merevlemezen

Merevlemez, commonly known as a hard disk drive (HDD), is a non-volatile storage device that reads and writes data electronically using magnetic storage. It is a key component in most computers, responsible for storing the operating system, applications, and user files. The term "merevlemez" is Hungarian and translates directly to "rigid disk."

The core of a merevlemez consists of one or more rapidly rotating platters coated with a magnetic material. Data is stored by magnetizing tiny sections of these platters in different directions, representing binary ones and zeros. Read/write heads, similar to those found in tape recorders, float fractions of a millimeter above the surface of each platter, reading or writing data as the platter spins. The speed of rotation, measured in revolutions per minute (RPM), significantly impacts the drive's performance.

Merevlemezek have been the primary form of mass storage for decades, offering a good balance of capacity, speed, and cost. While newer technologies like solid-state drives (SSDs) have emerged, offering much faster performance and greater durability, merevlemezek remain popular for their high storage capacities at a lower price point, making them ideal for archiving large amounts of data or for use in less performance-critical applications. They are characterized by their mechanical nature, which can make them more susceptible to physical shock than SSDs.
