Types of hard drives: 1. Mechanical hard drive (HDD) - The earliest and most widely used type of hard drive, which stores data primarily through magnetic principles, consisting of one or more rotating disks, read-write magnetic heads, spindles, motors, and other components. 2. Solid-state drive (SSD) - A type of hard drive that uses flash memory technology to store data. Compared to mechanical hard drives, SSDs have no moving mechanical parts, resulting in higher read and write speeds and stronger durability. 3. Hybrid hard drive (HHD) - A combination of mechanical and solid-state hard drives, integrating the advantages of both. It typically uses SSD storage chips as a cache to improve data read and write speeds, while the main data is stored on a mechanical hard drive. Characteristics of various hard drives: Mechanical Hard Drive (HDD): (1) Large storage capacity: Compared to other types of hard drives, mechanical hard drives offer a larger storage space. (2) Lower cost: Due to mature technology and widespread use, the manufacturing cost of mechanical hard drives is relatively low. (3) Higher power consumption: Due to the operation of mechanical components. Solid-State Drive (SSD): (1) Fast read and write speeds: With no mechanical moving parts, SSDs have significantly faster read and write speeds than mechanical hard drives. (2) Strong durability: SSDs are more resistant to shock and vibration, making them suitable for use in harsh environments. (3) Low power consumption: Although the manufacturing cost is higher, they are more energy-efficient when in operation compared to mechanical hard drives. Hybrid Hard Drive (HHD): (1) Good overall performance: Combining the advantages of both SSDs and HDDs, offering high read and write speeds with a large storage capacity. (2) Moderate price: While slightly more expensive than single-type hard drives, the overall performance and cost-
