Tertiary storage media is a type of data storage device that is used to store large amounts of data that are not frequently accessed. It is typically used for archival purposes, where the data needs to be stored for a long time and accessed only occasionally. Tertiary storage media is often used in combination with other storage media, such as disk and tape, to provide a comprehensive storage solution.
Tertiary storage media devices include optical disks, such as CDs, DVDs, and Blu-ray disks, and magnetic disks, such as magneto-optical disks. These devices offer large storage capacities, ranging from a few hundred gigabytes to several terabytes, and provide high durability and long-term data retention. They also offer faster access times than tape-based storage systems, making them suitable for applications where fast access to data is important.
One of the main advantages of tertiary storage media is its cost-effectiveness. Tertiary storage devices are often less expensive than other types of storage media, such as hard disks or solid-state drives, and can be used to store large amounts of data at a low cost. This makes them ideal for long-term archival storage and backup purposes.
However, there are also some disadvantages to using tertiary storage media. One of the main drawbacks is the slow access times compared to other storage media, such as disk or tape. This makes it unsuitable for applications where fast data access is critical, such as online transaction processing systems. Another disadvantage is the limited write-erase cycles of some devices, such as optical disks, which may limit their useful lifespan.
In summary, tertiary storage media is an important component of a comprehensive data storage solution, offering large storage capacities at a low cost. While it may not be suitable for applications that require fast data access, it is an ideal solution for archival storage and backup purposes.
