Ever since computers have hit the consumer market, they have taken the world by storm. Today they are present in almost every household all over the world. As the years passed and technology grew, computers got better and better. Eventually, new operating systems arose but only two prevailed, namely Windows and iOS. While the majority of the consumers opted for Windows desktop machines, the iOS or Mac users have steadily remained extremely loyal due to the exceptional quality and innovation presented by the latter. For decades, the battle between Windows users and Mac users have raged on and there doesn’t seem to be an end to their fight.

A Mac computer is very different from a Windows desktop because it is more surgical in its features and application. It provides features that greatly organizes and enhances the way one can experience working on a computer. Over the years, they have kept on innovating and bringing new features to better streamline a Mac user’s experience.

While in a Windows desktop you can increase storage space by simply adding an additional internal hard drive, you can’t do that with a Mac. Hence, if you need extra storage capacity, you need to get an external hard drive. At the beginning, the capacity of most external hard drives ranged from 120 GB to 250 GB but today the basic ones start with 1 TB at least. Mac and Windows also use different file systems so you can’t just buy any device. Some external drives can be used on Mac but in others, you have to reformat them accordingly.

Best Sturdy External Hard Drive

G-Tech G-Drive ev ATC

This hard drive has a powerful design. What made us put it on our list is its superb resiliency. The ATC which stands for ‘All Terrain Case’. It can withstand half a ton in pressure and can survive a fall from two meters. The water and dust resistant case can also be dunked in water for 30 seconds without the hard drive giving in. In fact with the case on, the hard drive will simply float back up to the surface. It has 1TB of storage and a USB 3.0. If you buy it from the Apple Store, it comes with the Thunderbolt interface so that it can be used with the Macs, but if you intend to buy this online, you will get the ordinary USB 3.0 version.

Best Cheap And Robust External Hard Drive For Mac

ioSafe Solo G3

The G3 is one of the heaviest hard drives that I have come across. It comes with layers and layers of protection to ensure that the hard drive can survive extreme conditions without any problems. When I say extreme conditions I am talking about surviving up to 1550 degrees Fahrenheit for 30 minutes and being submerged in up to 10 feet water for 3 days.

The Solo G3 is a quiet strong device so you will not have to deal with a lot of noise or humming in the background while using this hard drive. But where the company has spent a lot on protecting the hard drive from external damage, there isn’t much that has been done to protect it from internal failure. Meaning, if the Solo G3 fails because of mechanical defects or general wear and tear then there isn’t much that you may be able to do about the data that is lost.

The Bottom Line

In the above list, you can see a wide variety of options available to you as a consumer in the external hard drive market today. Choosing the right hard drive for your Mac requires a number of different key aspects such as ease of use, affordability, durability and functionality. One of the most important factors when looking for an external hard drive for a Mac is durability. Your hard drive is a place where you store all your important data and you do not want it to get wiped away just because it fell down once.

There are a lot of devices on the market today that comes with a low-quality case. Do not by any means purchase them. They might be very cheap, but it won’t be worth it when you lose all your important data in the blink of an eye. Get one that is dust, water and shockproof to ensure the longevity of your device. They won’t be able to protect your data from a two storey fall but they can sufficiently save your files in cases of small drops. Most of the durable ones offer protection for drops up to 1.2 m.

The next crucial factor you need to look for is functionality which includes features. It would be wiser to go for an external hard drive that has password protection so you can get both external as well as internal security for your files. Last but not the least is the cost of the device. Some offer tons of cool features but are expensive whereas others offer fewer features for a lower cost. With a little bit of research online, you can find the right storage device for you in no time at all.

Anyone who uses a PC should have an external drive. It’s not only a useful means of data backup and storage, it also allows you to transport files from your desktop or laptop to another device.

Xbox One X users, as well, would be wise to invest in an external drive as a way of augmenting the console’s measly 1TB hard drive (the external drive needs to be USB 3.0-compatible and will be formatted when you insert the drive).

The best external drives 2019

  • WD My Passport 4TB: Best external backup drive [amazon.com]
  • Samsung T5 SSD: Best external performance drive [amazon.com]
  • Samsung Portable SSD X5: Best portable Thunderbolt 3 drive [samsung.com]

The question is, which external drive is right for you? To answer that, we’ve combed through our reviews of both external hard disks and SSDs to pick the top drives we’ve tested. We’ll also walk you through what you need to know to buy the best external drive for your needs.

Updated March 27, 2019 to add two reviews that put style on an equal footing with performance.

  • The G-Technology G-Drive mobile USB-C external drive (available on Amazon) performs well, and G-Technology always delivers attractive designs that seem intended to harmonize with Apple products. Alas, along with the Apple design cues, comes an relatively Apple-like price. Read our full review.
  • The Seagate Backup Plus Ultra Touch (available on Amazon) is a svelte drive that sports an attractive basket-weave polyester fabric, as well as good benchmark results. The price is pretty affordable, too. Read our full review.

Best external backup drive

Lots of storage for less than the competition, attractive styling, and good performance with small files highlight this USB 3.0 portable hard drive. An excellent bargain.

Our pick for best portable external backup drive for 2017 is Western Digital’s My Passport 4TB drive. Although it’s a tick or two slower than other backup drives (like our runner-up, for example) in sequential file writing (think copying movie files), it does better at writing small files (think hundreds of Word or Excel documents.) It’s not flashy or super-fast, but for most people who only whip it out once a month to run backups and then shove it back into a drawer, those things don’t matter as much as the capacity, price, and reasonable performance. (Read our full review.)

Runner-up

If capacity and portability are your primary concerns, and the Backup Plus Portable fits up to 5TB in pretty much a standard 2.5-inch USB external package. It's fast with large files, but on the slow side with small ones. Regardless, it's a worthy drive that gives you more space for your movies and games.

Our runner-up for this popular category is Seagate’s slightly larger and somewhat faster Backup Plus Portable. Like the WD above, it’s a USB 3.1 Gen 1 (5Gbps) drive. It tops out at 5TB in a single drive and can also be had in 1TB, 2TB, and 4TB capacities. There’s even a “fast” 4TB version that uses two hard drives in RAID for more performance.

In our tests of the 4TB version, we found the Seagate to be slightly faster with large file transfers (think movies) but worse with small file transfers (think Office documents). It’s still a worthy runner-up, though. (Read our full review.)

Best performance USB drive

The T5 is easily the fastest non-RAID portable USB SSD we've tested. It makes full use of its Gen 2, 3.1 interface while retaining the svelte profile of the T3. A winner for sure.

Remember that scene in Office Space where Peter Gibbons is desperately trying to save files to disk before getting out of the office? Yeah, mmkay. If you need ultra-fast performance in a package that you can put in your pocket, look no further than Samsung’s new T5 . Not much larger than a book of matches, the T5 comes in sizes from 500GB to 2TB. The best part is its speed. The drive features a USB 3.1 Gen 2 (10Gbps) over USB Type C.

And no, unlike most USB “thumb drives” this baby doesn’t hit the wall when writing files. It can write 20GB of files in just 110 seconds. If it’s a single large file, it’ll write it in 58 seconds. (Read our full review.)

The Extreme Portable SSD's convenient form factor trumps the drive's slight performance deficit compared to the Samsung T5. With its fast USB 3.1 Gen 2 (10Gbps) capability, this is currently our favorite portable SSD.

Runner-up

The new drive here is the runner-up, which some may consider an even better pick than the Samsung T5: The Sandisk Extreme Portable. You can read our review of it here, where we give it 4.5 stars and an Editor’s Choice Award. It’s a seriously fast USB 3.1 Gen 2 (10Gbps) drive, just not quite as fast as the Samsung T5.

You might still choose it instead of the Samsung T5 because it’s more comfortable with its rubberized grip finish. It comes with a nifty combo cable that adapts to old-school square USB Type A and also works with USB-C ports.

The Sandisk Extreme Portable displaces the Sandisk Extreme 900 drive, but we think it’s a fair decision because the Extreme 900 is, well, pricey. At $700 for 1.92TB, it’s hard to justify over the Extreme Portable’s $521 for 2TB.

Best portable Thunderbolt 3 drive

Portable Thunderbolt 3 drives have been long overdue, but we’re happy to recommend Samsung’s new Portable SSD X5 drive. The full review is on our sister site Macworld, but let’s just say it’s stupidly fast and kinda like putting a scorching Samsung 970 Pro in an enclosure that fits in your pocket and not giving up much performance at all.

Notice that we don’t say “best portable performance Thunderbolt 3 drive,” because by very definition, a Thunderbolt 3 drive should be blazingly fast. The only reason we’re not universally recommending the Portable SSD X5 is the relative rarity of Thunderbolt 3 ports on PCs. You’d need to be driving a brand-new Dell XPS 13 or HP Spectre x360 13 to be able to use Thunderbolt 3.

What you need to know before you buy

Best External Solid State Drives Reviews

Capacity and price

External-drive shopping can pull you deep into specs and features, but the most important two numbers for consumers are capacity and price. Many assume the lowest-cost drive gets you the most value, but it often doesn’t. In fact, dollar for dollar, it’s often the worst deal.

For example, we took the WD Black My Passport portable drive and compared the prices of the 1TB, 2TB, 3TB, and 4TB drive, on capacity and price. Keep in mind, this is one drive on one day (July 11, 2017), and just one vendor, Amazon, but it illustrates the point.

If you look at the chart above, you can see the worst deal is that $58 1TB HDD, while the 4TB nets the most storage capacity for the money. Here are the same numbers in a bar chart form:

So yes, if you’re buying an external drive, you pay more for the lowest capacity. However, this doesn’t mean you should automatically shell out for that 4TB drive. In the end, it still costs more. If you really don’t need the storage capacity of a 4TB drive, put that extra $57 toward something you actually do need.

Interface

The vast majority of drives today are USB drives. From there it gets confusing. Today, the flavors include: USB 3.0, USB SuperSpeed, USB 3.1 Gen 1 (which is basically USB 3.0), and USB 3.1 Gen 2.

For the most part, it doesn’t matter which of these versions you get (beware the much older USB 2.0, though). USB 3.0 allows transfer speeds up to 5Gbps, as does USB 3.1 Gen 1. USB 3.1 Gen 2 is the fastest USB version and can move data up to 10Gbps. No single hard drive today can surpass the throughput of USB 3.1 Gen 1, though. The sleight of hand to watch for is if a drive vendor lists “USB 3.1” in the specs without specifying Gen 1 or Gen 2.

The only place Gen 2 can help is with an SSD. The good news is that while USB 3.1 Gen 2 used to be only in crazy expensive SSD external drives, it’s fairly affordable today. A Sandisk Extreme Portable SSD that is our runner up for portable storage can be had for $125 in a 500GB capacity.

Ports

External drives come with a variety of confusing and esoteric ports. Here’s what you need to care about.

USB 3.0 Micro B port is the most common port on portable backup drives today. It’s basically the same Micro USB port used on your phone, but beefed up with more connectors to hit USB 3.0 speeds. It’ll hit 5Gbps and for everything but the fastest portable SSDs is still fine.

Reviews - Best External Solid State Hard Drive

USB 3.0 Type B port is the larger, blocky version of USB 3.0 Micro B. USB 3.0 Type B is often used in larger external drive enclosures. As its name implies, it’ll hit USB 3.0 speeds at up to 5Gbps.

USB Type C is the newest of the USB connectors and features a nifty reversible design that’s being used on phones, tablets, and PCs. Its most important feature is that it supports up to 10Gbps transfer speeds. The key phrase here is “up to.” USB Type C is just the connector and port on the drive (or phone), but the rules allow USB Type C to support transfer speeds from USB 2.0’s 480Mbps to USB 3.0’s 5Gbps and USB 3.1’s 10Gbps. So don’t caught up thinking that because a drive you buy has this nifty new interface and port, you’ll get awesome speeds. And no, hooking up a hard drive to a USB Type C port doesn’t make anything faster.

Outside the theoretical speed advantage of USB Type C is a power advantage. A standard USB Type C port on your desktop or laptop should be able to support a minimum of 15 watts, so you should be able to run larger, more power-hungry drives.

Thunderbolt 3 was designed as one cable to rule them all, and it’s rapidly looking like it will. The port basically adopts a USB Type C port and connector but also offers the ability to run pure PCIe at up to 40Gbps. For the performance-minded, Thunderbolt 3 is the natural alternative. One negative, though: It ain’t cheap. Our recommended portable, the Samsung Portable SSD X5 is $697 for 1TB of capacity. A 1TB Samsung T5 on USB is only $278.

There’s no reason to pay extra for a Thunderbolt 3 drive unless it’s high-performance. A Thunderbolt 3 portable hard drive would be a complete waste of time and money for most people.

Best External Solid State

Thunderbolt 2 is, at this point, a dying port. Using a miniDisplayPort connector, it only really gained popularity on Macintosh PCs and is now being put out to pasture. Unless you have an older Mac, there’s really no need to invest in a pricier Thunderbolt 2 drive or port today unless it’s for legacy support issues.

eSATA is another mostly dead port. Made as an extension of SATA, eSATA was a cheap way to get beyond the 60MBps performance of USB 2.0. USB 3.0 put the last nail in its coffin, though, so you can ignore this port today. Like Thunderbolt 2, the only reason to invest in an eSATA drive is for use with older computers.

Buy two?

There’s an old saying that “one is none and two is one.” You can apply that phrase to space capsule oxygen tanks, plane engines, or whatever mission critical system you depend on, including hard drives.

The philosophy on external drives used for backup is that copying 10 years’ worth of photos onto an external drive and then erasing it on your PC’s local drive isn’t actually a backup at all. If that drive gets chewed up by the dog or otherwise dies, you’ve lost it all.

If you’re paranoid about backups, consider getting two backup drives, possibly in different colors, and then alternating complete backups of your PC to the drives every few month. This should mitigate data loss should a drive die. Truly paranoid people will even take the second drive to work so there’s no chance of losing both drives to the same local disaster.

How we tested

Best External Solid State Drive For Mac

We use our standard storage test bed to evaluate the performance of the drives we review. It’s an Intel six-core Core i7-5820K on an Asus X99 Deluxe motherboard with a Thunderbolt 3 card and 32GB of RAM running Windows 8.1. We use various synthetic benchmarks including Crystal Disk Mark 5, AS SSD, and Iometer. We also use a manual file-copy test where 20GB of small files and another 20GB single file are written to and read from the storage drive. The test bed boots to a plain SATA drive, but all targets and sources for drive performance use a 24GB RAM disk.

We also use an Asus Thunder EX3 discrete Thunderbolt 3 card and Asus USB 3.1 10Gbps card for testing. The Asus card uses an Asmedia 1142 controller.
