Tom Brant The Best External Hard Drives for Mac Looking to add storage, or for a smart way to back up your Mac? Here's what you need to know, along with our top-rated Apple-friendly drives. We've tested SSDs and platter-based drives alike.
The Right Connections Buying an external hard drive for your Mac is not all that different from buying one for your Windows PC, except for one very important complication: Newer and only come with Thunderbolt 3 ports, but the arrival of Thunderbolt 3-equipped drives has been a trickle, rather than a flood. Most of the current models are designed for photographers and video editors who need to store mountains of footage and access it very quickly. As a result, they are typically SSDs or arrays, which means they're also very expensive. So what's a Mac user who just wants to back up his or her files using Time Machine to do? Read on as we answer that question, and solve your other Mac external-storage quandaries. A New File System Thunderbolt 3 and USB Type-C are the latest innovations in the external storage market, but before we get to them, we need to address a basic building block of hard drives that has always affected compatibility, and probably always will: the file system. An external drive's file system is the most important factor that determines whether or not it's readable by Macs, PCs, or both.
Since the late 1990s, Apple has used the Mac OS Extended file system, commonly abbreviated as HFS+, to power its laptop and desktop computers. But with the release of the operating system, Cupertino switched to an entirely new file format. It's simply called the, and it's the first format to be used on Apple computers as well as the iOS ecosystem of, iPods, the Apple TV, and the Apple Watch. There are many benefits to switching from HFS+ to the Apple File System, including better security thanks to native encryption, but the most important thing to note for external drive shoppers is backward-compatibility. Any drive formatted with HFS+ (which includes most Mac-specific drives on the market today) will work just fine with a Mac that's running macOS High Sierra.
Neither Apple File System nor HFS+ works with Windows, however. If you plan to use your external drive with computers that run both operating systems, you should consider a drive formatted with the exFAT file system. Microsoft introduced exFAT about a decade ago, which means that it's still relatively young, as far as file systems go. You won't get the security and efficiency of Apple File System, but you will get the convenience of being able to transfer files back and forth between Windows and macOS simply by plugging in and unplugging your drive. Of course, you can easily reformat almost any drive you buy, so you're not limited to buying only those intended for use with Macs. If you really fancy a drive formatted for Windows (which will usually come preformatted in the NTFS format), you can use the Disk Utility in macOS to reformat it after you bring it home from the store. There are a few exceptions to this rule, but they're rare.

The only drive we've tested recently that isn't Mac-compatible even if it's formatted is the pro-oriented, which uses a lightning-quick Intel SSD inside. It relies on firmware that requires motherboard-level support that isn't found in any Macs. SSD Versus Spinning Drive Once you've settled on a file system, you then have to determine which storage medium you want:. Each has its advantages and disadvantages, and—unlike the file system—the type you buy is the type you're stuck with for the life of the drive. A solid-state drive (SSD) offers quick access to your data because it stores your bits in a type of flash memory rather than on spinning platters. SSDs are often smaller and lighter than spinning external drives, as well, which is also thanks to the lack of moving parts.
Their small size means they can often fit into a jacket or pants pocket, which makes them a better choice if you're looking for a portable external drive that you'll be carrying with you frequently. One major downside, however, is that they're much more expensive. You could pay more than 30 cents per gigabyte for an SSD, while spinning drives can be had for less than 10 cents per gigabyte—and often much less. External SSDs also have much less capacity, with most drives topping out at 2TB. Compare that with spinning drives; portable hard drives top out at 5TB, and desktop ones are easy to find in capacities in excess of 8TB.
For professional videographers who edit lots of footage and gamers or movie buffs who have large libraries of multi-gigabyte titles, an external RAID array is worth considering, since it combines the speed of an SSD with the gargantuan capacities of a spinning drive. An array typically contains as few as two or as many as eight spinning drives, which all work together to speed up throughput, or guard your precious files against corruption via drive redundancy if one of the drives fail. (Or both; it depends on how the array is set up.) The result is that you can get SSD-like speeds, with data throughput of more than 400MBps, and capacities that top out close to 50TB. You'll pay handsomely, of course.
The Mac-specific, for one, can cost as much as $5,000. On the other hand, if you're looking to buy an external drive mainly to back up your files and it will rarely leave your home office, an inexpensive spinning drive will work just fine. Searching for Thunderbolt 3. So, to recap: Faster, smaller (both physically and in terms of gigabytes) solid-state drives come at a premium, while spinning drives offer a much better value while sacrificing speed. But what happens when you throw yet another variable into the mix: the connection between your drive and your Mac? As you might have guessed, the answer is more tradeoffs. Every Mac laptop sold today comes with ports that support Thunderbolt 3, but other than a headphone jack, they are the only connectivity options available, which means you'll need an adapter to plug in any device that doesn't have a USB Type-C cable.
Fortunately, Thunderbolt 3 via USB Type-C supports a blazing maximum potential throughput of 40Gbps, double the speed of the old Thunderbolt 2 standard and many times the 5GBps that USB 3.0 offers. Unfortunately, you won't find many Thunderbolt 3-compatible drives on the market currently.
Even some Mac-specific drives are still sold with USB 3.0 connectors. Moreover, the Thunderbolt 3 drives you can buy are constrained by the maximum throughput of the drive itself, rather than the Thunderbolt 3 interface. The speediest SSDs we've tested recently top out at around 600MBps, for instance. This means that for now, it's best to include Thunderbolt 3 support in your buying decision only if you're concerned about futureproofing. While it's nice of manufacturers to include a USB Type-C cable for people who own a USB Type-C-only MacBook, you can pick up a converter for a few dollars online if the drive you're eyeing doesn't offer one. Meanwhile, iMacs, Mac Pros, and Mac Minis all still come with USB 3.0 ports, so they won't require adapters, for now.

Other Considerations Drives intended for PCs sometimes come bundled with software that will automatically back up your files to the drive when it's connected, but such software isn't really a consideration for Mac users, who already have an excellent built-in backup option in the form of Time Machine. The first time you plug in an external drive, Time Machine will ask if you want to use it as a backup drive. While you can customize backup options in System Preferences, such as asking Time Machine to exclude certain folders, there's no action required on your part if you're happy with the default settings. The next time you plug in your drive, Time Machine will automatically set to work creating a backup. Unless your drive is never going to leave your home or office, you should also consider its physical durability. Rugged, waterproof drives are a good option not just for surfers and BMX riders, as their marketing seems to suggest, but also for people who are carrying their drives to and from school or work, where they might occasionally get spilled on or dropped on the floor.
(Check out.) Finally, you might want to consider how the drive will look when it's plugged into your Mac. Some drives, like the WD My Book, come in a variety of colors. Many others feature copious amounts of aluminum and industrial-chic styling to match the design cues of your MacBook or iMac. Ready for Our Recommendations?

Looking for a way to install and run OS X on an external hard drive? This can be useful for a couple of different reasons. Firstly, it allows you to run another copy of OS X without needing any additional Mac computer. Also, since you can run a full copy of OS X on the external drive, it can be used for troubleshooting purposes on other Macs or it can be as a kind of virtual OS X. I’ve already written about how you can, but that takes up space on your Mac. Using an external drive, you can save space on your Mac, though it might be a bit slower if you are using USB 2.0.
In this article, I’ll walk you through the requirements and steps to install OS X onto an external hard drive. Format External Hard Disk The first thing you’re going to need to do is format the external hard drive properly. The file format has to be Mac OS X Journaled and you have to use the GUID partition map.
To do this, open Disk Utility and connect the drive to your Mac. Under External in the left hand menu, click on your external hard drive and then click on the Erase button.
Make sure you backup any data before you erase the drive. When you click Erase, a dialog will pop up where you can configure some options.
Give your drive a name, choose OS X Extended (Journaled) for Format and GUID Partition Map for Scheme. It should only take a minute or two for the drive to be erased and reformatted. Now your drive is ready for OS X. Install OS X There are two ways you can install OS X on to your external hard disk: by reinstalling OS X from the OS X Utilities repair screen or by downloading OS X from the App Store and running the installer. I’ll show you both methods in case one isn’t working for you.
The easiest way is to download OS X from the App Store. Once you open the App Store, you’ll see a link on the right for the latest version of OS X (El Capitan as of this writing).
Go ahead and click the Download button to start downloading the installer. Note that if you already have that version of OS X installed, you’ll see a popup message appear asking if you still want to continue or not. Just click Continue.
Once it has been downloaded, just double-click the installer, which will be located in the Applications folder. Keep clicking past the license agreement, etc., until you get to the screen that asks you which disk to install OS X on. By default, it is set to MacBook. Click on the Show All Disks button and you’ll see an icon for the different disks and partitions on the Mac. I named my external hard drive OS X and that shows up in the middle.
You can also tell it’s an external hard disk because it uses the icon with the orange hard drive. Click Continue and then follow the instructions to complete the installation. Note that your computer may restart during the install and you don’t have to do anything.
OS X will automatically continue installing onto the external hard drive rather than booting up to your internal version of OS X. At the end of this article, I’ll show you how to boot up to the external hard drive, so skip down if you ended up using the App Store method. Note that by default, the Mac will start booting up directly to the external hard drive until you change it. The second method to install OS X is to restart the Mac and press and hold the COMMAND + R keys. This will load up OS X Recovery.
The OS X Utilities screen will appear and here you want to click on Reinstall OS X. Again, you’ll go through some basic screens, but when you get to the hard disk screen, click on Show All Disks again. Using this method, you’ll have to login using your Apple ID and password so that the entire OS X installer can be downloaded off of Apple’s servers. Whichever method you choose, it will take anywhere from 15 to 30+ minutes to install OS X onto your external hard drive. While OS X is installing, your computer will restart a couple of times. Note that when it finally boots into OS X, that is the version running off your external drive.
To switch back and forth between the internal and external drive, you have to restart your computer and hold down the OPTION key. When you do that, you should see at least four icons. In my case, I have five because I have Windows installed using Boot Camp. Anyway, the grey MacBook and Recovery 10.11.2 icons are for my internal OS X and the orange OS X and Recovery 10.11.3 are for the version installed on my external drive. Use the arrow keys to select which drive to boot from and then simply press Enter. If you have a newer Mac and a USB drive that supports USB 3.0, everything should run fairly fast.
Overall, it’s a fairly straight-forward process and took me less than an hour to get everything working. If you have any questions, feel free to comment.
