The YOGA 3 11.6" 2 in 1 has a better storage medium than most similar spec laptops that have been around for a comparable time to it. This Lenovo portable PC has an SSD storage medium, whereas most comparable spec notebook PCs that were released more than two years ago 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.

Across similar types of portable PC the worst storage medium is HDD.
If the storage medium of this medium processor core notebook PC is too bad for you then you might want to consider the T420s (£1,388.87) (SSD), or the S540 (SSD) both from Lenovo.
