Network Attached Storage (NAS)

Understanding High-Capacity NAS Systems

Network-attached storage or commonly known as NAS devices is a single unit that provides a file-level storage server that is connected to a computer network. This provides data accessibility to a group of varying heterogeneous users. At the basic level, high-capacity NAS is different from other storage systems like SANs in the sense that it provides file-level storage, which means that the users can access in the form of files, instead of blocks which is provided by SAN.

NAS storage systems are best used for fire sharing, collaboration, and backup. NAS for small businesses is especially a good choice because they are quite affordable and easy to use even for novice users.

How NAS Devices Work

Reliable NAS devices are a type of self-contained device, which means that they can contain one or more than one hard drive. In the unit, the hard drives are connected to the motherboard of the NAS system and the device is itself connected to the network.

When a user tries to access the files on the device, they first send a request to the NAS device over the network. After that, it gets the data from the NAS hard drive and sends it back to the user.

Some Key Features of NAS Storage Systems

Data Protection and Redundancy: NAS devices provide very efficient protection against disk failures. They often have built-in RAID arrays to provide redundancy, which is very essential to provide data security.

Scaleability: A great advantage of using NAS devices is that they are very flexible and you can easily attach more hard drives to scale up your system.

Remote Access: Most NAS storage systems have enabled remote access, which means that users can access files from outside the local network.

Things To Consider When Buying NAS Accessories

Buying NAS storage solutions can be a little bit tricky, and you should always keep some factors in mind before purchasing any device.

Performance: The data transfer speed is among the most important factors to consider. Before buying the device check whether the hard drives in the NAS system are HDDs or SSDs, as they heavily impact the overall performance.

Compatibility: make sure the device you choose is compatible with the operating system of your network and other applications

Redundancy: Always choose devices that provide RAID configuration to safeguard your data from disk failures and other problems.
