7 Best Network Attached Storage Devices for Small Business


Data is always the major priority for any establishment. Therefore, adjustment with the same is not acceptable. DAS, SAN and many other proved inefficient for the purpose due to one or the other limitation. 

IT, Business and other technical sections are growing day-by-day. With growing industrialization and Globalisation, the handling of data also increases. For every establishments huge data sharing is included. The secure and reliable storage and sharing of the data is major goal for handling the same. Well, earlier the storage Area Network was used to incorporate data storage and sharing action. Later due to minimum efficiency and resource limitation the Network Attached Storage devices were invented. These were the LAN based technologies that comprised of single network handling multiple server clients at same time.

What is network attached storage devices?

Network Attached storage devices enable user to share files including data over a specific designed network. The data transfer and retrieval process from the centralised network becomes easy and initiate a reliable exchange. Furthermore, the sharing of files from authorised system to another same system is secure enough to maintain the privacy norm in action. In NAS (Network Attached storage) IP address (Internet Protocol) is the routing agent that delivers the address of transfer in the network.

The integral advantage of the NAS system is that, it eliminates the need of several servers at distinct location to connect the clients to the established network. The major difference between SAN (Storage Area Network) and NAS (Network attached storage) is the type of data level access they peruse. SAN and NAS initiate block level data access (and Sharing) and file level data access (and sharing) respectively.

In Direct Attached Storage each server/client was directly connected to the centralised system. Therefore, the resources were segregated among all the data servers that was not feasible enough. The time of transfer and the resource utilisation was not adequate to the expectation of reliable data orientation. As a result, in NAS the system equipped a network (Mostly Local Area network) based on TCP/IP Protocol that reduces the issue related to resources, speed, storage, security and reliability.

Features of a reliable NAS are as follows:

  • File Level Data Access
  • Proper resource availability
  • Higher Performance and speed of sharing
  • Centralised network-based storage system
  • Single Purpose file storage and sharing system
  • And Many more.

Buying Guide

  1. Form Factor: Rack mount and tower type are the two methods of available hardware for NAS Device. Form factor defines the size shape and aesthetic feel of the system to handle and place at the workplace. According to the storage available consider the rack mount or tower placed NAS device suitable for the user.
  1. Ease of Use: A highly complex NAS system requires always a professional to handle the system and further maintain it. An easily understood and user-friendly device would be more efficient to use by the executives and experience the more-better advantages of network attached storage technology.
  2. Reliability: It is the measure of value of retaining the loosed data during the down time or emergency issues. The NAS device should be reliable enough to retrieve data after some malfunction or other unexpectable scenario occurs.
  1. Security:  The NAS device in purchase should have a transcoding encryption and decryption algorithm inbuilt to avoid the virus and loss (Access) of data to the third party.
  2. Power requirement: The efficient NAS device should be power efficient had comprise of the alternatives to the power needs with emergency shut-off and other such activities. It should co-relate with the existing PC (operating system) connected with the same.
  3. Connectivity and Configuration: The protocols like CIFS, FA and SSCI should be incorporated in the configuration layout of NAS device. The TCP/IP connection algorithm with CIFS and FA based on terminology should be accepted.

Things to consider before buying Network attached storage devices:

There are wide range of NAS devices available in the market. Each comprise of distinct specification and includes variable range too. Well, for the users familiar with the system can easily identify their need for data storage and sharing and choose the relevant device for the same. But for the one who are beginner with the technology should keep in mind few points before purchasing the best as per the requirement.

Study the specifications of NAS device:

The basic components of NAS system includes:

  • NAS CPU (Memory)
  • CIFS and NFS Protocol (Required for file sharing)
  • Operating System
  • Network Interface Cards (NICs) for example: Ethernet and FDDI
  • Storage Protocol like ATA, FC etc.

Review the above components in the NAS devices before buying them.

Random Access Memory (RAM):

RAM is responsible for the speed and the sharing of data relevancy. Though the parameter is common in PCs and NAS device but plays an integral role in the speed of accessing and sharing the files over the network. Therefore, it is mandatory to check this parameter. Higher RAM is always appreciated for NAS device to ensure the speed of exchange.

Bay Count (Disk Capacity): 

Bay Count determines the number of Disk Drives accumulated in NAS device. More the Bay counts more the storage availability and more efficient the network transactions.

Processing Power:

NAS are the part of the network. Unlike any personal computers NAS are just a component therefore, there is no need of establishing a different power source for the same. The processing and power features behave well and good with the attached desktop or any other operating system.


Study the specification, requirement and recovery period of the NAS system. It should have a in-built programmed feature to recover the data at times of failure.


  1. Which NAS drives are more useful, Populated or Diskless?

Answer: Well, many manufacturers of NAS devices are manufacturers of drives too. So, in many brands those people suggest an inclination to populated NAS devices. While other go for Diskless. If a NAS system is available in both populated and diskless check out the costing of the device. If there’s not a much difference and you can afford the same get the pre-populated. As these are more reliable enough considering the storages. (if cost difference is high get diskless).

  1. Will NAS solve my huge data storing purpose?

Answer: Yes, NAS is entirely based on storage and sharing of Data over a Reliable network.


Network Attached Storage has made the easy, reliable and efficient way of storage and sharing of data. The TCP/IP based NAS devices (Systems) are well equipped with resource handling activity procedure and provides a quick way to access the connected server client system. It is crucial to research the requirement for our NAS specification before buying the device. The parameters and specification especially the Disk count (Storage capacity), operating system, operating frequency, Range, reliability and security should be analysed in a planned manner.

NAS devices are a good option to replace the individual complex connection. It is thus a convenient way to implement on our workplace. If the needs are analyzed properly, definitely one of the above mentioned NAS devices will count in your buying list.
