The LG 13Z940 has an SSD storage medium which is better than most medium processor core laptops that were launched more than a year ago. Most medium processor core laptops that have been available for around the same time as 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 laptop's storage medium (SSD) is in fact the best storage medium across all portable PCs of a comparable spec and age to the 13Z940.
Across similar types of laptop the worst storage medium is HDD.
We compared this portable PC to all the other portable PCs that have an SSD storage media and we think the Asus UX305FA, the Lenovo L450, and the DELL Latitude 12 E7240 which is cheaper is also worth considering.
If the storage medium of this LG portable PC is too bad for you then you might want to look at the Asus UX301LA (SSD).
