The Lenovo T450 has an SSD storage medium which is better than the HDD storage medium found on most medium processor core laptops that have been on the market 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.
This portable PC's storage medium (SSD) is actually the best storage medium amongst all medium processor core laptops that have been around for around the same time as the T450.
Amongst comparable types of portable PC the worst storage medium is HDD.
We compared all the other laptops that have an SSD storage media to this laptop and we think the Satellite Z30[pl_2363540_price], and the Satellite Z30[pl_2363540_price] both from Toshiba which has better reviews is also worth considering.
Portable PCs with a better storage medium that might also be worth looking at include the Lenovo T550[plb_2916140_price] (SSD), or the DELL Latitude 14 E7450[plb_2882106_price] (SSD).
