5 Hard disk drive (HDD) or solid state drive
Your computer may have a large-capacity, customer-upgradable hard disk drive that can meet a variety of
storage demands. To keep the drive safe, Active Protection System™ is installed on your computer. For
details, refer to "Active Protection System" on page 18.
With Lenovo technologies advancing to provide you with the best engineered systems, some models
are equipped with a solid state drive for data storage. This cutting-edge technology enables notebook
computers to be lighter, smaller and faster.
Note: The hidden service partition is the reason why there is less free space than expected on your hard
disk drive or solid state drive. This reduction is more noticeable on the solid state drive because of its
smaller capacity.
