Solid State Drive (SSD) is a next-generation storage device used in computers. It uses flash memory to store data, which is much faster than the traditional hard drive it replaces. SSDs also have no moving parts, making upgrading to one a good way to speed up your computer and make it more flexible.
SSD stores data permanently in integrated circuits, usually using flash memory. Flash memory in the SSD means data is written, transmitted, and erased silently and electronically – no moving parts as found in a hard disk drive (HDD). With no moving parts, SSDs are fast and quiet, but they are more expensive than HDDs.
SSDs used to have less storage capacity than traditional HDDs, but now you can find SSDs (and HDDs associated with them) in almost any size you need. SSDs are usually used as auxiliary storage devices in high-end machines or consumer PCs.
Today almost all new laptops and desktop computers use SSDs to store non-volatile data (meaning that data stored persistently will not disappear when the device is turned off, unlike RAM). SSDs provide lightning-fast data storage and retrieval, and they are smaller and lighter than HDDs, providing greater design flexibility for computer manufacturers.
The adoption of SSDs began among PC enthusiasts and in high-performance technology fields, where their extremely short access times and high throughput justified the higher costs. But since then, they have become the standard storage drive type used in low-cost mainstream laptops and PCs.
Companies that deal with large amounts of data (such as programming environments, data analysis firms, financial companies) typically rely on SSDs because access times and file transfer speeds are crucial.
Computers optimized for gaming have constantly pushed the limits of current technology, opting for more expensive devices to enhance gaming performance. This is especially true for storage because modern games constantly load and write files (textures, maps, levels, characters). New gaming machines - like the PS5 and Xbox Series X - now use SSDs instead of hard drives.
SSDs have low power requirements, which helps extend the battery life of laptops and tablets. They also have shock resistance, which can reduce the chance of data loss when mobile devices are dropped.
Enterprise servers require SSDs to achieve fast read and write times to properly serve their client PCs.
