Network-Attached Storage (NAS)
NAS devices offer Redundancy using RAID technology in case of hard drive failures. This simply means that you can use multiple hard drives to backup your data and if one fails, there is another one available to take over your backups.
NAS System provides remote access which means that you can access your files anytime and anywhere.
With a NAS system, you will get more value for your money with this all-in-one backup and storage solution for your business.
Storage Area Network (SAN)
SAN allows you to pool your storage and dynamically allocate exactly what each server requires. This means you'll spend less on drive for your servers and use the space on your SAN more efficiently.
There's a limit to how many drive your servers can accommodate. There's also a limit to how many hours you have to spend managing storage space on those servers. A SAN has limits, too, but they're much more scalable.
SANs are incredibly resilient and ensure you data is secure and available even in the event of all but the most serious hardware failures.
Deploying a unified storage system takes away the guesswork associated with planning for file and block storage capacity separately.
Unified storage gives users a choice regarding how they store virtual machine (VM) data without having to separately buy SAN and NAS capacity.
Users can allocate storage to support application requirements regardless of whether the application requires block or file data access..
