The Asus Transformer Book T300 Chi has a better storage medium than most similar spec portable PCs that were released more than two years ago. This portable PC has an SSD storage medium, whereas most similar spec laptops that are a comparable age 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 notebook PC's storage medium (SSD) is actually the best storage medium across all similar spec notebook PCs that have been around for a comparable time to the Transformer Book T300 Chi.
An HDD storage medium is the worst storage medium amongst similar types of notebook PC.
If the storage medium of this medium processor core portable PC is too bad for you then you might want to consider the DELL XPS 13 (£491.96) (SSD).
