The storage speed of this PC is HDD, which is the most commonly found storage medium on desktop computers of a comparable age and spec to 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 personal computers to this computer and we think the DELL OptiPlex 3020 ($389.99), and the Asus VM42 which is cheaper is also worth considering.
If the storage speed of this HP PC is not fast enough for you then you might want to consider the Asus Chromebox (SSD and cheaper), or the Acer Revo One RL85 (SSD and cheaper).
