The HP 400 G3 SFF has an SSD storage medium which is faster than the HDD storage medium found on most computers that have been available for around the same time as it. 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.
An SSD storage medium is in fact the best storage speed amongst all new medium processor core PCs.
An HDD storage medium is the worst storage speed amongst comparable types of personal computer.
