This laptop has an HDD storage medium, which is typical of many laptops that have been on the market for a similar time to 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.
There are a number of alternative portable PCs that have an HDD storage media currently available which you might want to consider including cheaper laptops such as the Lenovo B5400, or the DELL Latitude 14 E5450.
If the storage medium of this notebook PC is too bad for you then you might want to consider the Lenovo ThinkPad E550 (SSD and cheaper); or the LG 13Z940 (SSD and higher rated).
