This portable PC's storage medium (HDD) is in fact the worst storage medium across all notebook PCs of a similar type and age to the Flex 15.
The best storage medium across comparable types of portable PC is SSD.
We compared this laptop to all the other portable PCs that have an HDD storage media and we think cheaper notebook PCs such as the Lenovo Yoga is also worth considering.
If you are looking for a notebook PC with a better storage medium then you might also want to consider the Toshiba Satellite U920t (SSD), or the DELL XPS 12 (SSD) which is also cheaper.
