Network-attached storage is a centralized storage server that allows multiple users and heterogeneous clients to access data from the device and share that data within a local network. NAS functions like a local cloud storage. A NAS device is very similar to a computer that is dedicated to storing, archiving, retrieving and connecting all your other personal computers.

Most of us have lost data at one point in our lives, and we all know that it hurts a lot. Losing years worth of personal files such as family pictures and videos can leave you feeling disoriented. 

Fortunately, there are ways of minimizing the risk of losing vital data – one of those ways is by acquiring a reliable network-attached storage device for your home.

A NAS allows you to store data on the device and share the data within a local network. Network-Attached Storage devices have more to offer than storage and sharing functions. Modern NAS devices are equipped with processors and RAM which facilitate in speedy access and transfer of files. A NAS can be more cost-effective than paying recurring amounts for a cloud drive. NAS is an excellent investment for the storage and security of your data.

The wide variety of Network-attached Storage devices in the market can have you feeling confused and unsure of which one to purchase. You, however, don’t need to worry anymore, because this post will serve as a comprehensive guide on buying NAS devices.

What are the factors to consider when shopping for a Network-attached Storage/NAS

  • Diskless drives - most network-attached storage devices are sold diskless. It is therefore important to factor in that you will need to purchase hard drives separately.
  • Type of processor – this determines the processing power of the NAS. Just like personal computers, NAS devices are installed with a CPU. NAS CPUs are similar to PC processors, except for differences in processing power. Since NAS devices are dedicated to storage and data sharing, they do not need extremely powerful processors for them to perform effectively.
  • Random access memory – again, just like PCs, NAS have RAM. Random access memory determines the speeds at which data is accessed in the disk drives. More RAM would be better for your NAS.
  • Bay count –bay count refers to the number of disk drives a NAS device can accommodate. The total storage capacity of a NAS depends on the number of bays and the capacity of each hard drive.
  • Redundant Arrays - redundant arrays work as backups in case the NAS malfunctions in one way or the other. Redundant discs can protect the data stored on your device and enhance system speeds.

Final Thoughts

Network-attached Storage devices can be a good investment if approached wisely. These devices provide safety and security for your data, and they are reasonably affordable.

Every family or business is faced with different data needs. This makes it impossible to single out one great NAS for everyone. Eventually, you have to make the ultimate choice based on your needs and preferences.

The main features of the NAS device should be thoroughly looked into because the performance of your device depends on this. Perhaps the two most important features to look at are processor and storage capacity. You, of course, want a processor that is powerful enough to serve your data needs.A slow processor can cause delays while sharing and retrieving data. It can make the entire network slow.

It is also crucial that you carefully consider your data needs before buying a NAS, as this will enable you to make a better decision. We hope that this guide will help you acquire the most suitable Network-attached device for your home use.
