The Best External Hard Drives of 2020
We can't gush enough about how impressed we are with the Samsung Portable SSD. Its lightweight design (1.75 ounces) fits into the palm of your hand and doesn't take up much space inside your laptop backpack or purse. It features an AES 265-bit encryption with password protection, a metal housing, all that is drop-resistant up to two meters (and yes, we tested this). Read and write speeds are incredible! While the manufacturer claims a speed up to 540 MB/S, we clocked it going up to 506 MB/S (Blackmagic Speed Test, MacOS) and 462 MB/S (CrystalMark Test, Windows). Our drag and drop tests show an even lower speed (actual speed), averaging 237 MB/S when moving files 2, 6, 10, 100 GB in size. Overall, it proves to be 3X faster compared to other external hard drives tested in all our tests. Plus, it comes in super-nifty colors, suited for anybody's style.
While we never like to say any product demonstrates complete perfection, this one comes pretty close. There are no negative online reviews that we've found, with the exception that you need to watch out for fake or knock-off products. The price is a bit high, costing about five cents per GB (calculated with 500MB storage), but gets better as you move up the storage scale. Aside from that, it can get a little warm when running for a long period of time, and the smaller size means it can be misplaced easier than larger drives.
Armored in a protective shell, the Adata Durable Hard Drive is an HDD (Hard Disk Drive) built to take the biggest of beatings. We immersed it in water for two hours, drove over it with a half-ton truck, and dropped it six feet onto concrete. In all cases, it came roaring back to life, with all data stored intact, working seamlessly. No other hard drive could take this kind of abuse, making it our favorite rugged hard drive. It comes set-up for both Mac and Windows platforms and is compatible with both PS4 and Xbox gaming systems. If you want a reliable and armored external hard drive, this is it. Throw it in the sand, accidentally drop it in the water; your data will still be protected. It's an excellent value that works out to roughly five cents per GB (based on 2TB storage).
While intrepid durability is its stand-out feature, it has its drawbacks. First, it's far from the fastest performing. During our drag and drop tests, it averaged 64 MB/S when moving different sizes of files. During optimized testing (where we see the highest possible speeds), it clocked read and write times of 119 and 116 MB/S respectively for macOS systems. For Windows, the fastest time recorded is 135 MB/S (read) & 127 (write) using the USB-A port. Expect this drive to be slower than other top performers. It's also bulky and heavy but still fits nicely into the pocket of any backpack.
The WD Black GameDrive is a favorite amongst gamers for its compatibility with multiple platforms, and fast read/write speeds. As games get larger in size, the need for additional storage is becoming paramount. This external hard drive features a durable exterior that will survive a six foot drop on both carpet and concrete. It's the fastest when used with PC computers and windows platforms. We clocked its read and write times at 237 and 128 MB/S, respectively, using a Windows platform. On our Mac, it only clocked a speed of 121 and 118 MB/S (read and write respectively), proving it is fastest with PCs. What's more, the random read/write tests are higher than other product, meaning that it'll perform seamlessly when running games or movies directly off the drive. We also like the 'gamer-focused' look. At a cost of only two cents per GB (2TB option), you can't go wrong with this top seller.
While it does offer great performance, many online users are not fans of the soft humming that the internal disk emits during play. Also, during our 'actual drag and drop tests,' the speed of the drive decreased to 68 MB/S with slower performance as file size increases.
The LaCie Rugged Raid Shuttle stands out for its rugged design and super-fast processing speeds. This HDD is wrapped in a shock-proof package that'll withstand drops from 1.2 meters. We even drove over it with our Subaru Outback, and it survived! It has the potential for very fast processing speeds (clocked at 272 MB/S), including a high random read/write speed, which means it can quickly access data even with a large pool of information. That said, during our drag and drop tests, it averaged 81 MB/s, putting it in the top tier for fast actual speeds. It features an encrypted security system with different levels of security. While the sticker price might seem high, it works out to about six cents per GB, which is a good value.
To be honest, we were excited to test all the claims made by LaCie and its durability and see success, but we are let down. Out of the package, the USB-C to USB-C cord kept disconnecting the drive when plugged in. It is supposed to be rated to IP54 for water, meaning that it can withstand a stream of water from any direction. However, when we sprayed it with the hose, it never worked again, failing our test. This is most probably because of the exposed USB-C port, which is a fatal design flaw for this 'rugged' and 'water-resistant' drive. Furthermore, data transfer speeds decreased by almost 85% when the drive wasn't plugged into its external power source. Be aware of potential durability issues and false company claims with this product.
If you're seeking a lightweight but durable Hard Disk Drive (HDD), the Silicon Power Rugged drive is our pick. Most HDDs are bulky and heavy, but this one slides easily into small pockets and purses. It features an average read and write speed, and works with multiple systems. The durable exterior is wrapped in Silicon while the hard drive is suspended inside to make it drop and even water-resistant. While you can't immerse this drive in water, if you accidentally spill a glass of water on it, it'll survive. We dropped it from six feet on both carpet and concrete, and it still performed flawlessly. If a durable, lightweight HDD is what you seek, you've got to check this lightweight contender out. It costs about four cents per GB, which is a good value (based off 2TB drive).
Unfortunately, while the optimized tests on both Mac and Windows show read and write speeds to be about average, this drive proves to be one of the slowest in our actual drag and drop tests. When dropping files of different sizes (2, 6, 10, 100 GB) on a macOS disk to the drive, it averages about 62 MB/S (lowest of all drives tested). The speeds seriously decreased with an increase in file size, slowing to snail's pace during the 100 GB drop to 32.6 MB/S. In addition, the cord that comes with the drive is poorly anchored to the drive and is quite easy to lose. Aside from these caveats, it's a functional and durable drive that works for most uses.
The Toshiba Canvio Basics 2TB is a standard SDD that offers benchmark reliability, storage, and speed. Its lightweight and portable design seems more durable than other options in its price category, and the two cents per GB price is hard to beat. It doesn't have any super fancy features but proves to be a little durable, surviving a five ft drop test on both carpet and concrete. Its read and write times are sufficient for data back up and storage, but not the fastest that you'll see out there. If you're in the market for a high value, simple, and affordable hard drive, this is Best Buy award winner is a great choice.
While the timed speed tests reflect speeds in "optimized conditions," we learned this drive transfers data at a rate of 66 MB/s during our drag and drop tests, significantly decreasing read and write speeds with larger files. For example; when dropping a 100GB file, it read at a rate of 30MB/s while a 2GB file offered a speed of 90MB/s. These speeds are about average for this price point. Also, there are no data recovery services should the drive fail, nor are there any included security features.
The Seagate Portable 2TB is another low priced and lightweight SSD with easy plug and play capabilities. There are many storage options, and it's pretty inexpensive, costing only two cents per GB. It doesn't boast any fancy features or come with any additional software. Simply plug it in, and start uploading your games, pictures, or files. If you're a gamer, you're in luck as its compatible with both Xbox and PS4. Many online users verify that you can play the hard drive right into your system. Overall, we appreciate this drive's high value and versatility across all platforms.
Unfortunately, the low price is a reflection of its slower read and write speeds on both Mac and PC platforms. While we clocked its max read and write speed at 160 and 124 MB/s respectively (PC, Windows, USB-A port) in optimized conditions, its speed decreases significantly during actual tests. It tied for the last place, moving along at just 62 MB/s. Speeds also declined significantly with file size. File sizes ranging from 2 to 10 GB averaged around 70 MB/s while the 100GB drop took almost 45 minutes, with a measly speed of 40 MB/S. Overall, don't believe the speed claims that Seagate advertises. However, if you're looking for a simple, inexpensive drive that doesn't need to be the fastest, this high-value contender will do the trick.
If you're seeking a backup for your desktop that'll update automatically, the WB My Book Desktop 3.0 3TB should be on your radar. It features consistent read and write speeds, a performance feature you'll be hard-pressed to find in the external hard drive world. Optimal speeds occurred using PC computers (Windows platform) at 210 MB/s. Actual speed tests averaged 148 MB/s, the second-fastest in this review. What's more, these speeds stayed pretty consistent across all file sizes, and didn't slow down with larger files. In terms of cost, it'll cost , only three cents per GB (based on the 2TB drive we tested). Another cool finding is it has some drop resistance despite its large and seemingly fragile design. We dropped it (cringing the whole time) on both carpeted and hard surfaces from waist height, and it lived! This impressed us as it's not rated to withstand these tests.
This drive is not meant to travel. It scratches easily and is heavy. It requires an additional power source to use, so it's the best living attached to your desktop. While we didn't test water resistance (it's not rated to deal with water), we imagine it wouldn't survive because the case is littered with lots of holes for proper ventilation, which leads directly to the hard drive inside.
We were intrigued by the security features and seemingly durable design of the Buffalo Mini Station Extreme NFC 2TB. It boasts 256-bit AES Full Data Encryption with passcard/password access, and is one of the most secure drives we've tested so far. The rugged design has us intrigued by its alleged IPX3 water and IP5X dust protection. We clocked read and write speeds at 135 and 128 MB/s, respectively, during optimal conditions. During our actual drag and drop speed tests, it averages 77 MB/s, performing at about an average rate amongst all hard drives tested. At first glance, and with just a few day's use, we were sure this would be an award winner. The construction seems solid, while the security is impressive. It costs about four cents per GB.
However, during our first durability test, this external hard drive stopped operating. The drop test was performed first at a waist-high drop on a carpeted surface, then tested on the computer to see if it still worked. After just this first test, the drive failed to work. Every other drive passed this test. This is an upset, especially with its alleged mil-spec shock protection. When looking online, we didn't find any other issues like this, so it's possible this defect lays with this specific hard drive. However, it is still a disappointment and an experience worth mentioning. Another caveat is set-up takes research. Initially, when reformatting for use with a Mac, many of the security features didn't come up. We had to actually set up security on the PC platform, which then transferred when using the Mac. Had it survived our drop tests, this external drive would easily be an award winner for its durable design and seemingly well-designed look.
Why You Should Trust Us
This review is brought to you by experienced gear tester Amber King and software engineer Edward Kemper. Amber has been testing gear for TechGearLab's sister site, OutdoorGearLab, for over six years, writing over 20 different categories. She has a history of writing in-depth testing plans to truly understand the limits of all products. This review is no exception. Eddie is a software engineer that's been at it for over six years. He currently works for Story Blocks and provided consultation for testing procedures on this review.
To start our testing process, we researched over 20+ different drives for over three hours. We chose nine top highly rated hard disk drives (HDD) and solid-state drives (SDD) that offer the best performance with the highest popularity ranking. We then purchased each one, unpackaged them, and tested for over two weeks. We look at read and write speeds for both sequential and random tests. We did this using both a PC and Mac computer, with all USB ports on each. Speeds are averaged using three different GB loads. We also perform "actual" speed tests where we dropped files of four different sizes, 2 GB, 6GB, 10GB, and 100GB. Averaging these results, we learned how different "optimal" speeds are from "actual" speeds. This really defined performance differences. For any 'rugged' drive that claimed water, dust, pressure, or drop ratings, we actually tested it put to see if they'd hold up. Yes, we even drove over two of them! Finally, we weighed and measured each so you can see a comparison of weight and size for your travel needs.
Analysis and Test Results
Our external hard drive review is extensive and in-depth. Our selection is a combination of solid-state drives (SSD) and hard disk drives (HDD). This article outlines the pros and cons of each external hard drive, highlighting the top performers. We score each based on how it does in five different categories. This unbiased and in-depth article is designed to offer suggestions and recommendations to help you find the best option for your needs. We also do our best to debunk company claims by reporting our results below.
Backing up data and/or playing files right from your external drive should be fast and efficient. To test this, we look at two different metrics; Optimal Speed and Actual Speed. Based on all the tests we perform, we learn that all manufacturers overexaggerate read and write speeds. No product tested actually showed a speed that was as high as the manufacturer claimed. The fastest SSD is Samsung SSD T5 500GB (our Editor's Choice award winner), while the WB My Book Desktop 3.0 3TB is the fastest and most consistent HDD.
This test shows us how fast a drive can perform when only drive performance is isolated, and system functionality is limited. To test Mac systems, we used the BlackMagic Speed Test. To test the Windows platform, we used the CrystalMark Test. For the Windows test, we gathered data on both sequential and random tests, as well as speed information on USB-C and USB-A ports. Sequential tests show how well a drive reads a file from point A to point B. While random tests show how well it can access random data points in a large database.
The sequential test data is more important than the random test data unless you are going to be working off your hard drive directly. This tells us how fast the drive can read and write a large chunk of data or how fast it might transfer from one place to another. These times are much faster than random tests. The Samsung Portable proves to crush the competition in all tests, showing a high read speed of 462 MB/S with variation in the write speeds based on the USB port used. The LaCie Rugged Raid proves to have a very fast optimal speed as well.
The random tests tell us how fast it can access random data without a sequential pattern already recognized. Basically, it dives into the database of information to find a file, read, and write it. Once again, the Samsung Portable drive offers the best random speed results, making it a great external drive to work from directly.
Actual Speed Tests
While the BlackMagic and CrystalMark tests gave us great data to see how these drives would perform in optimal conditions, perhaps the more important test is the 'actual speed test'. For this test, we built four different file sizes of 2GB, 5GB, 10GB, and 100GB. We then manually timed each drive to see how long it took to drag and transfer the file from our Mac desktop to the external hard drive. We then calculated the MB/s and averaged all the different file sizes. Most external drives have a significant decrease in speed as file size increases. The only drives that stayed relatively consistent across files sizes are the WD Easy Store and LaCie Rugged Disk.
Of all the drives, the Samsung Portable T5 offers the fastest actual speed (237MB/s), followed by the WD Easy Store Desktop (148 MB/s). Of the rugged drives, the LaCie Rugged Drive provides the fastest actual speeds at 81 MB/s. The average speed amongst all competitors sits around 96 MB/s. Know that when you buy a drive, you can expect the actual speed to be almost half the claimed speeds.
Weight and Profile
Weight and portability have grown in importance as jobs become remote, and workers are constantly in travel. Some heavier drives are designed to simply sit at your desk while others, like the Samsung Portable T5, fit in the palm of your hand. Solid State Drives have made optimal portability with lighter constructs. Hard Disk Drives are typically bulkier and heavy, but some companies are crossing barriers, making HDDs more portable for travel. We weighed and measured each drive to get a clear comparison of transport performance.
It's not surprising that the Samsung Portable T5 (1.75oz) crushes in this category. Its dimensions (3X2.25X1/8 inches) fit easily into your pant pocket, a purse, or the smallest pockets of your backpack. It's by far the smallest drive with the largest capacity that we've tested. The Seagate Portable 2TB (5.4oz) and the Toshiba Canvio Basics TB (5.9oz) are two other lightweight drives. The Toshiba Canvio is a little smaller in size (3X4.25X0.5 inches) in comparison to the Seagate Portable (4.5X3X0.5 inches). Of the durable HDD drives, the Silicon Power 2TB is the most lightweight (8.70oz) and rugged drive we've tested. This HDD features a slim profile (5.5X3.25X0.25 inches), similar to the Seagate Portable and Toshiba Canvio Basics.
Ease of Use
Drives that have easy plug n' play capabilities that don't need reformatting when changing systems do best in this metric. Navigating a complex software system is a royal pain in the butt. To test this, we note which drives are the easiest to set-up and which took extra research to start using. We also look at the hardware to see which only requires power from the cord, versus an additional power source.
The drives that perform the best in this metric are the simplest to use. The ADATA Rugged Drive, our Editors' Choice, doesn't need to be reformatted for Mac computer. It plugs into any system and starts working. There's no need to install software like the WD My Book Desktop Drive or even punch in a password like the Samsung Portable SSD. Most external hard drives prove to be relatively easy to use. The hard disks that were formatted for both Mac and Windows include the LaCie Portable storage, Buffalo Mini Station Extreme, and the Samsung Portable T5. All others come formatted for Windows, and macOS needs to be reformatted (which is pretty easy).
We also appreciate that the ADATA Rugged Drive doesn't need an additional power source like other HDD's like the LaCie Rugged Raid and WD My Book Desktop Drive. All smaller drives were powered right from their USB cords.
This metric brought us great joy to test. For this category, we noted the claims made by companies when it comes to durability and ruggedness, and put them to the test. Several of the drives in this selection claim to have a rating against water, dirt, and pressure; one durability test we subjected all hard drives to is the drop test. We start with a hip-high drop, then a shoulder-high drop. We perform both on the carpet, then on concrete. Between each test, we check to see if the drive is still working. Luckily, most drives survived, keeping your data safe if you accidentally drop it off the table.
The Adata HD830 2 TB is the most rugged drive and completely wowed us. We immersed it in water for two hours, drove over it with our Toyota Tacoma pick-up, mashed it in the dirt, and even dropped it from six feet overhead. In all tests, it immediately kept working, with all of our files intact. The LaCie Rugged Raid is another heavy-duty drive that doesn't do as well in our tests. While it did survive our drop tests and being driven over by a Subaru, its life was ended when we soaked it with water. The fatal flaw, we suspect, is the exposed USB-C port that definitely couldn't take the continuous spray of water (from any direction) that LaCie claimed it to be rated for.
The Silicon Power Rugged Portable Drive is another we are impressed with. While it's advertised to be super durable, it's only rated to withstand a small spray of water (not continuous), which is akin to accidentally spilling a glass of water over the top of it. It's not pressure rated like the Adata or LaCie storage. It can, however, take on dusty conditions.
All the drives we tested were able to withstand our standing drop tests, except for the Buffalo MiniStaation Extreme despite its tough-looking exterior. Of the drives that aren't advertised as "super-durable", the WD Black seems to be the toughest. The case is shock resistant, and we suspect it'd hold up to a few drops of water on its surface.
We love features! Software that provides excellent security and data recovery equates to better reliability. Drives that come with several cords or adaptors earn higher points in this category. Of the competition, we are most impressed by the LaCie Rugged Raid shuttle because it features several encryption and storage options. It includes specific software and even comes with a one month free trial for Adobe products.
We also love the Buffalo Miniworks that comes with two different adaptor cords, one of which is actually attached to one of the drives. It features AES 265 automatic data encryption and a great security system that uses a card or password for harddisk entry. It stands out as one of the most secure hard drives we tested. Plus, despite our results for the drop tests, it does have a fairly rugged exterior that seems to be water and dust resistant. Both the LaCie Rugged Raid and Buffalo Miniworks drives come with data recovery services.
With such a vast selection of external hard drives on the market, it might be challenging to choose one best for your needs. We hope our extensive and unbiased research aids you in your search. Our award winners are chosen based on hands-on experience, with the intention to help you find the best external hard drive options on the market.
