Thinking of buying a new external hard drive for backup, upgrade, or maybe replace a damaged one? Here we have put together some insights and tips on how to choose an external hard drive. Keep reading for the details….
Why do you need to buy a external hard drive?
There are several reasons why you may want to buy a new hard drive. It might be an upgrade, a replacement, backup storage, or maybe you need extra storage for your movies, music, and games.
With that being said, the following are some of the common situations that may require one to buy a new external hard drive:
Insufficient internal hard drive storage capacity on an office or study computer:
In such cases, installing an extra internal storage drive is simply not an option.
Practitioners in certain professions:
Practitioners in careers such as graphic design, photography, programming, etc. might need a mobile material library. Combining mobility with capacity is only possible with mobile hard drives and not U disks.
Sometimes all you need an external hard drive for is to act as backup storage for your favorite movies, photos, games, etc.
There are several factors to consider when choosing external hard drives. Below are some of the main things to check out…
1. Mechanical hard drive or solid state drive
You should be clear on whether you want a mechanical hard drive or a solid state drive. On the presumption of the same brand and capacity, here are some differences between mechanical and solid state drives:
Mechanical drives are comparatively cheaper than solid state drives. Taking 1TB as the standard, the market price range for most high-end HDDs is $50-$80. On the other hand, the price range for SSD hard drives is $100-$400.
- Data transfer speed
Most mechanical hard drives have transmission speeds averaging 150MB/S. On the other hand, the transfer speeds for solid state drives average about 500MB/S. SSDs using the PCle protocol can reach top transmission speeds of 1000 – 2000MB/S.
- Noise levels
While mechanical drives have significant levels of operational noise, solid state drives tend to operate with almost no sound.
- Portability and weight
As you might have guessed, mechanical hard drives are bulkier and heavier, hence less portable compared to sleek, compact, and more portable solid state drives.
Check out the summary table below:
|Data transfer speed
|$500 – $2000MB/S
|Less portable; bulky and heavy
|More portable; compact and lightweight.
2. What size do you need?
Something else to consider when it comes to how to choose an external hard drive is its size. This has everything to do with the compactness of the drive and nothing to do with the weight. As such, the size of your external hard drive affects its portability.
Most hard disk drives (HDD) have a thickness of 2.5 inches, 3.5 inches, or 2.0 inches. If you love your external hard disk sleek and portable, we recommend choosing the 2.5”, 2.0”, or any other smaller-sized drives.
Solid state drives come in comparatively smaller sizes. They make very portable, compact, and sleek external hard drives.
3. What capacity do you need?
Capacity is arguably the most important factor when shopping for an external hard drive. In fact, this is the one factor that many people consider when shopping for hard drives. The decision on what capacity is suitable depends on a host of factors, but most importantly, it depends on your needs.
For instance, if you just want to store or back up a few music files, videos, and games, a low-capacity external drive should suffice.
On the other hand, if you’re looking for something to store or backup large files such as games, movies, documents, etc., then you need a large capacity external hard drive.
Presently, the available capacities of SSDs are in the range of 120GB – 30.72GTB, whereas HDD capacities go anywhere between 250GB and 20TB. With the knowledge of the capacity of drive needed, you should be able to make an informed choice on the best hard drive that suits your needs.
4. What type of hard drive Interface should you choose?
How to choose an external hard drive also requires one to consider the data transfer interfaces to be used. Technically, this has everything to do with the USB ports and cables supported. There are 4 main types of hard drive interfaces, each with different transmission rates. They include:
- Micro USB
- USB Type-A
- USB Type-B
- USB Type-C
Check out the summary table below for further details on transmission rates and speeds for different types of USBs.
|Max. Transmission Speed
|USB 3.1 Gen 1
USB 3.2 Gen 1*1
|USB 3.1 Gen 2
USB 3.2 Gen 1*2
USB 3.2 Gen 2*1
|USB 3.2 Gen 2*2
You might want to note that USB 2.0 is an old interface that supports very slow data transmission speeds. Most new models of hard drives use interfaces above 3.0. For the best transmission speeds, we recommend USB 3.1 Gen 1 or USB 3.1 Gen 2. Be sure to check if the cable is compatible with your computer.
With cyber-attacks and related data breaches on the rise globally, the need for a secure hard drive cannot be over-emphasized. Most new models of hard drives come with some security features to protect your data from being compromised. Some of the most common security features in external hard drives include password protection and hardware e encryption software.
At the design level, an external hard drive might have a strong casing to protect against physical tampering or accidental drops.
6. Operating System compatibility
Did you know that out of the box external hard drives are formatted for particular operating systems? That’s correct. That also implies that a drive that’s formatted for Windows 10 won’t work on MacOS or Linux. The converse is also true.
However, the good news is that the formatting isn’t cast in stone. You can always reformat the external hard drive to match a different operating system.
7. Additional considerations
Aside from the above-mentioned factors, other secondary considerations when buying an external hard drive may include:
- Aesthetic appeal: Appearance and outlook
- Support for fingerprint lock/ unlock function
- Brand Name

1. How can I tell if the life of my mobile hard drive is about to expire?
Typical signs of a failing external hard drive include, but are not limited to, file corruption error alerts, disappearing files or folders, strange sounds, and failure to mount correctly or be recognized on PC.
2. Which lasts longer, SSD or HDD?
SSD hard drives last longer than HDD hard drives. The reason is that the latter is more mechanical hence prone to wear and tear while the former has no mechanically moving parts hence tends to be more durable.
3. How do I check the life of my external hard drive?
To check the life or health of your external hard drive, search and open the Disk Utility function on your PC. Once it opens, select First Aid and proceed and choose Verify Disk to open a window with all the health metrics for your external hard drive. Items indicated in red need immediate attention while those indicated in black are fine.
That marks the end of our detailed coverage on how to choose an external hard drive. Now you should be able to shop for a good hard drive- HDD or SSD- that suits your storage or data backup needs. We do not recommend buying second-hand external hard drives because their quality, reliability, and performance are not guaranteed.
With that said, we’d like to bring your attention to the rapidly growing cloud storage technology which is slowly replacing hard drives. This is the future of data storage and backup. However, before we all migrate our data to the clouds (it might take a while before this is realized), we’ll keep using our hard drives.
