<human>:  What is the difference between a hard drive and a solid-state drive?
<bot>: The main difference between a hard drive and a solid-state drive is in the way they store and access data. Hard drives use spinning disks to read and write data and rely on physical components moving at high speeds to access the data. Solid-state drives use the same type of storage technology as computer memory (typically flash memory) and do not have any moving parts, making read and write processes extremely fast.
