The Yoga 2 11 has an HDD storage medium which is better than most laptops that have been on the market for more than two years. Most portable PCs of a similar spec and age to it have an SSD storage medium. HDD is a traditional storage drive which stores the information on magnetic disks. HDD drives are slower than other forms of storage such as solid state drives (SSD) and flash drives.
An HDD storage medium is in fact the worst storage medium amongst all portable PCs of a comparable spec and age to the Yoga 2 11.
An SSD storage medium is the best storage medium amongst similar types of portable PC.
If the storage medium of this 2 in 1 laptop is too bad for you then you might also want to consider the Fujitsu Stylistic Q702 (£543.00) (SSD) which is also cheaper.
