Learn about the concept of persistent storage, which refers to data storage systems that can keep data even after turning off the power. This type of storage is also commonly referred to as non-volatile storage. Examples of persistent storage include DVDs, hard drives, and tape.
What is Persistent Storage?
Persistent storage is a term used to describe a data storage system that can retain data even when the power source is switched off. Once data is stored in such storage, it remains there until it is intentionally deleted. This is in contrast to volatile storage that cannot keep data after the power is turned off.
Types of Persistent Storage
Magnetic and optical media types are the common kinds of persistent storage. Hard drives, DVDs, and tape are some examples of magnetic storage. On the other hand, optical storage includes CDs, DVDs, and Blu-ray media.
Is Persistent Storage the Same as Permanent Storage?
The term “permanent storage” is unnecessary since all storage is permanent until it is intentionally deleted. In contrast, persistent storage refers to data storage systems that remain even after power is turned off.
Conclusion
Persistent storage is vital as it ensures that data remains intact and readily available even when there are power outages, system crashes, or other unexpected events. Understanding how persistent storage works can help you choose the right storage options for your needs.
FAQ
- What is meant by persistent storage?
- Persistent storage is a type of data storage system that retains data even when power is turned off.
- What is the difference between volatile and non-volatile storage?
- Volatile storage requires a steady source of power to keep data intact, while non-volatile storage, also called persistent storage, retains data even after power is turned off.
- What are some examples of persistent storage?
- Hard drives, DVDs, tapes, and Blu-rays are some examples of persistent storage.
Choose the right storage options for your needs with a better understanding of persistent storage.
