Best NAS devices of 2020: top Network Attached Storage for the home and office
The best NAS devices are your ideal storage solutions if you have some irreplaceable files and require remote access to them. They are a reliable way of making sure you have access to your files when you need them, wherever you are, while keeping them secure.
These Network Attached Storage solutions allow different devices to access its files – both via local network and via the internet – as easily as if they’re directly installed in those devices. This means you can access your important documents anytime from the other side of the world, which means you won’t have to store such files in an external hard drive
The best NAS devices offer that remote access while guaranteeing that your files and folder are kept safe and secure. This means you can access your important documents anytime from the other side of the world without worrying that they’re susceptible to theft and other threats. And, because they are platform-agnostic, it doesn’t matter what OS is on your device. You’ll still be able to gain access with whatever you have on hand.
Before you purchase the first NAS device you can find within your budget, there are a few things you need to consider. The amount of storage space on hand is definitely a priority here. You’ll want to look ahead at how much you’ll actually need, not just now but in a year.
Bear in mind also that not all of the best NAS devices use hard drives. Some hold multiple hard drives that you have to buy separately, which may be a tad more complicated but also gives you the flexibility in storage space and speed. Also, if you do some bargain hunting, you could save some cash buying the hard drives separately.
You’ll want to consider your backup and redundancy needs as well. Many of the best NAS drives are able to hold more than one hard drive and can mirror that hard drive in case of failure. So if one hard drive does go, you don’t have to worry. It’s all backed up on another. Also, the best NAS devices allow you to use an external drive as a backup.
Whether this is an extra precaution or because you want to take the data with you, it’s a useful feature.
Take a look at our picks for the best NAS devices for your needs. And if you already have a NAS device and want to boost its storage, take a look at our choices for the best hard drives.

Even with a NAS device loaded with multiple hard drives you may still want to keep an extra copy of your most important files and documents online. With a cloud storage provider like iDrive you can rest easy knowing you have multiple copies of your files stored in separate places for redundancy.

1. WD My Cloud Personal NAS drive
Simple, yet fast
Capacity: 2TB, 3TB or 4TB | Interface: USB 3.0, Gigabit Ethernet | Features: Remote file access, DLNA, iTunes Server
WD has attained quite significant success with its unashamedly consumer-friendly My Cloud products, which can stream to any DLNA-compliant device and be accessed via mobile apps for iOS and Android.
Advertised as a 'personal cloud,' this WD is one of the best NAS drives by any other name and starts at 2TB of storage (you can also get it in 3 or 4TB). Because it's a one-bay unit, it can't back itself up since there's only one drive. However, it can back up to an external hard drive thanks to a USB port on the back.

2. Seagate Personal Cloud 2-Bay NAS drive
Convenient network storage
Capacity: 4TB, 6TB or 8TB | Interface: Gigabit Ethernet | Features: Remote file access, media server software, RAID support
Continuing with the 'personal cloud' theme, this unit from Seagate takes its lead from My Cloud, while offering far larger capacities, along with dual bays for two hard drives. This allows the Seagate Personal Cloud 2-Bay NAS device to mirror the files from one hard drive to a second one, securing your files in case one of those drives fails.
We also appreciate the no-fuss appearance of this unit, meaning it fits easily under a router or on a shelf. Plus, it can work with cloud accounts – like Dropbox and Google Drive – and you can also use an app to share content to streamers, such as Chromecast and Roku.

3. QNAP TS-251A NAS drive
Feature-packed media NAS
Capacity: N/A | Interface: 2 x Gigabit Ethernet, USB 3.0 | Features: Remote file access, HDMI out, 4K media transcoding, DLNA
The QNAP TS-251A is an extraordinary NAS device that has more features than you can shake a stick – or the included remote control – at. It includes dual Ethernet ports, an HDMI out for connecting it to a TV and respectable hardware like the dual-core 1.6GHz Intel Celeron CPU and 4GB of RAM for hardware transcoding media files.
The QTS OS also lets you effortlessly install a variety of apps, from the Plex Media Server and file sharing apps to, surprisingly, a karaoke app, as well as running Ubuntu Linux for added flexibility.
Long story, short: this is an incredible NAS device, even if you do have to purchase the hard drives separately. Just factor that in to the overall cost.
4. Buffalo LinkStation LS220D NAS drive
A decent dual-bay NAS with built-in BitTorrent
Capacity: 2TB, 4TB, 6TB, 8TB | Interface: Gigabit Ethernet, USB 2.0 | Features: Dual bay, WebAccess apps, Apple Time Machine support
As one of the best NAS drives out there, this 2TB dual-bay unit (also available in 4, 6, and 8TB capacities) comes courtesy of Buffalo, the company that also produces the TeraStation line of advanced NAS units.
The key selling point of this model is that it can integrate directly with BitTorrent, which means that it can download files for you even when your PC is not on. You won’t need to worry as much about your downloads getting interrupted. Like many of the other devices listed, you can also stream to it via various devices, it's platform agnostic, and you can use it as an iTunes server.

5. Synology DiskStation DS1817 NAS drive
A beginner NAS with room for expansion
Capacity: : N/A | Interface: : 2 x 1GbE LAN, 2 x 10GbE LAN, 2 x USB 3.0, 2 x eSATA | Features: : Quad-Core CPU, Compatibility with up to 18 drives, 1,577 MB/s sequential read
Every now and then, a product comes along that challenges the conventions of their product category. The DS1817 is one such product. Most NAS devices that occupy the ‘value’ space tend to be underpowered and have little to no room for expansion. The DS1817 breaks the norms by letting users fill the included eight drive bays with whatever they desire, so that you can get as much (or as little) storage as you want. On top of this massive expandability, which helps rank it as one of the best NAS drives available, the 10GbE LAN and Quad-Core CPU also mean that you’ll never be left wanting for performance.

6. WD My Cloud Mirror NAS drive
A unit that backs itself up
Capacity: 4TB, 6TB, 8TB, 16TB | Interface: Gigabit Ethernet | Features: Automatic backup, two hard drives, My Cloud mobile app
This two-bay unit can produce a mirrored backup of your data, duplicating your files on both drives, using RAID configuration. That's quite an advanced feature for a consumer unit. Just keep in mind that you end up paying quite a lot for that capability and WD's user-friendly presentation, including an easy-to-master, browser-based control screen.
This is a 4TB unit, though 6, 8 and 16TB units are also available. For extra peace of mind, you can also back up the contents to Dropbox.
7. Synology DiskStation DS1517 NAS drive
Expensive, but packs a punch
Capacity: : Up to 60TB, 180TB with expansion unit | Interface: : 4 x 1GbE LAN, 4 x USB 3.0, 2 x eSATA | Features: : Quad-Core CPU, Up to 15 drives with expansion units
Anyone looking at purely technical spec’s will instantly fall in love with the Synology DiskStation DS1517. Thanks to its quad-core CPU and up to 8GB of RAM, this NAS can reach sequential speeds of 111.4 MB/s write and 110.3 MB/s read without any trouble. Combining that raw performance with the DS1517’s expandability, and you have a formula for a NAS device that has undeniably earned its spot among the best NAS drives on the market. Just know that the DS1517 isn’t cheap, and unless you’re a creative professional, or you’re looking for a NAS for a small business, it might be a bit too much.

8. WD My Cloud EX2 Ultra NAS drive
The small business version of the My Cloud Mirror is now even better
Capacity: 4TB, 8TB, 12TB, 16TB | Interface: Gigabit Ethernet, USB 3.0 | Features: Remote file access, RAID features, My Cloud OS 3 software
Featuring RAID capabilities found in pricier and more intricate NAS devices, as well as offering Microsoft Active Directory support, this box is designed for small business use. That’s without mentioning that it can also act as a file server, FTP server, backup server and P2P download server.
In addition, WD's EX series is available in diskless variants, though this price is for the 4TB version. 8TB, 12TB and 16TB units are also available to purchase. If you don't need any of this extra stuff, then go with the My Cloud Mirror.
9. Western Digital DL4100 NAS drive
Excellent backup for a wide variety of users.
Capacity: 8TB, 16TB, 24TB | Interface: 2x Gigabit Ethernet, 2x USB 3.0, USB 2.0 | Features: Dual LAN, 2GB RAM (expandable up to 6GB), NTP Client
If you're looking for one of the best NAS drives to help manage your backup needs, the DL4100 might be worth a look. One of the coolest features of this device is its web dashboard, which provides users options for backing up to cloud services such as Dropbox and Box. Additionally, it has the ability to set up SMS and email alerts in case the system fails for whatever reason.
As far as storage options go, the DL4100 is equipped with four drive bays and comes with your choice of four configurations. Despite some annoying issues with wireless transfers, we found that the DL4100's 1.7GHz dual-core Atom processor and 2GB of RAM (configurable up to 6GB) performs admirably. Combine this with a simple setup and cloud connected web apps, and you have an interesting backup device on your hands.
