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 considering one of the alternative laptops that have an HDD storage media currently available including the MSI GS70 which has better reviews.
If the storage medium of this portable PC is not good enough for you then you might also want to consider the AORUS X3 Plus (SSD) which is also higher rated.
