This portable PC has an SSD storage medium, whereas most laptops that are a comparable age to 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.

Amongst similar types of portable PC the worst storage medium is HDD.
We compared all the other portable PCs that have an SSD storage media to this laptop and we think the HP EliteBook 840[plb_2320440_price], and the DELL XPS 13[plb_1304263_price] which is cheaper is also worth considering.
Notebook PCs with a better storage medium that might be worth looking at include the T420s[pl_48433_price] (SSD), or the X1[pl_1610908_price] (SSD) both from Lenovo.
