Only HDD Storage Medium

The storage speed of this personal computer is HDD, which is the most frequently found storage medium on medium processor core personal computers that have been on the market for around the same time as it. A Hard Disk Drive (HDD) is the traditional storage method for computers. A HDD stores the information on magnetic disks. HDD drives are cheap, but they are slower than Flash and SSD bases storage systems.

We compared all the other HDD PCs to this desktop computer and we think the Lenovo ThinkCentre E73[plb_2338866_price] which is cheaper is also worth considering.
