HDD
(Hard Disk Drive)
An HDD (Hard Disk Drive) is a traditional storage device that uses magnetic platters and a moving read/write head to store and retrieve data. Unlike SSDs, which rely on flash memory, HDDs are mechanical devices with slower read/write speeds but offer higher storage capacities at a lower cost per gigabyte.
HDDs are commonly used in data centers, desktop computers, and external storage solutions where large storage space is prioritized over speed. While SSDs dominate performance-critical applications, HDDs remain relevant for archival storage, backups, and bulk data storage due to their cost-effectiveness. Modern HDDs use technologies like SMR (Shingled Magnetic Recording) to increase density, though they are increasingly paired with NVMe or SSD caching in hybrid systems to balance speed and capacity.
