Storage capacity definition
Storage capacity represents the digital data a device or system can store, handle, or process. It varies depending on the type of device or medium, such as hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, memory cards, and cloud storage services. Devices with higher storage capacities can usually store more data, making them more versatile for different applications. However, storage capacities are often a target for hackers who try to steal user data.
Storage capacity types
- Primary storage. It stores data currently processed by the CPU. Usually, volatile memory devices such as RAM (random access memory) and cache memory provide primary storage.
- Secondary storage. It stores data not immediately required for processing but needs to be retained for later use. Non-volatile storage devices, such as hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, and memory cards, usually provide secondary storage.
- Tertiary storage. It serves for long-term backup and archival purposes and includes technologies such as tape drives and optical discs.
- Networked storage. It enables centralized storage and easy sharing of data across multiple devices. Network-attached storage (NAS) devices provide it as a service.
- Cloud storage. It enables remote storage and retrieval of data over the internet. Users often utilize it for backup and collaboration purposes. Popular providers include Dropbox, Google Drive, and Amazon S3.
Protecting storage capacity
- Regularly update your software and apply advanced security measures, such as TLS, server message block, and SSL encryption.
- Employ control access systems to provide minimum access to the data storage and avoid sharing passwords with more people.
- Utilize data encryption and implement encryption key management.
- Monitor the storage capacity to detect suspicious behavior and unusual data access patterns.
