In the world of data storage, storage devices are divided into one of two categories based on how frequently an organization needs to access that data: primary storage and secondary storage. In this article, we’ll take a closer look at these two categories as well as clear up some ...
Secondary data storage, on the other hand, offers long-term storage, like a person’s long-term memory. Secondary storage tends to operate with less frequency and can require more computer processing power to retrieve long-stored data. In this way, it mirrors the same retention and processing ...
Secondary Storage: Your Long-Term Data Repository Per TechTarget,“secondary storage is persistent storage for noncritical data that doesn't need to be accessed as frequently as data in primary storage, or that doesn't have the same performance or availability requirements.” While primary storage...

mainframe computers ruled the data center, the term primary storage often referred to the volatile memory in the computer -- much like RAM in modern servers -- rather than the media that provided a permanent, persistent home for the data that might have been called secondary storage at that ...
Data is stored on a primary storage system and a copy of the data is stored on a secondary storage system. A determination is made that a connection between the systems is currently unavailable. Location data is maintained that identifies where changes have been made to the primary storage ...
Primary storagecomprises system memories, caches, and CPU register sets. • Secondary storage is the first level that leverages mass-storage devices. Normally, CPUs cannot directly access the secondary (or higher-level) storage and therefore transfers of data between the primary and secondary storage...
In the world of backup, these terms are used to define the two kinds of storage you should include in your backup plan. At their simplest, primary storage is defined as the storage used to host your critical systems and their data, while secondary storage is the storage that hosts all ...
