Key Differences
An HDD, or Hard Disk Drive, is a data storage device that uses spinning disks to read and write information. On the other hand, an SSD, known as Solid State Drive, employs flash memory for data storage, without any moving parts.
The HDD has been a staple in computing for many years, recognized by its characteristic whirring sound when in operation. Conversely, the SSD operates silently as it doesn't rely on mechanical movements.
The HDD typically offers more storage for a lower price, making it a popular choice for large-scale storage needs. However, the SSD boasts faster data access speeds, leading to quicker boot times and faster application launches.
