How to Choose the Best NAS

Why You May Need NAS And How It Can Be Used

Why get a NAS when you can just use an external hard drive to store your data? A NAS connects to a network, not a computer; this means that you have much more options for what you can do with the stored data. If something happens to your computer, you might lose that data forever. With NAS, your data is still safe within the connected network. Additionally, you can also use NAS to stream content, such as music and videos, anywhere you go.

Here are a few reasons why you might need NAS at your home or office:

• Everyone using the network can access the data
• Passwords can be set up for certain devices to keep things private, while still storing the data in a safe place
• NAS has its own operating system, so you don’t have to rely on a monthly subscription service to store your data; you have full control and you only have to make one purchase
• NAS is scalable, meaning that you can add more storage options, such as hard drives and additional NAS units, as your needs change over time
• Depending on the configurations, NAS is versatile and can come with several additional features, such as the ability to download large amounts of internet data even during travel
• NAS units are usually more reliable than other storage options because they are built to run at lower temperatures with a specific focus on data storage

Understanding NAS units and their specifications can be a challenge. If you’re thinking about getting the best NAS for your needs, it’s important to research how to setup your NAS in the way that works best for you.

NAS Capacity

A NAS holds hard drives within it. These hard drives can have different storage capacities.

Depending on the size of your family, business or data usage, the size of NAS you need will vary. Here are some things to consider when choosing a NAS based on capacity:

• Documents: Word documents typically don’t take up much space, so if you may not need to spend more on a larger capacity NAS if you’re just storing these types of files, such as in an office.
• Media (music, movies and images): If you’re an avid media user, editor or photographer, you’re going to need lots of space to store those files. The higher quality media you use (such as HD videos), the more storage you’ll need. This is especially true if you live or work in a place where multiple users are accessing and sharing very large data files.
• Do you use RAID? RAID (“Redundant Array of Inexpensive Disks”) is something that you enable in a system, such as a NAS unit, that provides fault tolerance and performance optimization. Essentially, RAID provides added protection for your data and helps your NAS run as best as it can. If you use RAID, it will take up more space within the NAS, so keep this in mind when looking at capacity.

Disks or No Disks?

Some NAS come with hard drive disks, while others do not.

• The Pros of No Disks: You have the freedom to add your own hard drives based on the size and brand that you prefer.
• The Cons of No Disks: You’ll need to buy extra hard drives and spend more time setting the NAS up.
• The Pros of Disks: A NAS with preinstalled disks is convenient because those disks are already configured for that NAS drive. You can set up your NAS quickly and easily (in comparison to diskless).
• The Cons of Disks: The disk that the NAS comes with may not be best quality based on your needs for space and features.

Connectivity

NAS connects through the network at your home or office via a Wi-Fi network or your router. Most NAS units typically connect using a Gigabit Ethernet cable. In order to get the most out of your NAS, it’s important to have a high-quality router and a strong internet connection.

Remote Access

Whether you own your own business or live in a household with various devices, you might come into a situation where multiple users need to access a large chunk of data. That’s exactly what a NAS does; it makes it so that everybody can store and access data through the NAS server, without worrying about losing or misplacing files.

NAS can give you remote access so that you can view and manage your files wherever you are on whichever device you choose. This can be achieved by making an account with the NAS manufacturer and using your login to access your files.

Security

As previously mentioned, RAID means “Redundant Array of Inexpensive Disks” and it’s designed to provide a safety net for the data on your NAS unit. There are different types of RAIDS. The type of RAID you need will depend on the drive capacity of your NAS unit. Hard drives can break down, and that is why NAS has fault tolerance so that you can save your data even if you lose a hard drive.
