1. Synology DiskStation DS220j – Recommended and Affordable NAS for Remote Access

This is the best NAS for remote access as it offers high data availability. This possible because it can run 24/7 with minimal interruptions as long as it is powered and has a stable connection.

The diskless system is popular because it is very affordable. Users getting into personal cloud storage will appreciate the value for money that this system brings, that and the fact that it is also very compact and does not take up too much space.

It is easy to set up. Thanks to Synology DSM (DiskStation Manager), the OS that runs this NAS you get access to a wide range of pre-installed apps that will make configuration much easier and allow you to set up things like remote file backups and media streaming with the help of an integrated media server,

Because it is highly compatible with other computers, you can access the files on this remotely via your Mac, Windows, and Linux machine. You can also view your files through your phone from anywhere in the world as long as you have a decent network connection.

2. Synology DiskStation DS920+ – 4-bay Diskless NAS with NVME slots

This unit comes with 4 drive bays and you can even extend this further by getting the DX517expansion unit from Synology. This will bring the total up to 9 drives. This results in higher storage capacities, making this the best NAS for remote access.

This means you can equip it with high capacity drives, letting you store larger volumes of files that you will be able to access from anywhere in the globe as long as you’re connected to the internet.

Despite being small and compact, you get very good performance capabilities. The NAS ships with 4GB of DDR4 RAM. Over time, if your needs increase, you can upgrade the memory to 8GB for better multitasking.

While the bays are equipped with HDDs, you may need faster disk performance. Instead of getting new 2.5-inch SSDs, you can make use of the two M.2 NVME SSD slots that are already provided.

Equipping these with SSDs will let your system have a high-speed cache for the files and data that are regularly accessed, also known as “hot data“.

3. Synology DiskStation 1819+ – Diskless, Has 8 drive bays

This NAS has 8 drive bays, is diskless, and has support for expansion, meaning you can get more drive bays if needed.

This is a very expensive NAS, and unlike many others, it is suited for demanding workloads. In times where people work from home, this is the best NAS for remote access.

It comes with 4GB of RAM. This is great for moderate workloads and supports a lot of multitasking, but, as the number of users grows, this can be upgraded to a whopping 32GB, with two 16GB units.

Furthermore, the system is built ready for high performance. You get sequential read and write speeds in the tune of 2045 and 656MB/s. This would require the NAS to be plugged into a network that can handle the high-speed connection for remote access.

The NAS itself comes with 4 ethernet ports, and it also has an expansion slot that can be equipped with a 10GbE network card as needed, so on the networking front, you get good support.

There are NVME slots that can be used for caching for faster read and write speeds.

4. WD My Cloud EX2 Ultra – Easy setup, comes with disks

What makes this the best NAS for remote access is the setup process involved. All you need to do is connect it to your router via the provided ethernet port, power it up, and finish the setup process online by signing in to your account.

This is made possible because the NAS is not diskless. It comes with pre-installed drives which eliminate the need for fumbling with the case to open it up and install drives. This also makes it easier for people who are new to NAS to get onboarded quickly.

Other than being easy to use, the NAS has a 1.3GHz processor that runs the OS as well as the apps. It also relies on the1GB of RAM provided which makes appealing for remote access both as a media server and a business tool.

There are various storage options depending on how you configure yours. With larger capacities, you will have adequate space for numerous media files as well as documents, and the lower capacity units are more ideal for people with fewer files and a limited budget.

5. TerraMaster F2-210 – Very affordable dual-bay NAS

This unit comes in at less than $200. That makes it a great entry-level NAS for users who have a limited budget and are looking for the best NAS for remote access.

At the same time, you get a unit that’s built to run efficiently in small offices with just a few personnel and low to moderate network traffic.

That said, the TerraMaster F2-210 does have some good features. It has two drive bays that can be equipped to support RAID configurations. This can come in handy because for remote access, disk failure can result in data availability which can interfere with user experience.

You also get 1GB of RAM. While this is not upgradable, it is suitable for the workload that this NAS is built for and is more than capable of handling user requests without lags.

Read and write speeds are in the tune of 114MB/s. This isn’t very high, and will vary depending on your network. It’s, however, enough to get work done. The NAS can be fitted with SSDs for faster performance.


Finding the Right NAS With Remote Access

best nas for remote access

The main point of having a NAS is to have central storage space for large amounts of files and to have it available without being next to the device.

Remote access on a NAS is essential, especially in situations where people work from different places or are traveling.

Some of the features you would need in a NAS to make it ideal for remote access include the following:

Fast Networking

Having a fast and stable network is great, but if your NAS can’t make use of it then you will be at a disadvantage, especially when reading and writing large volumes of files.

Various NAS systems use different methods to implement fast networking. Many have Gigabit ethernet connectivity which allows fast and stable networking.

Others come with multiple ethernet ports. On some, the ethernet ports support a feature known as link aggregation. This essentially lets you use multiple network ports as a single logical connection, resulting in increased bandwidths.

Some NAS have expansion slots that can have better and faster networking cards installed. With 10Gigabit network cards, users can have SSDs in their NAS and make full use of them remotely. All this, of course, will depend on the remote user’s internet speed.

RAM and Processor

A fast processor will be great for remote NAS access. If many people are connected simultaneously, this will keep the people served well and ensure data is handled efficiently to reduce lags.

Ample RAM will also facilitate this, by playing a pivotal role in the system’s multitasking. A lot of RAM means fewer CPU operations in scheduling memory, and more time is spent on actual beneficial work.

This is why many systems come with upgradeable RAM. This allows you to scale according to personal as well as business needs when it comes to RAM operation and remote file access.


With remote access, there’s a lot of vulnerabilities. Sensitive and private data can be intercepted and land in the wrong hands which can be bad for business. Having a NAS with encryption can help reduce the risk.

By securing your files with a password, you will be able to safely and securely access them over the internet with reduced risk.

With encryption, file sharing becomes more secure as well, as you can determine and control what other users do on the NAS. A NAS that balances security with usability is ideal.

Final Words

Remote Accessing is one of the most critical feature that NAS can have particularly if important work has to be done outside office.

Besides that, remote access can also be very important to home users for accessing their essential data on their central storage.

Here we reviewed some of the best NAS for Remote Access from various size and price category.
