To assist in sorting this out we posed a number of questions to Annabelle Thuan, Lenovo SMB Marketing Manager. AM: What is the difference between SSD and HDD? AT: The main difference in the technology is that solid state is a flash-based storage and has no moving parts, while hard disk drives are electromechanical and have a moving component called a spinning platter.

SSD is much faster because it is NAND memory. This means that data can be located instantaneously by address. HDD, on the other hand, has a two-step process to access the information.
