The 5 Best NAS for Macs: Backing Up Your Mac

Key Points

  • An NAS is similar to a public cloud service like Google Drive or Dropbox, but for Mac users–it lets you access your files and keep complete control of your data.
  • With a competitive 1.3GHz processor and 1GB of RAM, the Western Digital 8TB My Cloud EX2 Ultra is an affordable NAS system, preconfigured with 8TB of storage across two drive bays.
  • Most NAS systems offer some sort of encryption. Look for an NAS with a closed operating system. This will ensure that 3rd party and unsigned applications can’t run on your NAS.

What is the best NAS for Macs? If you care about the safety and security of your data, backing up your files should be a priority. A network-attached storage device, or “NAS” for short, is the perfect solution. A NAS allows you to access your files from your Mac or any device similar to a public cloud service like Google Drive or DropBox. Unlike a public cloud, a NAS lets you keep complete control of your data.

There are several options available for backing up your Mac. You may be familiar with USB flash drives, external hard drives, and even DVDs. These are commonly used to back up data but have some limitations. With physical storage devices like this, you need access to the device to use it. Additionally, you need to be careful to avoid wear and tear.

Cloud storage services like Google Drive and DropBox exist as an alternative to direct-attached storage devices like flash drives. With cloud services, you can access your data from any device, whether your Mac or your iPhone. Apple even offers iCloud as its own cloud service for Apple devices. The main drawback to cloud services like these is that you are not in complete control of your data.

A NAS is often the perfect solution for companies that require a private cloud to store sensitive information. Even if you just want a NAS for home use, the benefits can make it worth it. Depending on your configuration, you can access your NAS from any device in the world through the internet.

How To Pick The Best NAS For Macs: Step-by-Step

If you are just being introduced to the world of network-attached storage, the choices can be intimidating. You’ll be able to figure out the best NAS for your situation if you keep a few key areas in mind:

  • Capacity
  • Performance
  • Connectivity
  • Security
  • Reliability

Let’s review each one in more detail.


Capacity is a priority in any storage device. NAS systems are capable of holding dozens of terabytes of files. The capacity of a NAS is determined by the number of hard drive bays it has and the capacity of the hard drives. Some NAS systems are sold in a diskless configuration, meaning it is up to the user to install their own hard drives.

RAID is also something to keep in mind when determining the capacity of your NAS. Different RAID configurations will leave you with different amounts of usable space. For instance, an 8TB NAS running in RAID 5 will provide you with 6TB of usable space. However, RAID offers you several advantages, including data redundancy and higher performance.


In general, NAS systems are used for storing and accessing files. The system still requires a powerful processor for efficient operation. Furthermore, having more people connected to the network requires speed. Just like regular computers, NAS devices measure performance based on processor type, core count, and speed.

A typical NAS will have a less powerful CPU than a desktop computer, but the specialized operating system makes more efficient use of the hardware. As a result, a super powerful processor is not necessary – a dual-core, low-clock speed processor is just fine.


Not all NAS systems offer the same connections. The one thing all NAS units have in common is ethernet. Some systems will also offer WiFi or USB connections. Determining the connections you need will help you narrow down the best NAS for you. A USB connection can come in handy if want to make a direct connection to your NAS. 

Premium NAS units will offer multiple ethernet ports for even higher bandwidth. The most basic requirement for connectivity is at least one gigabit ethernet port. This will allow you to connect the device to your network and enjoy all of the advantages of a NAS.


Secure network-attached storage is essential for protecting sensitive data from unauthorized access. Most NAS systems available today offer some sort of encryption. Ideally, you should select a NAS with a closed operating system. This will ensure that 3rd party and unsigned applications can’t run on your NAS. As long as you have a closed system with built-in encryption, you won’t have to worry about the security of your files.


Reliability is one of the most important factors when choosing a NAS. Most systems will include a warranty of some sort, but a longer warranty is obviously superior. Additionally, a system with built-in RAID functionality or data duplication will ensure that you are more protected against data loss.

What To Know Before Buying a NAS for Mac

Before settling on the perfect NAS, you should know which type of NAS is right for you. Do you want a preconfigured NAS that’s easy to set up? Or do you want to buy a diskless system? A diskless NAS will require you to research, purchase, and install your own hard drives. On the other hand, a preconfigured NAS may be simple but could limit your upgrade options down the line.

Either way, knowing how to set up your NAS is paramount. Luckily, even high-performance NAS systems are easy to set up, and almost every NAS on the market is compatible with Mac OS. Most systems even include a mobile app for installation, so you don’t even need to involve your computer. If you run into problems, most NAS providers offer technical support as well.

Using a NAS for Mac: What it’s Like

Your experience using different NAS systems will vary depending on your configuration. In our experience, the best NAS is easy to set up and easy to use daily. More complex systems may offer performance advantages but at the cost of ease of use.

A pre-configured NAS offers the best user experience. You don’t need to worry about installing your own hard drives by ordering a pre-configured NAS. Additionally, an easy network setup process makes a NAS more enjoyable to use. In our experience, the best NAS systems offer a free mobile app or downloadable program for installation.

The end result should be a NAS that is always available wherever you are. Simply load up your NAS from your computer’s file directory and back up your files on an as-needed basis. Additionally, some NAS systems provide automated backup software, so your critical system files are always backed up.
