Tip # 1. Decide between SSD and HDD

External storage solutions come in these 2 varieties. SSD (solid state drives) are like big USB flash drives with multiple memory chips to store data, whereas HDDs are rotating magnetic disks. If you need more room to store gigabytes of data (videos or photos), you should consider getting an HDD. If your purpose is to get more memory for your Mac’s operating system and apps, then an SSD would be just the right option.

SSD: more speedy, more resistant to shocks, thinner (lighter)
HDD: slower, louder, offer more capacity, cheaper (per 1 GB of storage)
To make your choice even trickier, there also hybrid drives. These are regular HDDs with an SSD memory block attached, so you get the best of both worlds — speed and capacity within one device. At this point, think why do you need an external hard drive for your Mac in the first place: if it’s for backup and storing the sensitive data, simply go with an HDD.

Tip # 2. Free up space on your existing drive

Before getting an external Mac storage device, plow through the garbage on your existing one. This might save you dozens of gigabytes worth of data. For the most part, it’s old downloads, large media files (and their duplicates), application cache, old iOS backups and, finally, old apps you never use.

In my experience, the best cleanup results are achieved with a dedicated app. I was skeptical about Mac cleaning apps until I came across CleanMyMac X, as it’s the easiest of all. And really does the job as advertised. My first scan got me around 50 GB back under wrongly deleted volume — I was wondering where my disk space was going!

Tip # 3. Consider getting a NAS external hard-drive for Mac


There are lots of alternatives even within the HDD domain. If you need to process anything over 2 TB of storage, consider a NAS drive. Network-Attached-Storage (NAS) is a shared storage connected to your network router that everyone within your network can access. It’s a good solution for manipulating large size data, like your media backups.
How do they work? NAS boxes are connected to your router via an Ethernet cable. It’s worth mentioning, that some NAS drives are Mac-friendly and pre-configured to store Mac’s native Time Machine backups. This comes handy to free your macOS from extra copies of itself.

Apple’s Airport Time Capsule (though now discontinued by Apple) is a pretty expensive NAS solution, basically, a WI-FI router and NAS drive in one body. What’s good about it is its native integration with Mac, which makes the messy backup business at least partly human. It can even backup from with multiple Mac hard drives within your network.

Tip # 4. Read about RAID drives before buying HDD for Mac

Having to choose external hard drive for Mac, take a minute to learn about RAID drives. RAID are multiple hard drives that can be combined in one set. If combined properly, 2 hard drives may double write and read speeds because the data gets split between the two. Variations of RAIDs (RAID0, RAID5 etc) specify how exactly the data is split between your Mac external hard drive.

One more use is protection against data loss. Should one drive fail for some reason, the data will be duplicated on a second one. Also, the space issue. 2 hard disks will store 2 times more data, so from your Mac’s perspective, it will look like one single HDD twice as capacious.

Should you bother with RAID when choosing best external hard drive for Mac? Probably not, unless you’re using a ton of data and a quick data extraction is critical to you. For individual use, standard HDD will do just fine.

Tip # 5. Study the failure rate of your external drive

Each manufacturer claims their HDD is the most reliable but the fact is, some hard drives fail more often than others. AFR (annual failure rate) is a scientific method to prove that. According to Google, annual failure rate is 8% for drives after 2 years in service. In other words, one out of 12 drives will fail. Here is a chart by Backblaze that should give you an idea which team wins in the reliability tournament. As you can see, even for one manufacturer the failure rate varies from model to model.

Tip # 6. Choose your preferable speed

It’s not as if it’s Formula One case, but HDD spindle speed issue is pretty vital. There 4 standard options: 5400, 7200, 10000, 15000 rpm. If you make music or videos on your Mac, you might go for the best speed available on the market which is 10.000 — to 15.000 rpm. Though, the faster an external drive for Mac is, the less capacity it offers.

Tip # 7. Buy an HDD that sports USB 3.0 (or better)

Your external Mac hard drive will have many connection options. Anything lower than USB 3.0 is already outdated nowadays, so it should be your minimal starting point. Thunderbolt 3 or USB Type-C is the fastest port on Mac. It’s advertised as being able to copy 14 hours of HD video in less than a minute. So make sure your portable hard-drive for Mac is Thunderbolt-3 compatible.

Tip # 8. Consider portability

Depending on their physical size there are several external drive options. We assume you are not a company and don’t need the large enterprise-class drive (used for running servers). This means you’ll likely be choosing between standard desktop-class drive (with spinning platters) and slimmer SSD options, more resembling USB drives.
Standard desktop drives offer capacities of around 8 TB which should be perfect to store your movies and photos collection. These desktop-class external hard drives for Mac rely on wall power supply and they lack portability. Portable hard drives for Mac, on the other hand, are powered by your computer and can be surprisingly tiny nowadays. Here’s the golden formula to keep in mind: considering capacity, size and cheap price, be prepared that you can’t have all 3 at the same time. Want your drive to be very small and very capacious? Then, there’s no way it can be cheap. And likewise, if you aim at a cheap and capacious drive, it can’t possibly be small in size — you get the idea.

Not only is the Western Digital Elements 2TB Hard Drive fast, it also offers a hefty 2TB of storage, which should be plenty for most people's needs.While much of the world is moving toward cloud storage, a great external hard drive can still be an extremely helpful tool, especially if your internet connection is spotty or you simply want to move files around without having to rely on cloud storage.Of course, there are a ton of external hard drives to choose from, and they’re not all equal. A lot of work and development has gone into building on storage technology over the last few years, and as such, they’ve gotten a lot better.There are a few things to keep in mind when you’re in the market for a new portable hard drive. For starters, you’ll want to consider the type of hard drive you want.HHD vs. SSD: There are two main types: HHDs, or hard disk drives, and SSDs, or solid-state drives. The difference is pretty important. HHDs store information on a spinning disk and that disk can be a source of hard drive failure. SSDs, on the other hand, have no moving parts and are thus more reliable as portable hard drives. The tradeoff is that SSDs are a lot more expensive.Storage amount: You’ll also want to consider how much storage you need. If you’re a videographer or photographer, chances are you could easily fill up a hard drive quickly, so you’ll want a higher-capacity drive. If on the other hand, you’re simply transferring Microsoft Word documents to and from work, then you won’t need as much storage and could save a few bucks by getting a lower storage drive.Connection: Next up, you’ll want to think about the kind of connection you want your hard drive to connect through. The vast majority of external hard drives connect to a computer through USB, and nowadays it’s through USB 3.0, but there are still some USB 2.0-capable hard drives. There are also plenty of hard drives that connect through Firewire, and some that even connect through Thunderbolt.Operating system: Last but not least is operating system-compatibility. Now, most hard drives can be formatted to work with both macOS and Windows, and you’ll be able to set that up when you first get the hard drive. Some, however, are pre-formatted, so you don’t have to worry about formatting.Make two copies in different locations: A quick note about hard drives: none of these are 100% reliable. You should always have two copies of your data in different locations.
