Best External Hard Drives for Mac of 2017
External hard drives are used to backup large amounts of information outside of your Mac’s internal hard drive. Anyone who’s ever lost all of their data after a computer crash can understand how important that is. But there are other reasons to buy an external hard drive for your Mac.
Maybe you want to have all of your data available for when you get a new Mac. Or if you work with gigantic files that need more space than what your Mac’s internal hard drive has to offer. No matter what reason propels you to buy an external hard drive, we’ve compiled some of the best external hard drives for Mac the market has to offer to help you make an informed choice.
What is the difference between an internal and external hard drive?
It’s basically what the names suggest. An internal hard drive is the hard drive that comes inside your Mac or store-bought Windows system. While new internal hard drives have a ton of space compared to older ones (now measured in terabytes instead of gigabytes as in years past), it’s a good idea to have a backup of your work.
External hard drives work on your computer by connecting to it. You can transfer files off of your internal hard drive and put it on your external one. Likewise, you can view and transfer files from your external hard drive and put them back on your internal hard drive.
In a day and age when space is measured in terabytes, and file sizes are growing larger with advances in an array of technologies, it’s important to ensure you have the space you need to save your precious work and priceless media library; external hard drives were made for that.
How do external hard drives for Mac work?
External hard drives for Mac work pretty much the same as they do for a PC. The best external hard drives for Mac tend to connect to Macs via Thunderbolt or USB 3.0 cables. This allows for the fastest connectivity, generally speaking. Once connected, you can automatically or manually back up your files, depending on your preference.
Many hard drives work for both Mac and Windows operating systems. Some of these require no particular reconfiguration or installation (some are simply plug-and-play), though others require you to reconfigure for Windows usage or vice versa for Mac usage.
Drives that play well with both operating systems are crucial for families, offices, and classrooms where people might be on different operating systems and connecting to a single external hard drive.
Some external hard drives for Mac even feature automatic backups, so you don’t have to worry about doing something wrong manually. Furthermore, the better external hard drives tend to work with Mac’s Time Machine feature, which further simplifies and streamlines things.
How to keep your external hard drive running smoothly
Let’s face it: There’s nothing more terrifying to a computer user than hard drive failure, and that’s why people buy external hard drives—as a backup for “just in case.” But here’s the thing: If you don’t properly maintain your external hard drive, you could inadvertently cause it to fail and lose everything you worked so hard to save.
Here’s a few simple steps to keep your external hard drive healthy:
- Make sure the device you’re plugging your hard drive into is connected to a surge protector. Even short power surges can have lasting effects on electronics, so this is like computer basics — and super important.
- Always store your external hard drive in the position it was designed to be in: Some external hard drives can be placed either horizontally or vertically. However, many are just meant to be placed either one way or the other. Turning your hard disk the wrong way puts unnecessary strain on it which could ultimately lead to failure.
- Don’t expose it to static: This is also a computer 101 thing; while modern devices including hard drives seem so much sturdier than their older counterparts (and are in many ways), it’s always best to be safe rather than sorry.
The benefits of buying Max external hard drive
The number one benefit of buying an external hard drive for Mac is that you will have a backup of your files that’s trusted and in your care, a backup you always have access to without having to depend on a cloud, a backup you can access when offline. These alone are colossal benefits to buying an external hard drive for your Mac, but there are other considerations.
Anyone who has a lot of high definition video files on their computer knows how much space that eats up on their hard drive.
For professional video editors as well as hobbyists, who will probably have more HD vids on their Mac than anyone else, it’s crucial to have an external hard drive so you can back up your work without compromising the space on your Mac’s internal hard drive. The same goes for anyone who works with a lot of large files and needs to keep a backup that’s trusted and not in the cloud.
External hard drives are more versatile than you think
Aside from all the above-listed benefits, you can swap out your internal hard drive for your external hard drive. It may sound dodgy but think about it: Chances are, nice, new external hard drives are going to be better than what came with your current computer. Some people put in the nicer, newer external hard drive and use their internal hard drive as their backup plan.
What to consider when buying an external hard drive for Mac
You probably think the number one thing you need to a new external hard drive is space. However, lack of space isn’t such a problem nowadays when it comes to external hard drives as many options have more space on them than your computer itself has. Instead, the number one factor to consider when buying an external hard drive for Mac is reliability.
Consider this: You buy a new hard drive, it looks fresh and has a lot of space, and you’re happy—for two years. And then it fails. Why did it fail?
Because it wasn’t reliable. So, all that data that you backed up, all of those home movies of your kids, everything is just…gone. Poof.
That is why reliability has to be your number one consideration when it comes to choosing the external hard drive of your dreams, but it’s not the only thing to consider.
How fast you can transfer data is also something you’re going to want to think about. Do you want a file that is X gigs in size to take Y amount of time while transferring or do you want it to take double Y amount of time while transferring?
And then, of course, there is the ever-important aesthetic appeal. Some hard disk designs just look better than others. It shouldn’t be your first consideration, but it’s always something to think about when narrowing down your top choices.
How to choose the best external hard drive for Mac for your needs
When choosing the best external hard drive for your needs, consider what your needs are. For instance, when it comes to capacity, are you someone who has a need for the largest capacity hard drive on the market? People who need such great capacity tend to have large video libraries, for instance.
Also, think about how long you want your hard drive to live for. Inferior models may only last a year or so. Hard drive failure is a very real threat and the more issues a hard drive has, the more likely it is to fail. So, if safety and longevity are your primary concern when it comes to hard drives, put that above everything else.
Portability is also something to consider
After all, since external hard drives are only temporarily attached to your Mac, you can take them around with you to places such as to work or school. If portability is a factor in your decision making, go for a hard drive that is designed to be lightweight and portable without compromising integrity, function, and capacity.
And, of course, looks are something to consider. If you’re going to be taking your hard drive to school or something, you probably want it to look nice. Again, that shouldn’t be your primary driving decision factor, but it’s a nice plus if it looks good.

Apple AirPort Time Capsule 3TB Review
Model number: ME182LL/A
Features: Overall the best external hard drive for Mac
This hard drive provides you with up to 3TB (terabytes) of space; this means that it’s got more space on it than a lot of computers on the market today. Therefore, it’d be a great option to backup old computers, so you have access to them after you upgrade.
Easy to use
The Apple Time Capsule is fully compatible with OS X’s Time Machine feature so that all you have to do is plug it in and backing up files suddenly becomes super easy.
The Wi-Fi on the new Apple AirPort Time Capsule is greatly improved over the older model. The Wi-Fi base station comes with 802.11ac technology, and its higher design improves Wi-Fi signal dispersal.
With 802.11ac and apple’s beamforming technology, you’re now transmitting at both 2.4GHz and 5Ghz at the same time with targeted signaling. This allows Time Capsule to select the best band for the device you’re connecting to for ultimate strength, speed, and quality of connectivity.
It’s not just for Macs
Not every household is strictly Mac or strictly PC. More and more families are mixing operating systems in their households. And that’s part of the brilliance with the Time Capsule: It can connect to your PC as well as Wi-Fi devices such as your iPad and Apple TV, among others. No longer do your Mac and PC have to have their separate external hard drives. They can now share, which is very cost-effective, as well as convenient.
The Time Capsule AirPort Extreme Base Station includes three Gigabit Ethernet ports, enabling fast wired connections to other devices.

ConsWhat to consider:
- This version of Time Capsule isn’t compatible with operating systems older than OS X Leopard. However, this isn’t that big of a deal, because Leopard came out in 2007, so many users will have upgraded their devices in the decade since.

- Thanks to the 3-year warranty, you can easily get your product replaced for a perfectly functioning model. This can be an issue no matter which hard drives you choose because factory errors or shipping accidents can damage any computer component, no matter the type or where you buy it from online.
- And, again, it’s important to remember that shipping accidents and the like have no bearing on how the properly functioning model works; this hard drive is very well-liked, after all. This isn’t a con about the product itself, but more of an issue report and how to remedy it.
WD My Book Thunderbolt Duo 4TB External Dual Hard Drive Storage with RAID Review
Model number: WDBUPB0040JSL-NESN
Features: Ideal for video and graphics professionals and hobbyists
Thunderbolt’s bidirectional technology allows for multitasking while doing graphics-intensive projects. While this may not make that much of a difference in the daily lives of those who occasionally touchup personal photos, graphics professionals, and game modders will see a big benefit from Thunderbolt’s multitasking capabilities.
One of the most interesting things about the Thunderbolt Duo is its different operational modes that can be user selected. The RAID 0 setting is a great idea for graphics-intensive work while the RAID 1 setting makes storage safer by making an automatic backup copy of your data. The JBOD (Just a Bunch of Disks) feature allows users to use each drive individually, for the ultimate customized functionality.
The Thunderbolt tech enables bidirectional data transfer channels that can go up to 10GB/s of bandwidth. According to the manufacturer, with this technology, Thunderbolt can transfer a full-length HD movie in 30 seconds. This kind of speed is what makes this hard drive ideal for professionals and hardcore graphics and video hobbyists.
Easy to service
If you manage to fill up the hard disk, all you have to do is take the old one out of the case and put a new one in. It doesn’t get easier than that.

ConsWhat to consider:
- This hard drive is formatted only for Mac, so if you try to run it on Windows, you may get varying results. However, this hard drive was designed to keep in mind those users who run Windows on a Mac device, so it does make accommodations. For more specific questions about whether your setup will work perfectly with the Thunderbolt Duo, contact the manufacturer for more information.
- Copying an entire drive (such as backing up an old hard drive) can take a while. However, this can be a problem with any hard drive you buy. Because the more data you transfer, the longer it will take, and backing up another hard drive is one of the most intensive tasks you can ask an external hard drive to do. Even the best external hard drives for Mac would take a while doing this.
