This laptop has an SSD storage medium, which is typical of many laptops that have been around for a similar time to it. 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.
We think you might also be interested in some of the alternative portable PCs that have an SSD storage media currently available including the X240[pl_2034037_price], or the X240[pl_2034037_price] both from Lenovo which is cheaper.
If the storage medium of this notebook PC is too bad for you then you might want to look at the XPS 13[pl_1474903_price] (SSD), or the Latitude 12 E7240[pl_1623520_price] (SSD) both from DELL.
