AMD processors are generally cheaper than their Intel counterparts. Therefore, if you want to make a budget compact build with AMD components then you may want to look into this.

This motherboard is NOT extraordinary for NAS, but for a COMPACT AMD build, you don’t have much of an option.

This is a mini-ITX motherboard with 4 SATA ports. Unfortunately, AMD based mini-ITX board cap out at 4 SATA ports. Until that changes in the future, a board like this can come in handy.

This motherboard has an AM4 socket with support for AMD Ryzen and Athlon processors. Along with that, it also has a WiFi that may come in handy when building NAS that can be accessed wirelessly.

It should also be noted that being one of the latest motherboards, it offers the latest Bluetooth V5.0 as well.

All in all, if you are hell bent on building a COMPACT system with AMD components, then this is the best motherboard for NAS.

4. ASRock X570M Pro4 – AMD – Micro ATX – 8 SATA Ports

An affordable Micro ATX motherboard with a AMD 4 socket and 8 SATA ports.

If you don’t mind a somewhat larger Micro ATX form factor, then you will find this to be of an excellent value.

Micro ATX motherboards have a size of 9.6 x 9.6 inches as compared to the 6.7 x 6.7 inches size of the mini ITX we saw above.

Therefore, you will require a somewhat larger chasis, however, you also get a lot more added functionality with a larger form factor.

For starters this is an AM4 based motherboard for the latest AMD Ryzen and Athlon processors. AMD processors generally are quite popular for affordable DIY builds since they are cheaper.

On top of that, it has 8 SATA ports. This is quite the significant number for building a decent sized NAS. You can add 8 hard drives to this board.

Being a larger motherboard, also gives it significantly more capability as compared to a mini-ITX motherboard. It has 4 RAM slots and thsu can support upto 128 GB of DDR 4 RAM.

Furthermore, it supports both ECC as well as the common non-ECC RAMs. However, to use ECC RAM, you will need to get your hands on the expensive Pro series CPU which would not be ideal if you are making a budget build. In that case, you can stick with the regular non-ECC RAM.

Another thing to note is that unlike mini-ITX boards above, this has 2 x PCIe X16 slots with a configuration of X16 and X4 – the second slot works at X4 bandwidth.

This is quite significant if you plan to expand as you would be able to experiment with RAID controllers, add-in-cards etc to customize your NAS even further.

One very significant, and often overlooked, feature here is its amazing phase power design. A phase power design genrally entails the amount of  Voltage Regulator Modules (VRM) used by a motherboard.

The higher the number, the more stable is voltage passing through the board and thus the less prone it is to damage or malfunctions.

It is essential for NAS to remain stable 24/7. A good phase design ensures that. This motherobard has a 10 Power Phase Design.

All in all, if you are okay with a somewhat larger form factor, then this is the best motherboard for NAS with its 8 SATA ports.

A server grade ATX motherboard with Intel C246 chipset, LGA 1151 socket ad 10 SATA ports.

This is the largest motherboardi in this list with an ATX form factor and the highest price tag. However, to be fair, it is still quite reasonable in terms of price if you compare it with ASRock RACK C236 WSI above.

Despite offering so much, it is still quite reasonably priced. Of course, the downside here is that you will need a large chassis as well as a large area for your NAS storage.

The motheroboard has a whopping 10 SATA ports. You can 10 hard drives to this to make the ultimate DIY NAS for yourself.

Being a server grade motherboard it supports both Intel Xeon processors as well as ECC RAM and Non-ECC RAM.

However, if you want to build a budget setup it is equally capable since the LGA 1151 socket here can support processors all the way from Intel Core i9 to Celeron from 8th and 9th generation.

If you are serious about expanding your motherboard with some SATA PCIe Card to add even more Hard Drives to your NAS, you can do so with the plethora of expansion slots its offers.

It offers one PCIE X16 slot running at X16 bandwidth, one PCIE X16 slot running at X8 bandwidth and 2 PCIe X16 slots running at X4 each.

Hence the expandability you can perform here is huge.

For the ultimate DIY option, we recommend this to be the best motherboard for NAS. However, since it is expensive, it may not be suitable for average setup that most DIY builders aim for.

What are People Looking For?

While the beauty of a DIY setup lies in the fact that you can make your ideas come true, there are still a few pointer that can get you started if you are new into building NAS.

Higher SATA Counts

Best Motherboards for NAS
SATA Ports connect harddisk so the more you have the merrier.

It goes without saying that SATA ports are single handidly the most important ports for NAS. The more the number of SATA ports you have, the more hard drives you can fit into the motherboard.

Therefore, you can follow this notion as a rule of thumb that the higher the number the better.

In this article, we have actively listed motherboards that tend to feature the most SATA ports for their price or size category.

Mini ITX Form Factor

What is motherboard form factor
Mini-ITX are recommended for NAS

Many love the idea of their NAS builds to be as compact as possible. That is where the form factors matter.

A smaller form factor of a motherboard would mean that you can fit it into a small chassis.

The smallest form factor available for consumer grade use is the mini ITX. It has a dimension of 6.7 inches x 6.7 inches.

Therefore, the holy grail is to find a Mini ITX form factor with the highest possible SATA ports.

Balance between SATA Counts and Price

Of course the number of SATA ports is not the only main consideration. You have to balance the cost of the overall build as well.

For example certain high end motherboards do feature upto 13 SATA ports. However, such motherboards are not just expensive themselves, but the processor they require is also significantly expensive.

As such, here it would be illogical to invest in such a premium setup as you would otherwise practically be able to build multiple smaller NAS storages for the price of a single setup with the premium motherboard and processor.

Not Processor Hungry

A NAS setup is NOT really a processor hungry setup. However, in the end, it does depend upon what you want to accomplish. If you plan to use the setup as workstation or perhaps build working VRMs, then a faster processor may be best.

However, if you are going to use the NAS as a static storage space, then budget processors would do just fine. Many users are okay with suggesting low key processor i.e Pentium, Core i3 etc as ideal for most NAS.

Final Words

Here we looked at some of the best motherboards for NAS in our opinion while taking into consideration the most common pointers for a DIY setup.

Ofcourse, your NAS setup does not have to be expensive. It just depends upon what you want to accomplish on it. For basic NAS, any budget motherboard with an entry level processor would do just fine.
