Kiintolevyt, also known as hard disk drives (HDDs), and solid-state drives (SSDs) are both types of non-volatile storage devices used in computers and other electronic devices. They serve the primary function of storing digital data, including operating systems, applications, and personal files. The fundamental difference between them lies in their underlying technology and how they access data.

Hard disk drives employ magnetic storage technology. They consist of spinning platters coated with a magnetic material. Read/write heads move across the surface of these platters to access and record data. This mechanical operation means HDDs have moving parts, which can lead to slower data access speeds, increased susceptibility to physical shock, and a higher power consumption compared to SSDs. However, HDDs generally offer a lower cost per gigabyte, making them a popular choice for mass storage solutions.

Solid-state drives, on the other hand, utilize flash memory chips. They have no moving parts, which translates to significantly faster data read and write speeds, quieter operation, and greater durability against physical impact. SSDs also consume less power. While SSDs have historically been more expensive per gigabyte than HDDs, their prices have been steadily decreasing, making them increasingly common as primary boot drives for operating systems and frequently accessed applications where speed is paramount.
