The ATIV Book 9 has an SSD storage medium which is better than the HDD storage medium found on most medium processor core laptops that have been around for more than a year. 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.
An SSD storage medium is in fact the best storage medium across all medium processor core laptops that were released more than a year ago.
Across comparable types of notebook PC the worst storage medium is HDD.
If the storage medium of this Samsung portable PC is too bad for you then you might want to consider the DELL Latitude 12 E7250 (SSD).
