The ProDesk 600 G1 has an SSD storage medium which is faster than most PCs that have been around for a comparable time to it. Most medium processor core PCs that have been available for a similar time to it have an HDD storage medium. 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 personal computer's storage speed (SSD) is actually the best storage speed across all similar spec computers that came out around the same time as the ProDesk 600 G1.
