This portable PC has an HDD storage medium, which is the most commonly found storage medium on many processor core portable PCs that have been on the market for around the same time as it. HDD is a traditional storage drive which stores the information on magnetic disks. HDD drives are slower than other forms of storage such as solid state drives (SSD) and flash drives.
It may also be worth also looking at one of the alternative portable PCs that have an HDD storage media currently available including the DELL XPS 15 which is cheaper.
If the storage medium of this portable PC is too bad for you then you might also want to consider the EliteBook 755 (SSD and cheaper), or the ZBook 15 (SSD and cheaper) both from HP.
