SAN Storage vs Traditional Storage on Server Disks

SAN Storage has grown into a preferred option for storing large amounts of data. They offer several benefits when compared to traditional server disks.

Cost factor

SAN storage is expensive in comparison with traditional server disks, but they are long-lasting and efficient, thus saving you a good amount of money in the long run. The underlying hardware in SAN storage makes them way more reliable than traditional server disks and “single points of failure” are rare. On the other hand, traditional storage models record frequent failures due to the use of commodity hardware.


Apart from cost savings, SAN storage systems provide agility too. They can perform operations faster, making them respond rapidly and effectively to evolving business conditions or requirements. Agility is a bigger advantage than cost savings as the deployment of traditional models can take a few weeks after the purchase decision is made until the point it is ready for use, but SAN storage takes hardly a minute to install. Automation is also a component of SAN storage and their agility to automate some of the operations are much easier to integrate and use.


The availability of traditional storage models is based on their custom hardware’s reliability. The reliability of SAN storage disks, on the other hand, comes from the software. Since hardware is likely to fail in environments that are highly scalable, the software’s job is to ensure that things work continuously in self-healing and intelligent processes. The distinction in concept enhances the reliability of SAN storage models and makes them highly reliable in comparison with traditional models.


Since the scalability of traditional storage models is limited, they generally serve only one purpose and usually only a single or a limited number of administrators. They are also prone to performance problems due to improper separation among workloads. As a result, they will make users incur costs since unused space from one storage disk cannot be utilised by another disk. Storage administrators also find traditional models inefficient, but SAN storage models are designed with multi-tenancy in mind. They can easily and effectively separate workloads, thus allowing you to swiftly reallocate unused storage to other tenants or applications.
