The choice of whether to implement SAN or NAS should depend on the performance you want and its ease of use. NAS is file-based storage that’s less expensive and easier for organizations to work with. SAN is block-based storage that’s more expensive but provides better performance.
A NAS system provides a single storage device that is directly attached to a LAN and offers shared storage to all clients on that network. A NAS device is simple to install, easy to administer and low-cost compared to a SAN. However, it provides limited throughput for incoming data because it has only one network connection, and this can become problematic in high-performance environments such as surveillance applications. For smaller businesses that use fewer cameras, this is of course not an issue. The ease of installation and management of NAS boxes is also an attractive feature for smaller businesses which may have lower IT budgets and fewer staff dedicated to IT support.
Some of the pros and cons are given below:
NAS Pros : Consolidated security,Simplified architecture,Inexpensive,Specialization etc.
NAS Cons : Limited scalability,Minimal speed,Network dependent etc.
SAN Pros : High performance,Fast backup,Disaster recovery,Better redundancy etc.
SAN Cons : High complexity,Upfront cost etc.
NASs are reliable, inexpensive, and ideal for SMBs looking for an easily implemented storage solution.
SANs are high-performing, complex systems and ideal for mission-critical tools and companies looking for top-of-the-line storage performance and reliability.
Selecting the right approach to data storage in a surveillance environment will differ from organisation to organisation: as in many environments where performance can be a top priority it makes sense to start the search for a solution by looking to address the essential requirements, rather than listing cost at the start. When it comes choosing the right storage technology for a surveillance environment, there are pros and cons to both SAN and NAS. The right fit for your business is out there and ready to help you improve your IT budget’s return.I would recommend SAN technology for your small requirement due to its high performance and higher reliability.
