Best NAS drives for Mac

Editor’s note: On April 3, 2023, Western Digital reported that its My Cloud servers had been hacked and an unauthorized party “obtained certain data from its systems. The company is investigating the issue.

You’re spoilt for choice when it comes to Western Digital’s My Cloud range, with several models available for home users and small businesses, as well as a number of Expert and Pro models for larger organizations.

The original single-drive My Cloud is getting a bit old now, but it’s still around and extremely affordable. However, you’re probably better off getting the newer My Cloud Home model shown here, which is a little more expensive but is faster and provides additional features such as support for the Plex Media Server software (although that’s probably not a must-have for Mac users).

It comes with a range of storage allocations; 8TB should be more than enough for most homes, as well as small offices and self-employed users. The slimline white-and-silver unit is neatly designed and only measures 2in wide, so it’ll sit easily on your desk or on a shelf close to your router without taking up too much space.

There’s also a larger dual-drive model, called the My Cloud Home Duo, which houses two matching drives and offers considerably more storage. That provides RAID 1 mirroring for extra data protection, but if you want more sophisticated RAID features, as well as the ability to install and remove drives yourself, you’ll need to step up to the My Cloud Expert or My Cloud Pro models.

Western Digital always does a good job with Mac support, and the My Cloud Home is no exception, with apps that handle a range of tasks quickly and easily. The iOS app can perform automatic backups of your photos and videos, while the Mac app lets you use Time Machine for your backups (and there are Mac and Windows versions of the apps available too).

There are some nice touches too, such as the ability to right-click a folder on your Mac and automatically sync the contents of that folder on to the My Cloud Home. That will be handy for people who want an extra backup of their current work files or projects in addition to the basic Time Machine backup. You can also right-click any file that is stored on the My Cloud Home and send a download link in order to quickly share that file with friends or colleagues.

And, if you also use an online backup service, such as Dropbox, then you can sync the contents of your Dropbox account on to the My Cloud Home too. You can even back up photos and albums from Facebook on to the drive for safekeeping if you want to.

There are a couple of rough edges. You can’t simply double-click the drive’s icon on the Mac desktop in order to open the drive and then drag-and-drop to copy folders or files on to the drive. For some reason you have to open the app’s pulldown menu and view the contents of the drive through the app instead. You can’t create individual user accounts on the Mac either, so you’re forced to use the app on an iPhone or iPad if you want to invite someone else to create their own personal folders on the My Cloud Home drive.

Most Mac users will have an iPhone or iPad, of course, but we’d like to see the Mac app updated to allow you full freedom to control the My Cloud Home with your Mac as well.

Many people now rely on cloud storage, such as Apple’s iCloud Drive or Dropbox, for personal use or working from home, but Synology is one of the few companies that still makes conventional NAS drives that provide physical storage for home networks and small offices. The latest addition to its range is the Diskstation DS723+, which provides an affordable and easy-to-use storage system that can be further expanded in the future if required.

The compact drive enclosure measures just 166mm high, 106mm wide and 223mm deep, so it’s easy to set up on your desk or any convenient shelf. There are two bays for hard drives on the front, along with two small slots for SSD drives that are located on the underside of the unit. Advanced users who want to configure their own system can buy the DS723+ as an empty enclosure (unpopulated) for around £575/$450 and then provide their own choice of HD or SSD drives. Or, if you’re looking for a simple, all-in-one storage system then some of Synology’s specialist dealers also sell the DS723+ with drive units already installed (populated). The price for ‘populated’ drives will obviously  depend on the amount of storage you require, but the 8TB model that Synology provided for our review should cost around $800/£850. Prices do vary widely online, though, so it’s definitely worth shopping around to find the best price (the starting price quoted above will rise depending on the storage options.)

There’s a Gigabit Ethernet port on the back of the for connecting to your home or office network, but the DS723+ also has two expansion ports that allow you to upgrade to 10 Gigabit Ethernet if required, and even to connect some additional drive bays so that you can add even more storage in the future. Synology’s manuals may look a bit daunting for people who haven’t used a NAS drive before – there’s a 50-page PDF just for the initial set-up process, and another 80-page manual covering all the features provided by Synology’s DSM software (Diskstation Manager). However, you don’t have to memorise all that info straight away, as there are quick and easy apps for iOS, Android, Mac and PC that can help you with the set-up process, and we had no trouble at all connecting the DS723+ to our office network and then using the apps to connect our Mac and iPhone to the drive.

Western Digital’s My Cloud Home drive provides a quick and easy option for home users who aren’t familiar with NAS drives and networking technology. In fact, the company doesn’t even call it a ‘NAS drive’, opting for the more user-friendly ‘personal cloud’ label instead. (If you feel a bit more comfortable with jargon such as NAS and RAID, you might want to step up to WD’s ‘expert’ range with the My Cloud EX2 Ultra instead.)

The EX2 Ultra is a no-compromises NAS drive with additional features and customisation options, while remaining affordable enough for home users or self-employed people, such as photographers or designers, who need a really reliable backup drive for important work files.

It’s a ‘two-bay’ drive that holds two separate hard drives, and allows you to remove the top panel so you can remove the drives for repairs or adding more storage in the future. You can buy the EX2 Ultra with a pair of drives pre-installed, with a wide range of prices depending on the storage you select.

WD includes its high-performance Red Drives and 1GB of memory to help the EX2 Ultra multi-task when different people are using the drive on the network at the same time. There’s a Gigabit Ethernet port for connecting to your network, and the EX2 Ultra also has two USB ports that allow you to connect an external USB drive for additional storage.

Alternatively, you have the option of buying the EX2 Ultra ‘unpopulated’ – with no drives at all – and then providing your own drives to suit your particular needs. This is the best option if you think you might want to add extra storage in the future, and installation is really easy: the top panel simply pops open at the press of a button to reveal the internal drive bays.

Using two separate hard drives also means the EX2 Ultra can work as a ‘RAID’ drive, with either RAID 0 – which improves performance by splitting files across both drives (called ‘striping’) – or RAID 1 ‘mirroring’, which makes separate copies of your files on each drive for extra reliability. If you want even more safeguards for your important files, there’s also an option to back up data from the EX2 Ultra on to an external hard drive connected to one of its USB ports.

Despite all these extra features, setting up the EX2 Ultra is still very straightforward, as the drive supports Time Machine for automatically backing up files from your Mac. There’s also a My Cloud app for iOS/iPadOS and Android that allows you to back up and share files using non-Apple devices as well.

The app provides remote access to the drive over the internet, and there’s a web browser interface also available for Macs and PCs, which allows more advanced users to configure RAID settings and features such as the FTP server – and even to use it as an ‘iTunes Server’ for streaming music across your network.

It’s worth checking out the changes made by the My Cloud OS 5 software update, however; this adds several new features, but reduces compatibility with some web services.

A five-bay drive such as the 5N2 might be unnecessary for home users, but Drobo has a well-deserved reputation amongst professional and creative users who need a versatile and reliable NAS drive.

The 5N2 is more expensive than most of its rivals. But while the nondescript black box isn’t much to look at, it’s absolutely packed with features designed to keep your data safe and will earn its keep in your office.

Drobo claims to offer “the benefits of RAID without the complexity”, and the company does a really good job of helping newcomers to get started and showing you how to use the 5N2.

Even before you turn it on or install a single hard drive you’re instructed to go to the Start page on the Drobo website. This shows how you can simply slot the drives into the 5N2 and then connect it to your router – and the 5N2 even has two Gigabit Ethernet ports, which can be ‘bonded’ together to provide higher performance for devices such as the iMac Pro, with its 10GB Ethernet interface.

After the initial setup, you’re prompted to download Drobo’s Dashboard app for Macs and Windows PCs. This installs a pulldown menu into the main menu bar at the top of your Mac’s screen, providing instant access to the drive’s main features.

However, you probably won’t need to use Dashboard very often, as many of the drive’s features work automatically. Once the drives have been installed there’s a series of lights on the front panel that indicate the status and health of each drive, along with a row of blue lights that act as a capacity gauge to let you know when you’re running out of storage.

The 5N2 also allows you to ‘hot-swap’ drives, removing and replacing faulty drives, or simply adding some extra storage without having to restart the unit. It even has a small built-in battery that can protect the 5N2 from power failures, keeping it running long enough to complete the current task and then shut down without losing any data. And, rather than offering conventional RAID modes the 5N2 uses Drobo’s own BeyondRaid software to automatically protect your data (which comes in handy if, like me, you can never remember the difference between RAID 0 and Raid 1).

In fact, most people will probably only use Dashboard to set up user accounts for other people who also need to use the 5N2 for network storage, or to set up Time Machine backups for your Macs – which you can do at the same time as setting up the ‘share’ for each user. If you want to explore further, Dashboard also allows you to install additional apps, such as the Plex media server, or Drobo Access, which provides remote access over the internet. There are iOS/iPadOS and Android versions of Drobo Access available too, so you can view and edit files stored on the 5N2 with your mobile devices, along with a DroboPix app that allows you to back up your photos and videos.

It’s probably too expensive for most home users, but the admirable ease of use provided by the Drobo 5N2 makes it an ideal choice for small businesses and creative users who may not have used a NAS drive before. And, with failsafe features such as its internal battery, the 5N2 can offer rock-solid reliability for protecting your most important data.

The only problem is that Drobo says that it has been “severely impacted” following Coronavirus and related production delays. As a result there are stock shortages.

Buffalo’s LinkStation 220D is a versatile and affordable NAS drive that’s suitable for both home and business users. But, as we’ve seen with Buffalo in the past, its products sometimes lack the straightforward ease of use that Mac and iOS users take for granted.

The LinkStation 220D is a dual-bay NAS drive that houses two separate hard drives. You can buy it ‘unpopulated’ – with no drives at all – and then provide the drives that you want to use for yourself. Alternatively, you can buy it with 2TB, 4TB or 8TB.

There’s also a more expensive model called the 220DR that’s designed for use with Western Digital’s high-speed Red drives, but the standard 220D model that we review here should be perfectly adequate for most homes and small businesses.

The dual-bay setup also means you can use the LinkStation as a RAID drive, supporting either RAID 0 for maximum performance, or RAID 1 for maximum data protection (storing separate copies of your data on both drives). Future upgrades are simple as well, as you can quickly remove the front panel of the LinkStation and pull out the drives by their handles, with no screws or tools required. There’s also a USB port on the back of the LinkStation that can be used to make additional backups to an external USB drive for extra safety.

Getting started is quite straightforward, as the 4TB LinkStation that we tested automatically showed up on our office network once we connected it to our router with an Ethernet cable. That allowed us to simply drag-and-drop files on to the LinkStation for quick backups, but things get a bit more complicated when you start to move beyond the basics. The LinkStation does work with Time Machine so that you can back up your Macs over the network, but setting up Time Machine and a ‘shared folder’ for your backups proved rather complicated.

Buffalo’s NAS Navigator app for Macs allows you to view the LinkStation on your network and displays basic information, such as its IP address. However, using any other features requires you to open up a web browser in order to view the LinkStation’s web interface.

This does include a variety of useful features, including Time Machine support, remote ‘web access’ for when you’re away from home or the office, BitTorrent downloads, and the ability to use the LinkStation as an iTunes server for streaming your music across the network. But this browser interface is very complicated and won’t be easy for non-technical users to understand – and Buffalo’s 125-page jargon-heavy PDF manual doesn’t really make life any easier.

And neither do Buffalo’s mobile apps. Buffalo provides two separate apps for iOS devices: Smartphone Navigator for basic setup, and WebAccess to provide access to your files via Wi-Fi when you’re out and about.

These apps are getting on a bit, and some users have complained that they’re unreliable. In fact, the apps seemed to run on our office iPhone and iPad without any problems, but they’re still quite complicated and unhelpful for people who aren’t familiar with NAS drives and networking technology.

So while the LinkStation is a good option for more experienced home or business users who already know a bit about NAS drives, it’s probably not the best option for first-time users who are still learning the ropes.
