If you have serious storage requirements, and you make protecting your data a high priority, then here are six of the very best NAS (Network Attached Storage) drives for work and play.
Welcome to our guide to buying the best external hard drive or backup hard drive in 2019. When looking to buy the best external hard drive for your needs, there are quite a lot of things you need to consider - and this guide will help you.
Plus, with Amazon Prime Day 2019 rapidly approaching, there's a good chance that we're going to see some major price cuts to the best external hard drives out there. If you do find a killer deal for any of the drives on this best external hard drive list, then you can buy in full confidence that you're getting a brilliant external drive for your money.
When buying the best external hard drive for your needs, you need to make sure you get a device that can safely and securely store your important files. Reliability is of the upmost importance here, as you do not want to buy an external hard drive that fails on you - making you lose all your important backups.
The best external hard drives will also be quick - either because they use SSD (Solid State Drive) technology, or because they use the latest connectivity technology, such as USB-C.
The biggest deciding factors when it comes to data transfer rates is the connection the drive uses, and whether it is a standard hard drive or a solid state drive (SSD). Many external hard drives use USB 2.0 connections, but for faster speeds you'll want USB 3.0 or ideally the newer USB Type-C connection. You'll need to ensure your PC or laptop also has a USB Type-C port.
You'll also need to think about how much storage space you need. The best external hard drives offer a range of capacities. We'd recommend 500GB to start with, as that gives you plenty of space to store your files without costing too much money.
However, if you deal in large files, such as high resolution photos and videos, then you may want to consider buying a bigger drive, with external hard drives offering terabytes (TB) of storage space.
Buying the best external hard drive for your needs involves figuring out how much space you need. You don't want to buy an external hard drive that's too small, and end up running out of space, but neither do you really want to pay over the odds for storage space you'll never need.
So, we've listed the best external hard drives money can buy in 2019. Each external drive (or backup hard drive) on this page has been carefully picked to make sure it offers fast data transfer speeds – essential if you move lots of big files regularly – while also offering sturdy build quality so you don't have to worry about them breaking and losing your files.
When buying the best external hard drive for your needs, there are certain things you need to take into account. For example, you'll want to make sure you have a drive that offers fast data transfer speeds.
In this guide we list the best external hard drives with both traditional hard drives and faster (and more expensive) solid state drives.
Still, the best external hard drives are also dependable and rugged, so you can safely store your data without worry. The best external drives will also be light enough to carry in your bag, with large capacities so that you can keep your data safe when travelling.
There's a huge range of external hard drives on offer, so we've put together this list of the best external hard drives to help you find the perfect one for your needs.
1. Buffalo MiniStation Extreme NFC external hard drive
Wireless security
Capacity: 2TB | Interface: USB 3.0
Today's best Buffalo MiniStation Extreme NFC 2TB deals
An external hard drive you can buy without breaking the bank, Buffalo's MiniStation Extreme NFC could be your match made in heaven.
With compatibility for both Mac and Windows machines, the Buffalo MiniStation Extreme NFC is very flexible, and comes with a rugged case that's dust and water resistant, along with a built-in USB 3.0 cable.
Not only is your data kept protected from knocks and drops with the rugged shell, but it's also got 256-bit AES security features and NFC (Near Field Communication) features as well.
Essentially it allows you to unlock the drive to get to your files quickly and easily by tapping the supplied NFC card onto the drive's body. Pretty neat!

2. Western Digital My Passport Ultra 4TB external hard drive
Comes with Encryption and a long warranty
Capacity: 4TB | Interface: USB 3.0
The latest generation of the Western Digital My Passport Ultra range of external hard drives has landed, coming in sizes from 1TB to 4TB. It features cloud storage and 256-AES encryption, along with WD's own software suite.
It is a good performer when it comes to data transfer speeds but doesn't come near the top of the leaderboard. Unsurprisingly, it doesn't reach the top speeds of solid state external drives, but for external hard drives based on traditional HDDs, this is the drive to consider.
3. Samsung T5 SSD external hard drive
The best external SSD of 2018
Capacity: 250GB, 500GB, 1TB, 2TB | Interface: USB Type-C
If you'd rather have an external hard drive that took advantage of solid state drive (SSD) speeds, then the Samsung Portable SSD T5 is definitely the best external hard drive for you. Samsung has a brilliant reputation for external SSDs, thanks to products like the T3, and the T5 builds on its predecessor by adding a fast USB Type-C connection that ekes out every last drop of performance from the solid state drive inside. Of course, it's also backwards compatible with USB 3.0 and USB 2.0 if your PC doesn't have USB Type-C. It's expensive, but it's well worth the cash.

4. Adata SD700 External SSD
Capacity: 256GB, 512GB or 1TB | Interface: USB 3.0
The Adata SD700 will suit those looking for a rugged storage device that can provide ample capacity without costing too much. It performs superbly well and remains the only SSD we've seen that is IP68 rated.
Thanks to the solid state drive that resides in this external hard drive, it's a lot faster than external drives that use traditional spinning hard drives - so you're getting great transfer speeds as well as rugged protection.
It also comes in capacities up to 1TB, so you don't have to worry about missing out on storage space just because it uses an SSD - this drive really does hit all the right notes.
5. WD My Book Duo 4TB external hard drive
Capacity: 4TB | Interface: USB 3.0 x 2
If you're looking for the absolute largest capacity external hard drive, then the WD My Book Duo 4TB is the one to get, offering a huge 4TB (you can also get versions with up to 20TB) of storage space over two hard drives.
If you don't mind sacrificing some of the ample storage space you can set the drives up in a RAID array, so you have file backups of your files should one of the drives die.
This USB 3.0 drive has many of the features of a fully-fledged NAS device (including a high price), and if you have a router with a USB 3.0 port you could use this as a network attached storage device in its own right.
The device, which comes with two-year warranty, has 256-bit AES hardware encryption, and automatic backup software (WD SmartWare Pro).
Worth noting that the enclosure used is fully serviceable and that WD ships the drive already pre-formatted for Windows users (NTFS).
6. Buffalo MiniStation Thunderbolt external hard drive
Best Thunderbolt external hard drive
Capacity: 1TB, 2TB | Interface: Thunderbolt, USB 3.0
If you have a device with a Thunderbolt port, then this is a great option, as it provides twice the speeds of standard USB 3.0 drives. It's also not especially expensive compared to other Thunderbolt drives. The price is kept down due to its use of a traditional hard drive, rather than an SSD, which limits the potential speeds. It also comes with a USB 3.0 port for people without access to Thunderbolt.

7. Seagate Backup Plus Desktop Drive 5TB
Capacity: 5TB | Interface: USB 3.0
Today's best Seagate Backup Plus Desktop Drive 5TB deals
If you want to combine speed and capacity, then the Seagate Backup Plus Desktop Drive 5TB is definitely worth considering. It comes in a range of sizes up to 8TB and it beats the competition when it comes to read and write speeds as well.
On top of this storage and speed, you get a decent amount of peace of mind thanks to Seagate's lower than average failure rates, especially in bigger capacity hard drives.
You also get backup software, and the drive is compatible with both Windows and Macs, though it's formatted for Windows out of the box unless you go for a Mac-specific hard drive - though these are more expensive.
8. Western Digital My Passport Wireless Pro external hard drive
Capacity: 2TB | Interface: USB 3.0 and Wi-Fi
Today's best Western Digital My Passport Wireless Pro deals
Even if we had mixed feelings on past versions of the My Passport Wireless, the 2016 'pro' variant of the external HDD restores faith in the Western Digital name. The design, for one, has been overhauled and no longer resembles the My Passport Ultra or My Passport for Mac. Instead, there's now a more premium feel to the My Passport Wireless Pro. It resembles an external DVD drive, but considering the onboard SD card slot, don't worry about getting it confused with anything else. For photographers, this will make the Wireless Pro stand out.
For everyone else, there's a massive 6,400mAh battery built into the device. This lets the drive be used completely free of wires over 2.4GHz or 5GHz channels. When it's wired up, however, don't expect cutting edge connection tech, as the My Passport Wireless Pro uses only USB Type-B to Type-A. Completely absent is the latest and greatest USB-C connection.
Where the My Passport Wireless Pro compromises on affordability, it's able to benefit in just about every other area. Of course, not everyone needs a wireless hard drive or SD card support, but for those who do, it's almost essential.

9. LaCie Porsche Design Mobile Drive 4TB
Capacity: 4TB | Interface: USB-C
Best Nas Drives For Mac
Today's best LaCie Porsche Design Mobile Drive 4TB deals
You may have stumbled upon the LaCie Porsche Design Mobile Drive when perusing the Apple website for USB-C accessories. There's a reason for that: the Porsche Design ships with both USB Type-C to Type-A and USB Type-C to Type-C connectors, making it a worthy candidate regardless of your setup.
It's expensive for an external hard drive, don't get us wrong, especially if you're in the market for the top-end 4TB option. On the other hand, this is an HDD that could theoretically output speeds of up to 5Gbps, if it weren't hindered by the limits of SMR (Shingled Magnetic Recording) technology.
Comprising five 800GB platters in a 15mm form factor, the LaCie Porsche Design Mobile is an excellent challenger to the Seagate M3, though it's notably bigger in both weight and dimensions.
Sure, it packs an extra convenience factor in the form of USB-C, but it should be noted that the Porsche Design Mobile is still limited to USB 3.0 speeds. Plus, even an aluminum finish can't prevent it from clashing with your Rose Gold MacBook. Nevertheless, LaCie's offering is the best USB-C external HDD money can buy, at least for the time being.

10. iStorage diskAshur 2TB external hard drive
Best for security
Capacity: 2TB | Interface: USB 3.0
Mac Compatible Nas
Typically, iStorage hard disks cater best to governments and multinational organizations around the world, for good reason too – they offer tight security like no other drives around.
If someone tries to tamper with your iStorage drive, you can configure it to self-desturct. What's more, the data is encrypted by the 256-bit AES protocol, with multiple forms of protection in place to ensure the bad guys don't get in no matter how persistent. When you consider all that extra security, the prices won't scare you away either.
Sure, it's still expensive, four times the price of an equivalent 2TB drive, and unlikely to be the most nimble performer. But, you're paying for a product that's virtually uncrackable. Bear in mind, though, you'll get no help from the manufacturer if things go awry and you lose your password.

Our Top Picks
Best Streaming: Western Digital My Cloud EX2
For personal use, the Western Digital My Cloud EX2 ultra network attached storage is the king of the hill. Available in a slew of storage options, the high-performance dual-core processor and 1GB of RAM combine to provide outstanding performance for both media streaming and file transfers. The two-bay unit creates a mirrored backup of all your personal computer files and folders utilizing RAID configuration. For a consumer box, the inclusion of RAID technology is both notable and welcomed and, when combined with Western Digital's user-friendly operating system, it's an overall enjoyable experience. Backups can be scheduled or synchronized across computers and My Cloud devices mean that even if you miss a manual backup, you're still covered.
Additionally, the My Cloud makes it easy to share files publicly by creating a private link that can be user-limited or can allow full-access to anyone with the link. Streaming media fans will love the inclusion of Plex Media Server, which allows quick and easy support for sharing files directly to a PC, smartphone or gaming console in its original uploaded quality. Add in extras such as Mac and Windows compatibility and 256-AES encryption and you'll find plenty of reasons to grab this backup device for all the peace of mind you need.
Best Budget: Synology DS115J
If you're running on a lean budget, the Synology DS115j offers both sharp looks and good performance at a welcoming price tag. The DS115j provides both an easy way to automate simple tasks or backup your multimedia files for later playback all while accessing everything from Synology's smartphone apps. Options such as Cloud Stations and Cloud Sync provide quick and easy access to files across multiple devices, including cloud services such as Dropbox, Google Drive and OneDrive. Fortunately, once these files are loaded onto the NAS, Synology provides a simple backup solution with file protection to back up everything to another NAS, a cloud service or a separate external device for redundancy across the board. With capacity up to eight terabytes of space (hard drives sold separately), there's still plenty of room on this budget all-star for added services such as 24/7 home surveillance with Surveillance Station, which allows an owner to view and monitor live streams on both desktop and mobile devices.
Best Storage: Synology DiskStation DS918+
With up to nine drives of storage available for data, the Synology DiskStation DS918+ is a smart option for NAS shoppers looking for a single solution to hold all their data. Whether it's 4K video or thousands of photos or documents, external hard drives can only hold so much — a NAS can go well beyond for homes or small offices. Two large 120mm fans on the rear keep everything cool, and there are dual RJ-45 ethernet points with support for link aggregation. A rear eSATA port adds to the storage potential in the event the drive bays are used up. Inside the DS918+, the hot-swappable and easily removed trays can be removed to make room for even more RAM. Capable of supporting up to 48 TB in total, each drive bay can hold up to a 12TB drive which, when paired with the eSATA port, enables the DS918+ to support up to 108TB max on a single volume. Write speeds are handled at 225 MB/s for reading system files and 221 MB/s for writing files.
Best Media: Qnap TS-251A
The Qnap TS-251A is a dual-bay (front-accessible) box that features an Intel Celeron dual-core processor, 2GB of RAM, twin Ethernet inputs, a slew of USB ports and an SD card slot for quickly copying files directly to the box. It also has HDMI support on the rear of the box, which allows 1080p videos to play directly from the NAS to an HDTV. There's added support for HD video transcoding, plus DLNA and AirPlay (iTunes) streaming.
Popular services such as XBMC and Plex's media server provide third-party support to help move media directly from the NAS to a media-playing device, including a smartphone or tablet. Additionally, the TS-251A supports the Roon streaming service (priced separately), which upscales nearly any type of audio file to near studio-quality. You can even attach a USB TV tuner and record cable shows or decode and transcode 4K H.264 videos. Beyond multimedia, the Qnap performs exceptionally well as a traditional NAS with good RAID recovery, remote access and powerful virtualization capabilities.
Best for Small Businesses: Synology D216II+
While this is a standout two-bay device, there's no included storage out of the box on the Synology D216II+, allowing you to choose your own drive capacity and speed. The swappable drive tray design offers easy installation and care while allowing terabytes of data to fit neatly in your pocket over the cloud with Synology's mobile app. With built-in 4K Ultra HD video transcoding, the DS216II+ is as much a multimedia machine as it is a 24/7 security solution with intelligent monitoring and video management tools. Extras include advanced file management between the NAS and your computer, Cloud Sync for connecting to a slew of popular cloud providers, as well as a well-designed software interface for managing all the above. The lack of Ethernet and HDMI ports is notable, but is easily overshadowed by its integration into a business environment with admin support for monitoring and controlling access to files and folders.
Best for Home: Western Digital My Cloud EX4100
Western Digital's My Cloud EX4100 and its eight terabytes of storage space offers up a wide set of possibilities for home storage options. With plenty of room for photos, videos, music and files, the EX4100 helps protect your content with multiple RAID options all the way from RAID 0 to RAID 10. Powered by a Marvell Armada dual-core processor and 1GB of RAM, transfer speeds are excellent at a maximum of 114 MB/s upload and 108 MB/s download. The speedy performance will come in extra handy with Plex's Media Server, which allows EX4100 owners to stream videos, photos and music directly to a PC, smartphone, game console or other capable media player. Families can make use of collaborative sharing, where everyone can access all their most important files and folders in one place. In addition, the EX4100 is also ready to help protect the home with Milestone Arcus surveillance software that provides live feeds and records video with separately purchased cameras.
Best Splurge: Netgear ReadyNAS 626X00
Featuring unrivaled data protection, state-of-the-art backup recovery and the ability to support up to 120 users, the Netgear ReadyNAS 626X00 is the best NAS money can buy. With a maximum of six available bays for storage, the ReadyNAS can handle up to 60TBs of storage that can process at up to 20 gigabits per second for both business and media applications. It's powered by an Intel Xeon 2.2GHz Quad-core processor (the latest in 64-bit technology) and 8GB of RAM so the 626X00 can handle 4K streaming with ease and create virtualization desktops for secure office environments.
Safeguarded by five levels of data protection, business owners should feel secure against the loss of company files, databases or virtual images. The backup and recovery system is rock solid, allowing users to quickly restore from the latest backup and get back to work. With 10GbE Ethernet ports on the back of the hardware, there's support for a multitude of users all at once without any impact to data speeds.

How We Tested
Our reviewers spent 10 hours testing one of the most popular NAS devices on the market. To really get the full experience, they set it up in their home offices, connected various devices, and analyzed its performance. We asked them to consider the most important features when using this NAS server, from its design to special features like encryption and additional drive bays. We've outlined the key points here so that you, too, know what to look for when shopping.
What to Look for in Network Attached Storage
Additional drive bays - Basic NAS devices come with a single built-in hard drive. If you want your NAS to last a long time — and to be as flexible and redundant as possible — look for one that has multiple drive bays. This allows you to store more data, add an additional backup, and even hot-swap out defective drives in some models.
Media streaming capabilities - Most NAS devices can be used to stream media, but some are better at it than others. Some NAS devices even include an HDMI port and a remote, so you can plug right into a television without using a media center PC or streaming device as a middleman.
Encryption - NAS devices that include hardware-level encryption are much faster than devices that rely on software. Encryption is mostly important if you use your NAS to back up sensitive data that you don't want anyone to access. Even if you only access your NAS through your home network, encryption will protect you if the device is stolen.

Test Results: Western Digital My Cloud EX2 (Best Streaming)
What We Like
Simple setup
Lots of configuration options
Great performance
What We Don't Like
Instructions could be more detailed for different use cases
One of our testers was quick to sum up the benefits of this NAS server: 'It's nice to have a network device that's easily accessible, simple to set up, and works as backup/extra HD space,' he noted. 'I have a couple external hard drives for backup, and it's very nice to have something that I don't have to plug in, works across all my devices, and has a substantial amount of storage — and backup for that storage!' Although our testers loved that this device had many configuration options, they wished it had more detailed instructions for different use cases: 'Basically, I wish that it came with ‘NAS for Dummies,'' one reviewer said.
