The DELL 3050 has an SSD storage medium which is faster than the HDD storage medium found on most new computers. Solid State Drives (SSD) store information in transistors on a circuit board rather than on optical or magnetic media. This has the advantage of being much faster than a traditional HDD drive.
This PC's storage speed (SSD) is in fact the best storage speed across all few processor core computers that have been around for around the same time as the 3050.
An HDD storage medium is the worst storage speed across comparable types of PC.
