kiintolevystä

Kiintolevy, often referred to as a hard disk drive (HDD) in English, is a non-volatile data storage device used for storing and retrieving digital information. It consists of one or more rigid, rapidly rotating disks (platters) coated with a magnetic material. Data is written to and read from the disk using a read/write head that moves across the surface of the platters.

Kiintolevyt are commonly used in computers, servers, and other electronic devices for storing operating systems, applications, and user data. They offer high storage capacity and relatively low cost per gigabyte, making them a popular choice for mass storage. However, they are slower than solid-state drives (SSDs) in terms of data access speed and have a higher risk of physical damage due to their moving parts.

The capacity of a kiintolevy is typically measured in gigabytes (GB) or terabytes (TB), with capacities ranging from a few gigabytes to several terabytes. The speed of a kiintolevy is measured in revolutions per minute (RPM), with common speeds being 5400 RPM and 7200 RPM. The interface used to connect a kiintolevy to a computer is typically SATA (Serial ATA), although older systems may use PATA (Parallel ATA) or SCSI (Small Computer System Interface).

In recent years, kiintolevyt have been largely replaced by SSDs in many applications due to their faster data access speeds and lower power consumption. However, kiintolevyt still have a role in certain applications, such as archival storage and backup, where their high capacity and low cost make them a suitable choice.
