How To Pick The Best Motherboard for NAS: Step by Step

Building your own NAS comes with a unique set of requirements. Typically, you’ll want to connect multiple hard drives to provide your system with as much storage as possible. Additionally, network connectivity is equally important when building a NAS. Keep these four things uppermost in your mind when shopping for the best motherboard for NAS.

  • SATA connections
  • Networking
  • Expansion
  • Price.

SATA Connections

Want to connect a standard desktop hard drive? You’ll need a SATA port. The more SATA ports you have, the more drives you can connect. Since each hard drive will occupy one SATA port, you’ll need to consider how many drives you plan to connect.

A good motherboard should have at least six SATA ports. Some of the best will have up to ten. The speed of the SATA interface is also important. The “gigabytes per second” is critical in determining how fast your data transfer speeds will be. Older standards will run at 3GBps, while newer motherboards will offer a 6GBps connection. 


Another crucial aspect of any good NAS motherboard is enhanced networking features. Ideally, the model you buy should have at least a one-gigabit ethernet port. This will allow you to connect your system to your network and enjoy high transfer speeds.

While you can always add additional network cards later, having a fast ethernet connection built into your motherboard is helpful. Another handy addition is WiFi. If you plan to configure your NAS wirelessly, built-in WiFi is essential.


The last thing you want is a motherboard that will hold you back. A good motherboard will include essential features like good networking and SATA connections and the ability to add more features as you see fit. Expandability is the keyword here. Ensure you buy an expandable motherboard to continue upgrading your NAS for years.

Some key expansion features to look out for include plenty of RAM slots. Having multiple RAM slots will allow you to increase the performance of your NAS with more RAM. Additionally, PCI-E slots are helpful if you want to add more networking cards, USB cards, or even graphics cards.


If you’re building a NAS on a budget, price is something you can’t overlook. Building a DIY NAS is cheaper than buying a prebuilt NAS. If you are wise in your choice of components, you can save money and still build a highly functional NAS.

When shopping around, avoid buying lower-quality components to save money. You may end up replacing cheap parts soon. It is better to buy premium components as they typically last longer and provide years of service.

What To Know Before Buying a Motherboard for NAS

Before you decide on the perfect motherboard for your NAS, you should know the form factor and size of the motherboard you want. If you already have a PC case, this is easy. Just look at what form factors are compatible with your case. Mini-ITX, ITX, Micro-ATX, ATX, and EATX form factors are motherboard options. Each type has its pros and cons, but the main differentiator is the size.

Additionally, you should ensure the power supply requirements for your motherboard and the rest of your build. You don’t want to buy a power supply incapable of handling the power needs of the components in your NAS. Typically, a NAS will house many hard drives and may use much more power than a standard computer, so ensure the power supply is adequate.

Another thing, decide on what processor to use with your motherboard. While the processor is not important for NAS, you don’t want to buy an Intel motherboard if you have an AMD CPU, and vice versa. To be sure your processor and motherboard are compatible, look at the socket type for the motherboard, and make sure it matches the socket type required by the processor.

Using a Motherboard for NAS: What It’s Like

While a prebuilt NAS will save you the hassle of picking out a motherboard, building your own NAS offers numerous advantages. For example, you can customize your NAS to an incredible extent and pick out all your components. 

So how should you go about the process of using your new motherboard? The first step is ensuring you have all the necessary components, from the RAM, power supply, CPU, and hard drives. Once everything is together, you can begin your DIY NAS build.

Install your CPU and motherboard in your PC case of choice, and configure your operating system. FreeNAS is a Linux distro designed for DIY NAS builds, but any version of Ubuntu or Windows will also work well.

Having a motherboard with easily accessible SATA ports makes it easy to install new hard drives and add more storage to your NAS. If you want to add more components over time, you’ll be glad you picked out an expandable and powerful motherboard.
