This laptop has an SSD storage medium, whereas most medium processor core laptops that were released one year ago 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.

We compared this laptop to all the other notebook PCs that have an SSD storage media and we think cheaper laptops such as the T450 ($999.00), and the T450 ($999.00) both from Lenovo or the HP EliteBook 840 ($600.00) is also worth considering.
