What is Cloud Storage – NAS vs. SAN

When it comes to your business, no detail can be overlooked. Storage in the cloud is no exception. In my last post, What is Cloud Storage?, I wrote about cloud storage in general. Here I want to go through the two main options for cloud storage, NAS (Network Attached Storage) and SAN (Storage Area Network).

What is Cloud Storage – NAS?

NAS is generally used for file-level computer data storage but NAS provides both storage and a file system. In fact, NAS is useful for more than just general centralized storage provided to client computers in environments with large amounts of data. By providing storage services, NAS can enable simpler and lower cost systems such as load-balancing and fault-tolerant email and web server systems.

What is Cloud Storage – SAN?

SAN is a dedicated network that provides access to consolidated, block level data storage. Common uses of a SAN include databases, server clustering, messaging applications (e.g. Microsoft Exchange), and high I/O, transaction-intensive apps.


NAS provides both storage and a file system, whereas SAN only provides block-based storage and leaves file system concerns on the “client” side. Also, SAN commonly utilizes Fibre Channel interconnects while NAS typically makes Ethernet and TCP/IP connections.

HOSTING uses these leading storage technologies and a fully redundant architecture. Whether it’s dedicated servers, on-demand cloud services, or disaster recovery solutions, we will customize a managed storage configuration to ensure business continuity in the event of a system failure.

See the chart below for more information on the difference between NAS and SAN.
