FAQs
Why would I need an external hard drive?
External hard drives provide portable storage space for files, allowing you to increase the total storage of your computer, share files between computers, or simply keep backed-up files secure in case something happens to the originals. If your computer is slowing down or you’re getting warnings about low storage space, it might be time to invest in an external hard drive to free up some space on your computer’s internal hard drive.
What’s the difference between a hard disk drive (HDD) and a solid-state drive (SSD)?
You’ll find external hard drives in HDD and SSD versions, and they both perform the same function—with a few distinct advantages. HDDs have been around much longer and stores files by way of a spinning electromagnetic disk, whereas SSDs rely on flash memory chips for storage and therefore have no moving parts. This means SSDs are usually faster, more dependable, and more expensive. You can get much more storage for a fairly cheap price with an HDD.
How are external hard drives powered?
Some external hard drives get their power from the computer itself transmitted over the data cable, and others require the additional power from an AC outlet. All external hard drives connect to the computer either by USB, FireWire, eSATA, or wirelessly, and this connection type is directly linked to transfer speed.
Digital storage is changing. Internal storage drives are getting bigger, cloud storage is getting cheaper, and USB drives are getting less common. But that doesn’t necessarily negate the need for a good external hard drive — in fact, sometimes they’re the best way to go.
Buying a hard drive isn’t as simple as purchasing the first (or cheapest) one you see. There are a number of factors to consider when buying an external storage drive, and the kind of drive you ultimately end up buying could dictate what you’re able to do with it.
So what should you keep in mind? For starters, you’ll want to decide between a hard drive and a solid-state drive, both of which offer some major advantages and disadvantages. You’ll also want to think about drive speed, hard drive format, connectivity, and special protection features.
Before diving into our guide, there are a few terms you should know. You'll most likely be deciding between a drive of multiple gigabytes (GB), or multiple terabytes (TB). One terabyte is 1,000 gigabytes, and one gigabyte is 1,000 megabytes (MB). An MP3 file takes around 3.5MB, meaning that one gigabyte can store around 285 songs. One HD movie takes up around 3.5GB — so one terabyte can store 285 HD movies.
Here’s everything to consider when buying an external drive.
Storage Size
The most important thing to consider is the size of your drive. We’re not talking how physically big, but rather, how much storage you want. It’s hard to recommend a storage size because it varies from person to person and largely depends on what you plan on storing. A good rule of thumb, however, is to determine how much storage you think you’ll need and then buy a drive that’s double.
If you plan on storing documents only, you probably don’t need much more than 80GB. If you’re storing a small to medium music collection and photos, then up to 256GB should be fine. For storing movies and other video content, the amount you need could range into the multiple terabytes, especially if the movies are in 4K. Ultimately, it’s always good to get more storage than you think you’ll need — even if it means shelling out more money.
Types of External Drives
Next, it’s time to decide on the kind of storage drive you want. There are two main types of external storage drives, and while they ultimately serve the same purpose, the way they store files is markedly different.
Traditionally, if you wanted a storage drive it meant buying a hard disk drive. There are some advantages and some disadvantages to this. For starters, hard disk drives have been around for quite some time, so they’ve become relatively cheap. They function by storing files on an electromagnetic disk that spins around and is read by a moving arm.
Because of those moving parts, they’re much more likely to break with a lot of movement. The speed of a hard disk drive is essentially dictated by how fast the electromagnetic disk spins, and they're generally slower than solid-state drives. (We’ll get more into the different speeds later.) Hard disk drives are the way to go, however, if you want a lot of storage at a cheap price and don’t plan on moving them a lot.
Solid state drives do away with the moving electromagnetic disk, and replace it with what’s called “flash storage.” That’s the same kind of storage that’s used in smartphones, RAM in computers, and, these days, many of the internal storage drives in computers. Solid-state storage essentially uses microchips to store information, and as a result, there are no moving parts. That means there’s a lower failure rate, higher speed, and simply better overall performance. In particular, that means they’re great for running software or an operating system off of.
Of course, there is a downside to all of those advantages — and that’s price. Solid-state drives are much more expensive than hard disk drives, and while they are going down in price, you simply can’t get multi-terabyte solid-state drives without spending at least a few hundred dollars.
Performance
There are a few things that can affect the performance of a hard drive beyond simply what type of hard drive it is. That’s truer of a hard disk drive than a solid-state drive, but solid-state drives still have performance-related metrics that you should pay attention to.
The transfer speed of a hard drive largely has to do with the type of connector that the hard drive comes with. Newer connection standards have higher transfer speeds. The term “transfer speed” is technically a little misleading, as it doesn’t really dictate exactly how fast a hard drive can transfer files to and from your computer. Instead, it tells you how fast a hard drive can theoretically transfer files, based on the connection protocol the hard drive uses.
In the past, the connector was the main limiting factor in how fast a drive could transfer files: USB 2.0 hard drives, in the real world, could transfer data at up to 20 MB/second, while FireWire 800 drives limited things to 85 MB/second. These days, the newer USB 3.0 standard allows for data transfer at up to 460 MB/second, while Thunderbolt allows for speeds of over 1GB/second. Because of that, the connection type isn’t the bottleneck. Instead, the speed is dictated by how fast the hard drive can read and write data, which is referred to as the read/write speed.
Read/write speeds refer to how quickly a hard drive can access the files stored within it — not how quickly those files are transferred to or from a computer. The “read” speed refers to how quickly a hard drive can access a stored file, while the “write” speed refers to how quickly a drive can save a new file. Given the development in transfer protocols, read/write speeds are a much better indicator of how fast your hard drive will be able to actually transfer files than “transfer speed,” especially when it comes to hard disk drives.
Read/write speeds change a lot depending on whether it’s an HDD or SDD, and even within those categories there can be some variation. As mentioned, HDDs have a spinning disk inside of them, and the rate at which drives can access data depends on how quickly that disk spins. Commonly, drives spin at 5,400RPM, or rotations per minute, and drives at that speed generally have a read/write speed of around 100MB/s. Some HDDs have a physical speed of 7,200RPM, which allows for a slightly faster read/write speed of 120MB/s.
Read/write speeds can vary a lot with SSDs, but typically they range from 200MB/s at the slowest to multiple GB per second at the fastest. If all you’re doing is transferring files, then any of those speeds should be more than enough, but if you’re using your drive to store software or your operating system, then something on the fast end might help. In that case, look for speeds of 500MB/s or more.
Other Features and Considerations
While the type of hard drive and performance of the hard drive are perhaps the most important factors to consider, there are a few other features to keep in mind.
While most consumer-level hard drives connect to your computer through a USB cable, some offer network connectivity instead, meaning you can access your hard drive from any computer or phone that’s on the same network. That can be pretty helpful for those who have multiple computers set up and simply want to use an external hard drive to back up files and transfer files between computers.
You can actually give any external hard drive network features by simply plugging it into your router — providing your router has a compatible port on it — but it will require a little more tweaking to get set up properly. Still, special network-connected drives have some advantages. For example, so-called “Network Attached Storage” or NAS, can be used as a media server by apps like Plex, while standard router-connected drives aren’t necessarily able to do so. NAS is a little more expensive, but it’s also often expandable thanks to extra slots in the enclosure, which can accept more actual hard drives.
Check out our guide to the best NAS (Network Attached Storage).
The kind of port or ports that your hard drive uses to connect to a computer is very much linked to transfer speed. Most hard drives connect to a computer through a form of USB. That could mean the now-outdated USB 2.0 or the newer USB 3.0 or USB 3.1, and if it is USB 3.1, it could also connect through the newer USB-C connector, while still using the USB 3.1 standard.
Other ports, which are increasingly less common, include FireWire 400 and FireWire 800, though fewer and fewer computers support those ports, so you should be wary of that when purchasing.
We recommend looking for a hard drive with USB 3.1 support and a USB-C connector, especially if your computer is relatively new. It might mean having to buy an adapter to use with your current computer that may not have USB-C, but it means that when you upgrade to a new computer, your external hard drive will stay usable.
Check out our guide to the best USB-C adapters available.
External hard drives come in a few different formats, though it’s very easy to reformat a hard drive if you happen to buy the wrong kind. Hard drive formats are largely linked to the operating system that you’re going to be using the hard drive with. Here’s a quick rundown.
NTFS is the most common format for new external hard drives and can be used with Windows computers. Unfortunately, it doesn’t work as well with any other operating systems. Macs can read NTFS-formatted hard drives, but can’t write to them.
HFS+, which stands for “Hierarchical File System,” is a hard drive format that works much better with Macs, and it’s an improvement on the older HFS format in that it can support larger file types. Unfortunately, HFS+ drives don’t really work with Windows computers. HFS+ drives are the way to go for those who plan on using them with Macs that are running slightly older versions of macOS.
APFS is a newer hard drive format that works with Mac computers, but it only works with Mac running macOS High Sierra or newer. Like HFS+ drives, APFS drives can’t be read by Windows computers.
exFAT is essentially a mix of NTFS and FAT32, an older drive format that’s not used much anymore. There are a number of advantages to exFAT drives — namely that they can be recognized by both Windows and Mac computers, so if you need support for both, it’s worth formatting your drive to exFAT.
If you’re not sure what hard drive format to go for, then go for exFAT, since it works with most operating systems. Most hard drives come in NTFS, though, so you may need to buy one and then reformat it. Keep in mind it's not as easy to reformat a HFS+ or APFS drive if you need to use it on Windows.
The physical size of an external hard drive doesn't necessarily translate to the amount of storage space, particularly with the advent of flash storage. You really only have a say in the physical size of a hard drive when it comes to solid-state drives, as there are standard sizes for hard disk drives. Hard disk drives’ spinning disks can come in either 2.5-inch or 3.5-inch sizes. A standard size for a portable hard disk drive, for example, is the Western Digital Elements 2TB hard drive, which comes in at 4.35 x 3.23 x 0.59 inches. Smaller desktop hard drives come in at around 7 x 5 inches and range up from there.
Solid-state hard drives can be much smaller, making them much more portable. The SanDisk Extreme Portable SSD, for example, comes in a size of 3.79 x 1.95 x 0.35 inches — a fairly average size for solid-state drives.
External hard drives can come with features designed to keep files more secure, which might be important if you plan on using yours to store sensitive information. For example, some hard drives offer password-protection by default, meaning you can easily set a password to keep all your files safe. Some also offer high-level encryption, rendering your files useless to those who don’t have your password, even if they manage to somehow hack into the drive.
A hard drive buffer is essentially storage that exists between the computer and the actual storage in a hard drive. Files stored by the hard drive in the buffer can be accessed far quicker than those stored in the main storage of a hard drive, and the bigger the hard drive buffer — sometimes called the cache — the better the overall performance the drive is likely to have.
Generally speaking, you really only need to care about the size of the buffer if you plan on running software from your hard drive. If all you’re doing is storing files, the type of drive and the speed of the disk will be much more important.
If you do feel as though you need a hard drive with a larger buffer, then we recommend getting one with at least a 64MB cache, though those with 128MB and even 256MB are pretty common, too.
Price
Depending on the type of hard drive and the amount of storage you opt for, the price can vary drastically.
Hard disk drives, as mentioned, are much cheaper than solid-state drives, so if you need a lot of storage at a reasonable price, a HDD might be the way to go. You can expect to pay around as little as 3 cents per GB for a HDD.
On the other hand, it's not uncommon to see a solid-state drive that runs into 25 cents per GB. Lower-capacity SSDs might range up to 40 cents per GB, while 2TB SSDs might come at 20 cents. Of course, that still makes for a drive that costs hundreds of dollars.
Conclusion
While there's a lot to keep in mind when buying an external hard drive, hopefully, this will help you narrow down your selection. Our overall recommendations? If you want lots of storage at a reasonable price, and don’t plan on moving your hard drive around a lot, go for an HDD. If you want fast performance and either don’t need a lot of storage or are willing to spend more, then an SSD is your best best. In both cases, it’s a good idea to find a drive that supports USB 3.0 or later, and a USB-C port might be helpful depending on whether your computer has a USB-C port.
There are a few brands that have built a reputation for quality external hard drives, including Western Digital, SanDisk, and Seagate. It’s often worth buying a hard drive from a reputable brand, as smaller companies may not offer much in the way of support for faulty drives.
Rest assured, no matter what your needs are there’s likely a hard drive out there for you, and hopefully purchasing is a little easier with your new-found knowledge of their key features.
It's a Great Time to Go for a Drive
In an era when Apple charges 99 cents per month for 50GB of iCloud storage and Google offers 100GB of free storage for two years with the purchase of a new Chromebook, mainstream external hard drives might appear less essential than they once were.
But modern external drives are faster, more stylish, and often more durable than their counterparts from a few years ago. They're ever cheaper and more capacious, too. For about $50, you can add a terabyte of extra storage to your laptop or desktop by just plugging in a USB cable.
Choosing an external drive isn't as simple as buying the most expensive one you can afford, however. The capacity and type of storage mechanism are the two most important factors to consider, and each one will increase or decrease the cost dramatically depending on your needs. Other factors include the physical size of the drive (is it designed to be carted around or to sit on your desk?), how rugged it is, the interface it uses to connect to your PC, and even what colors it comes in. This guide will help you make sense of all the options. Here are the key questions to ask as you shop.
The Need for Speed: Hard Drive or SSD?
Solid-state drives (SSDs) have fewer moving parts than traditional hard drives, and they offer the speediest access to your data. Unlike a conventional disk-based hard drive, which stores data on a spinning platter or platters accessed by a moving magnetic head, an SSD uses a collection of flash cells—similar to the ones that make up a computer's RAM—to save data.
Just how much faster is it to access data stored in flash cells than those stored on a spinning platter? Typical read and write speeds for consumer drives with a single spinning platter are in the 100MBps to 200MBps range, depending on their USB interface and whether they spin at 5,400rpm (more common) or 7,200rpm (more expensive and less common). External SSDs offer twice that speed and sometimes much more, with typical results on our benchmark tests in excess of 400MBps. Practically speaking, this means you can move gigabytes of data (say, a 4GB feature-length film, or a year's worth of family photos) to your external SSD in seconds rather than the minutes it would take with an external spinning drive.
Not only is it faster to read and write data stored in flash cells than those stored on a spinning platter, but it's also safer. Because there is no spinning platter or moving magnetic head, if you bump the SSD while you're accessing its data, there is no risk that your files will become corrupted and unreadable.
While external SSDs are now readily available and cheaper than they were a few years ago, they're not a complete replacement for spinning drives. Larger external drives designed to stay on your desk or in a server closet still mostly use spinning drives, taking advantage of their higher capacities and lower prices compared with SSDs.
Physical Size Matters: Desktop or Portable Drive?
If you have a large photo or video collection—perhaps you are a photo or video editor, or maybe a movie buff—you'll likely need several terabytes of space in which to store it. So your best option is a desktop-class drive. We define these as having one or more spinning-platter drives inside and requiring its own dedicated power cable. Of course, in this scenario, your files are going to have to stay at your desk.
A desktop drive with a single platter mechanism inside will typically use a 3.5-inch drive inside and will be found in capacities up to 12TB, and most are roughly 5 inches tall and 2 inches wide. In addition to storing large media collections, these drives can also serve as inexpensive repositories for backups of your computer's hard drive that you schedule using either the software that came with the drive or a third-party backup utility.
The next size up for consumer desktop drives is about the same height but twice as wide to accommodate additional drive mechanisms in the chassis, such as with the Western Digital My Book Duo. These larger drives are more expensive but also much more capacious; the highest-capacity current models employ two drives for up to 20TB of storage. Note: In the case of these and single-platter-drive products, you're not meant to swap out the drive or drives inside.
The largest desktop drives are often much, much larger than the first two categories, so large that you'll want to stick them under your desk or in a dedicated server closet. They're mostly intended for professional use in editing studios, surveillance control rooms, and the like. Their defining characteristic is the ability to swap drives in and out easily, so they provide quick access to the drive bays at the front of the device. Most are sold without drives included, so you can install any drive you want (usually, 3.5-inch drives, but some support 2.5-inchers). Their total storage capacities are usually limited only by their number of available bays and the capacities of the drives you put in them.
At the other end of the physical-size spectrum are portable drives, some of which now use an SSD inside instead of a spinning platter to save space, as well as to increase throughput and durability. These drives can be truly tiny, weighing just a few ounces and with their largest sides measuring less than 3 inches long, like with the Samsung Portable SSD T5. Others use spinning platters and are a bit larger, like the LaCie Porsche Design Mobile Drive, but they still fit easily in a purse or even a coat pocket. Portable drives get their power from the computer to which you connect them, through the interface cable, so there's no need for a spare wall outlet.
Need Redundancy or Extreme Speed? Consider a RAID
If you buy a larger desktop drive with two or more spinning platters, you'll almost certainly have the ability to configure the drive as a RAID array using included software. Depending on which RAID level you choose, you can prioritize capacity, speed, or data redundancy, or some combination thereof.
A collection of spinning drives configured with a RAID level designed for faster access can approximate the speeds of an SSD, while you should consider a drive with support for RAID levels 1, 5, or 10 if you're storing really important data that you can't afford to lose. Hit the link above for explanation of the strengths of each RAID level.
What Interface Should You Look For?
How an external drive connects to your PC or Mac is second only to the type of storage mechanism it uses in determining how fast you'll be able to access data. Unfortunately, these connection types are constantly changing, and the internet is littered with outdated references to legacy interface types such as eSATA and FireWire.
Right now, the fastest mainstream connection type is Thunderbolt 3, which is handy assuming you have a newer laptop or desktop with a Thunderbolt 3 port. All late-model Apple laptops have them, but they're much scarcer on Windows machines. This interface uses a USB Type-C connector and offers blazing throughput of 40GBps. As an added bonus, a desktop drive that supports Thunderbolt 3 might also come with additional DisplayPort and USB connections that allow you to use the drive box as a hub for your keyboard, mouse, monitor, and other peripherals.
You'll really only see the speed benefits of Thunderbolt 3, however, if you have a drive that's SSD-based, or a RAID array. If you'd rather save money than time transferring your data, if you're buying a desktop drive with a single platter-based mechanism inside, or if you have a PC that lacks Thunderbolt 3, you'll want to make sure your drive has a USB connection. Nearly every recent drive we reviewed supports USB, and the same goes for laptops and desktops.
Not all USB ports are created equal, though. The most prevalent is the standard rectangle shape (called Type-A) that's been present on devices for decades. The oval-shaped Type-C connector is quickly gaining traction, though. It's capable of supporting the USB 3.1 standard in addition to Thunderbolt 3, though most Type-C ports include only the former. If you buy a drive with a Type-C cable, make sure it also includes a cable with a rectangular Type-A plug if your PC lacks a Type-C port. Otherwise, you'll need to buy a separate cable or adapter.
Do You Need to Go Rugged?
If you carry your drive around frequently, you'll want to pay attention to how rugged the drive is. Some models include plastic bumpers, and some even meet military standards for shock and dust protection. (Look for support for specifications such as IP67 or IP68.)
And of course, if you're carrying your drive around with you, you want it to look nice. Some, like the Samsung T5, come in multiple colors, while others, like the ADATA SD700, are super-slim and ready to be tossed in a pocket.
Perhaps the only thing you don't need to pay much attention to is the warranty. If your drive breaks because you damaged it, the warranty likely won't cover it. Even if the drive fails because of a manufacturing defect, most warranties simply replace the drive and don't cover the cost of recovery services that attempt to rescue your data from the broken drive.
Let's Look at the Top Models We've Tested...
Also know that you can find external drives that do way more than just store your data. Some include SD card readers to offload footage from a camera or drone in the field, while others have built-in Wi-Fi and can double as an all-in-one home media server. Some of that kind even come with extra-large batteries that can charge your smartphone while you're on the go.
To get you started in the right direction toward the right add-on backup/storage solution, below are 10 of the best drives we've tested of late, at a variety of prices and capacities. Some are SSD-based, while others are platter.
