Understanding Hard Drives (HDD): The Classic Storage Solution
A hard drive (HDD) is a non-volatile data storage device that stores and retrieves digital information using rapidly rotating platters coated with magnetic material. It is a traditional form of storage that has been a staple in computers for decades due to its high storage capacity and relatively low cost. Hard drives are ideal for storing large volumes of data, such as documents, photos, videos, and backups. While they are slower and more prone to mechanical failure than modern solid-state drives (SSDs), their affordability and capacity make them a popular choice for bulk storage in desktop computers and servers.
