Andmesalvestussüsteemid, or data storage systems, are technologies and methods used to store, manage, and retrieve digital data. These systems are essential for various applications, including databases, cloud storage, and backup solutions. They can be categorized into several types based on their storage medium and access methods.

Hard disk drives (HDDs) and solid-state drives (SSDs) are common types of data storage systems used in personal computers and servers. HDDs use spinning disks to read and write data, while SSDs use flash memory, offering faster access times and greater durability. Network-attached storage (NAS) devices provide centralized data storage and sharing over a network, often used in home and small business environments. Cloud storage systems, such as Amazon S3 and Google Drive, store data on remote servers accessed via the internet, offering scalability and accessibility.

Data storage systems also include databases, which are organized collections of data designed for efficient storage, retrieval, and management. Relational databases use tables and relationships to store data, while NoSQL databases offer more flexible data models. Backup systems ensure data integrity and availability by creating copies of data that can be restored in case of data loss or corruption.

The choice of data storage system depends on factors such as data volume, access speed, durability, and cost. Organizations and individuals select the most suitable system based on their specific needs and requirements. Advances in technology continue to improve data storage systems, offering greater capacity, faster speeds, and enhanced security features.
