kiintolevyä

Kiintolevyä, often referred to as a hard disk drive (HDD) in English, is a fundamental data storage device used in computers and many other electronic systems. Its primary function is to store and retrieve digital information persistently. The term "kiintolevyä" itself is Finnish and translates directly to "hard disk."

Internally, a kiintolevyä consists of one or more rigid, rapidly rotating platters coated with magnetic material. Data is read and written to these platters by a read/write head that moves across the surface of the disks. The platters spin at high speeds, typically ranging from 5,400 to 15,000 revolutions per minute (RPM), allowing the read/write head to access data quickly.

The storage capacity of a kiintolevyä is measured in gigabytes (GB) or terabytes (TB), indicating the immense amount of data it can hold. These devices are crucial for operating systems, applications, and user files. When a computer is turned off, the data stored on the kiintolevyä remains intact due to the magnetic properties of the platters, unlike volatile memory like RAM.

While solid-state drives (SSDs) have become increasingly popular due to their speed and durability, kiintolevyjä remain a cost-effective solution for mass storage, particularly in desktop computers, servers, and external storage devices where large capacities are required at a lower price point.
