While we do strongly recommend cloud storage as one leg in a 3-2-1 backup strategy, a network-attached storage device (or NAS for short) can be even more invaluable for home and small office use.
If you work for a large company, you undoubtedly have remote access to a corporate file server. But if you are employed by a small business or you're working from home, your file server is likely to be in the cloud powered by the likes of Dropbox, AWS, Google, or Microsoft. And while cloud-based servers are great -- and can save your neck more than once -- cloud services may not always cut it for some folks, especially fully remote workers. Similarly, video editing is a much slower upload and download process on a cloud-based server.
So, if you're doing anything with video (or other large files), you're unlikely to find cloud storage practical except for backups. And they can become expensive. Sure, if you're equipping a NAS, you're paying for drives, but once you pay out the expense for the NAS and drives, you're done. You don't have to pay for it month after month, and these smaller, frequent costs over time can quickly add up to more than an initial investment in a sturdy NAS setup.
Also: How to set up your own NAS for more reliable data backups
A NAS is fast, easy to access, and allows you to segment shares for family members or workgroups. Additionally, many NAS devices offer various applications that turn your box into a local, private, on-premises general-purpose business server. Based on extensive and regular testing, research, and expert opinion, 's top pick for the best NAS available right now is theSynology Diskstation DS1522+ . You can't go wrong with this NAS as a powerful, robust option, complete with excellent supporting applications. Read on to find all of our recommendations for NAS devices.
Synology Diskstation DS1522+ specs: Drive bays:5Max capacity: 108TBMax w/expansion units:270TBRAM:8GB DDR4(32GB max)1GB Ethernet ports:4 10GB Upgrade:with Gen3 x2upgradeUSB 3.2ports:2 eSATA ports:2M.2 slots: 2
By far, the standout feature of any Synology NAS is the company's exceptional Diskstation Manager (DSM) software. While the Synology hardware is on par with many other NAS offerings, it's when that hardware is combined with the DSM software that Synology's offerings truly become noteworthy.

Featuring five hard drive bays by default and expandable up to 15 bays total, the DS1522+ is an economical NAS solution with plenty of room to expand as the user's data storage needs grow.
Running Diskstation Manager, this NAS option comes with Synology's suite of enterprise backup solutions. This includes Active Backup for Business which allows users to backup Windows PCs, VMs, SaaS applications like Microsoft 365.
Also included is Synology's Hyper Backup software, which allows you to back up your entire NAS or specific files and folders to most major cloud service providers. This flexible and free backup software gives the user enterprise-grade tools in an easy-to-understand format. This makes setting up a proper 3-2-1backup environment a breeze, no matter what or how many devices you're responsible for.
"It's like the cool kid on the block that can handle all sorts of data and has a knack for impressing tech enthusiasts and small businesses alike," says user Kacper Rafalski, demand generation team leader at digital acceleration company, Netguru.

TerraMaster is a solid storage space at a budget-friendly price. We found the user interface to be clean and well done and the overall usage experience to be solid. Now, to be clear, this is not a Synology, but that device is considerably more expensive.
TerraMaster is upping its game with the F4-423. Instead of a budget device, this is a performance machine, but at a mid-tier price. It's got two high-speed Ethernet ports, an HDMI port that lets you turn this into a media center server, and TerraMaster's clean UI.
Overall, this is a solid offering for higher-stress loads at a reasonable price. Cheaper, two-bay options are also available.

If you're interested in exploring the capabilities of NAS devices but aren't ready to take the plunge on a full rig -- yet -- you may want to consider the SSK 2TB portable NAS.
To be clear, this product doesn't have bays and is more akin to an external storage drive than a full NAS. However, it's cheap and provides a way to set up a personal cloud that can be accessed remotely via your PC, smartphone, and other mobile devices.
Keep in mind, though, that this is a mechanical hard disk so you shouldn't treat it like a typical external SSD drive, which tends to be quite rugged. This$126 device is best kept safe on your desk.
View now at Amazon's top pick for the best NAS available right now is the Synology Diskstation DS1522+. You can't go wrong with this NAS as a powerful, robust option, complete with excellent supporting applications, but if this model doesn't suit you, below are the top features to consider with alternatives:
Best network attached storage | Price | Bays | Max capacity | Ethernet |
Synology Diskstation DS1522+ | $700 | 5 | 90TB | 4 1GB ports |
ASUSTOR Lockerstor 6 Gen 2 | $835 | 6 | 120TB | 2 2.5GB ports |
WD My Cloud EX2 Ultra | $190 | 2 | 36TB | 1 1GB port |
TerraMaster F4-423 | $500 | 4 | 80TB | 2 2.5GB ports |
SSK 2TB Portable NAS | $126 | N/A | 2TB | 1 port |
So, how should you choose? In this case, the decision tree is pretty straightforward. You need, of course, to determine your budget and storage needs. Almost all vendors offer models in two bays (room for two drives) and up.
If you need a ton of storage, get more bays. But if you are new to the world of NAS devices, perhaps consider an entry-level or portable solution to familiarize yourself before investing in more powerful, heavy-duty gear.
From there, here's a quick chart to help you make your decision.
Choose this best network attached storage... | If you want... |
Synology Diskstation DS1522+ | The best overall NAS. By combining solid hardware and a best-class DSM software, this unit promises comprehensive storage for small businesses and remote workers alike. |
Asustor Lockerstor 6 Gen 2 | The best NAS from a reputable brand. This model also features six hard drive bays, support for four M.2 sticks, and uses the ADM 4.0 operating system. |
WD My Cloud EX2 Ultra | The best value storage with solid performance. This entry-level model will add considerable value to your network. |
TerraMaster F4-423 | The best mid-tier NAS with a nice user interface. Coming at a mid-tier price, it still has two high-speed Ethernet ports, an HDMI port, and accounts for higher stress loads. |
SSK 2TB Portable NAS | A portable, less expensive, and less powerful option. While this portable NAS drive does provide you with a private cloud, it's more akin to an external hard drive than a typical NAS setup. |
Here at , we have personal expertise in NAS devices dating back decades. Furthermore, we combine rigorous testing, verified customer reviews, and conversations with real-life users to select these NAS models, with a nod to user-friendly interfaces, performance, a model's strengths and weaknesses, and, of course, the price point.
User-friendly interface:We selected NAS models that are easy to set up, include software models that promote easy use, or even have sharing and collaboration abilities.
Fast performance:Unlike some cloud storage services, a NAS streamlines uploads and downloads, especially for video-editing tasks.
Strengths and weaknesses:No model is perfect -we know that. So, we included the pros and cons of each model to see which features are most beneficial to your security, setup, and workflow. This includes whether or not they are considered portable.
Price:Many shoppers are on a budget, so we always look at a product's price point and take that into consideration. The initial cost can be expensive, but in comparison to the cost of long-term cloud subscriptions, you can end up saving, over time.
There is no law that says you need to buy a pre-built box from a vendor. You can repurpose an old PC or even build a very custom NAS solution to meet your exact needs.
author and resident hardware expert David Gewirtz has built his own NAS boxes for years, including some that were highly customized. But as the NAS offerings from vendors like Synology, QNAP, and Drobo got better, the need to build his own diminished.
If you're comfortable with the prospect of sourcing PC parts and building PCs, you'll probably want to go it on your own. But if you're new to PC building, buying an appliance NAS is probably the way to go.
Most NAS devices (and all the ones we're recommending here) support RAID. RAID stands for Redundant Array of Inexpensive Disks. RAID technology takes advantage of the fact that you have multiple hard disks with multiple spinning platters.
"That's geek speak for Redundant Array of Independent Disks. Imagine a super team of hard drives, working together to keep your data safe and accessible," Rafalski explains. "It's kind of like having multiple copies of your favorite book - if one gets lost or damaged, no problem, you've got backups!"
One form of RAID allows you to write on one, then the other to increase speed. But the RAID we're most concerned with here is mirroring.
A well-implemented RAID array will allow one drive to completely fail without losing any data.
NAS is network-attached storage. That's storage that's on your network. DAS is directly-attached storage, and that's storage plugged right into your computer.
If you have more than one computer on your network, work with a group, or otherwise need to share files, a NAS is the way to go. If you're doing high-performance video production on a single machine, you might want to connect a DAS device right to your machine so there's no delay.
Rafalski comes through with another analogy that makes things easier to understand. "Think about it like this. DAS is like having a personal bookshelf right next to your desk. Quick and easy to reach, but only for you," he says. "NAS, on the other hand, is like a library -- everyone connected to the network can access it, even remotely. NAS is all about sharing and collaboration, whereas DAS is like a superfast personal hard drive."
While our top recommendations are above, we wanted to also showcase some other worthy alternatives, including different features, price points, and bay counts.
An affordable desktop NAS alternative is the 2-bay QNAP TS-233-US.
