There are three types of data storage: DAS, NAS, and SAN. DAS (direct attached storage) allows data to be connected to a server, making it easier to set up. NAS (network attached storage) requires a storage device that will be accessed through network shares. This centralization of the data is helpful, but keep in mind that it will require more time when accessing it. SAN (storage area network) requires iSCSI or Fibre Channel to create block level access to the data storage. This is great for companies that need something to expand along with them, while also keeping a centralized storage system. It also has fast access times and more redundancy. As with many tools, it is important to find out what an organization’s needs and resources are before selecting a specific storage type. However, even though DAS and NAS are cheaper and easier to configure, SAN is not. SAN requires a good amount of money and skill to implement. DAS can give fair data protection, but NAS can give a good centralized system (Kirvan et al., 2025).
