age and type to 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.
This laptop's storage medium (SSD) is actually the best storage medium across all medium processor core notebook PCs that were launched more than two years ago.
An HDD storage medium is the worst storage medium across similar types of laptop.
If the storage medium of this laptop is not good enough for you then you might want to consider the T420s (£1,388.87) (SSD), or the S540 (SSD) both from Lenovo.
