The Acer M1-601 has a Flash storage medium which is faster than most PCs of this type and age. Most few processor core personal computers that have been on the market for a similar time to it have an HDD storage medium. Flash Drives 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. Across all personal computers of a comparable age and type to the M1-601 the best storage speed is SSD and the worst is HDD.
If you are looking for a desktop computer with a faster storage speed then you might want to look at the HP Chromebox[plb_2305242_price] (SSD).
