Memory-upgrade slots

Storage drive
Depending on the model, the computer might have a large-capacity, customer-upgradable hard disk drive
that can meet various storage demands.
Some models have a solid-state drive for data storage. The solid-state drive makes your computer light,
small, and fast.
Some models are equipped with a hybrid drive, which is a storage device that combines NAND flash
solid-state memory with hard disk drive technology.
Note: The hidden service partition is the reason why there is less free space than expected on your storage
drive. This reduction is more noticeable on the solid-state drive because of its smaller capacity.
