The ThinkPad X250 has an SSD storage media which is better than the HDD storage media found on most medium processor cores portable PCs that have been around for around the same time as 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.
This laptop's storage medium (SSD) is actually the best storage medium amongst all medium processor cores portable PCs that have been available for a similar time to the ThinkPad X250.
An HDD storage media is the worst storage medium amongst similar types of laptop.
We compared this portable PC to all the other laptops that have an SSD storage media and we think because of it's better review score, the DELL Latitude 12 E7250[plb_2899678_price] is also worth considering.
