The HP 840 has an HDD storage medium which is faster than most latest many processor core personal computers. Most PCs that have been on the market for around the same time as it have an SSD storage medium. 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 desktop computer and we think cheaper computers such as the DELL Precision T7810[plb_3704050_price] is also worth considering.
If you would prefer a PC with a faster storage speed then you might also want to consider the Z440[pl_3194686_price] (SSD), or the Z640[pl_3351639_price] (SSD) both from HP.
