External hard drives are one of the single most useful accessories you can buy for your computer.

They allow you to instantly increase the amount of permanent storage you have.

And that’s just one of the many benefits of owning an external hard drive.

But they were also ridiculously expensive.

The good news though is that hard drive storage space is cheaper than it ever has been.

And that includes external hard drives.

Right now, you can get 1TB of external hard drive storage for as little as $50.

The question now though is – which is the best external hard drive for your needs?


There are two basic types of hard drive – solid state and mechanical.

A mechanical hard drive has moving parts like the platters (disc), spindle motor, actuating arm, etc.

These are the most common type of hard drive, but are obviously prone to wear and tear.

But they’re also pretty cheap to buy, even when buying drives with multiple terabyte (TB) capacity.

A Solid State Drive (SSD) has no moving parts – they use the same type of memory you find in USB flash drives.

Fewer moving parts means these drives are technically less prone to wear and tear.

But they’re also much, much faster than a typical mechanical drive.

They’re also more rugged than a mechanical drive – they’re very difficult to damage like a USB flash drive is difficult to damage.

But if you drop an external mechanical drive onto a hard surface you can kiss your data goodbye.

Are there downsides?

Sure, and the first is that SSDs are typically far more expensive than a mechanical drive, especially if you want a 1TB+ drive.

Another is that SSD drives start “failing” from the first time you write data to them – it’s not unusual for an overused SSD to simply die after 2 – 3 years of use

Now that we have the terminology out of the way, let’s take a look at some of the better external hard drives on the market.

Samsung T5 1TB SSD external hard drive

Samsung is a brand name most often associated with smartphones and tablets.

But they also manufacture some of the best external hard drives on the market – the T5 SSD is just the most recent example of that.

The most important feature of this external hard drive is the fact that it uses SSD technology.

This means it’s up to 5x faster than a standard external hard drive.

But it also comes in a metal case, which means it’s designed to take at least some punishment.

So you get a killer combination of speed, looks and reliability.

Western Digital Elements 10TB desktop drive

And now we swing from away from highly portable external hard drives to one that’s designed to stay in one place.

A WD Elements was my first proper external hard drive.

But that was back when 300GB was considered a lot of storage space.

What you get for your money with the WD10TB is 10 Terabytes of storage space in an externally powered hard drive that’s designed to sit on your desktop.

You can unplug it and take it around with you, but these drives aren’t really designed for that.

In terms of data transfer rate you’ll only get the very best from this drive when it’s connected to a USB 3.0 port.

But it’s also happy to connect to a USB 2.0 port, just with a much lower data transfer rate.
  • Storage capacity: 10TB (10,000 Gigabytes)
  • Interface: USB 3.0
  • Data transfer rate: Up to 180MB/s
  • Compatible with: Windows 7, 8.1 and Windows 10

Aegis Apricorn Padlock Fortress

If somebody steals your hard drive they’ll have access to every single file on it – including anything sensitive or personal.

Unless you invest in something like the Apricorn Aegis Padplock Fortress.

While this might look like a regular external drive, it’s actually got some really cool stuff going on inside and outside.

You’ll notice that the exterior of the case has a built-in keypad – this is for your user access PIN to unlock the drive.

But this isn’t the only security feature because this device also features real-time 256-Bit AES XTS data encryption.

The interior electronics (and the drive itself) are secured with a layer of epoxy resin, so your data remains completely safe even if somebody breaks the case apart.

This drive also isn’t a slouch when it comes to performance thanks to the USB 3.0 interface.

Yes, the real-time encryption will cause a slightly slower data transfer rate, but the difference is marginal.

It even comes with an integrated USB cable and is also dust and water resistant to IP66 standards.

Transcend 1TB 25M3 StoreJet

The majority of external hard drives have one fault in common – it doesn’t take much to break one.

Just dropping it a few feet onto the ground is enough to kill most drives stone dead.

That’s where the Transcend 25M3 StoreJet hard drive comes in handy – it’s designed to taken punishment.

So instead of just a basic plastic case, the drive in your Transcend StoreJet is protected by a 3-stage anti-shock system.

The internal shock dampener keeps your drive safe from impact energy, then the secondary metal case keeps everything in one place while adding even more protection.

And then finally the outer silicone layer provides another layer of protection.

Western Digital My Passport 2TB

What if you just need a drive that offers plenty of storage, is decently fast and doesn’t cost 5x as much as everything else?

In that situation you could invest your cash in a Western Digital My Passport drive.

These are standard mechanical/SATA external hard drives in a sleek case.

It’s not just about looks though – these drives also offer very high file transfer rates thanks to their USB 3.0 interface.

Although they are obviously backwards compatible with USB 2.0

But they’re also not going to be speedy as an external SSD drive, for example.
The 2TB of storage space kinda makes up for that though.

The ‘My Passport’ models also come with built-in 256-Bit AES encryption as part of the drive management software suite.

In the interest of full transparency here – I own several of these drives and I love them.

Basically, because they last well beyond their warranty, in my experience.
  • Storage capacity: 2TB
  • Interface: USB 3.1
  • Data transfer rate: 120Mbps in real life
  • Compatible with: Windows 7 or later, MacOS
  • Data encryption: Yes

  • Power adapter required: No


  • A highly portable external hard drive – if would fit in a shirt pocket
  • USB 3.1 interface offers file transfer speeds at least 5x fast than standard USB 2.0
  • Western Digital is one of the oldest hard drive manufacturers in the world i.e. quality products
  • Extremely affordable when compared to SSD or even other mechanical drives
  • Easy to set up even for complete newbies
  • Available in a variety of colors
  • Western Digital drives tend to last and last and last


  • The drive management software is annoying at times

External hard drive buyers guide

Okay, so you’ve had a look at the reviews above and you’re still not sure what drive would best suit you?

No problem.

There’s a lot of information to absorb.

So, let’s take a look at the types of questions you need to ask yourself in relation to the type of external hard drive you need.

Not want – need.


Do you need your new drive to move or copy files so quickly that it almost seems miraculous?

If so, then invest in an SSD external hard drive – their data transfer rates make other drives look like they’re standing still.

But if you can afford to wait a few moments for all those files to get where they’re going, then a standard mechanical external drive will fulfill that need.

The majority of portable hard drives sold right now are mechanical drives.

And what about USB 3.0 vs. 2.0?

Always choose a USB 3.0 hard drive because:

  1. It’s backwards compatible with a USB 2.0 connection
  2. You can always get a USB 3.0 adapter card for your PC

Storage space

I know that it can be tough to decide on exactly how big your hard drive needs to be.

Bu the thing is that hard drive storage has never been cheaper than it is right now.

So aim for at least 1TB of storage space, regardless of whether you’re getting a standard mechanical drive or an SSD.

More storage space is always better.

Plus, it’s much easier to manage 1 large drive than several small ones e.g. 2TB = 1 x 2TB, 2 x 1TB or 4 x 500GB.

The biggest external hard drives available right now come with around 18TB of storage.

But they’re almost always desktop models and not designed to be carried around with you.


This is a big one for me simply because I’ve had to endure several hard drive failures in the past.

Some of those were my own fault, but some of it had to do with “taking a chance” on drives that seemed like a good deal.

What’s important or remember here is that if your drive fails then it takes all your files with it.

Yes, you might be able to pay a data recovery company to restore most of your files, but they tend to have a 75% – 90% success rate at best.

So that still means you’ll lose anywhere up to 25% of your data.

You can get around this potential problem by only buying drives from brand names that you recognize.

Or simply paying attention to user reviews and seeing how often a given model fails over its first year or two of ownership.


My first external hard drive was as big as a single volume of a printer encyclopedia – it was huge!

But that was still far more portable than carrying my desktop computer around with me.

Or my equally huge laptop.

External drives now all tend to be highly portable, with the exception of dedicated “desktop” models that need an external power supply.

So all you basically need to decide is how often you’ll need to transport files with you.

If that’s quite often then get an external drive that does not require a separate power supply.


Do you need a hard drive that encrypts your data?

Generally speaking, the answer is “It depends”.

If you plan on storing lots of sensitive personal information on your portable drive, then yes, you absolutely should encrypt it.

The problem with encryption (for novice users) is that if you lose you decryption key/your PIN, then the drive will auto-erase itself.

So you lose your data either way.

Data encryption is a nice feature but it’s not really a “must have”, again unless you’re storing extremely sensitive data on your drive.

Built-in Wi-Fi

Being able to transfer your files wirelessly over your home network is a nice feature.

But do you really need it?

If your external drive is part of a NAS (Network Attached Storage) setup for your home network, then Wi-Fi access can be useful.

Especially for some kind of “offsite” backup system i.e. you have an archive drive set up in another room.

Apart from that, you’re probably paying for features you don’t need.

Also, Wi-Fi is going to be much slower than a physical connection when transferring files.

And transferring big files over a Wi-Fi network could kill connection speeds for everyone else attached to that network.


Please, please avoid those budget external hard drives.

They tend to come from “no name” brands and are mass produced in drive facilities where quality assurance isn’t an issue.

What this means is that, yes, you’ll save maybe $30 when buying the drive.

But it will most likely fail within a few months, at best.

There’s also the issue that some of these super-cheap drives “spoof” the amount of available storage space.

It might say “2TB for $20” on the box, but what you’re really getting is a 50GB drive that used trickery to convince your operating system that it’s actually a 2TB drive.

You’ll only find out you were conned when you reformat the drive out of frustration.


The “best external hard drive” is a question with a lot of nuance.

Basically, it’s down to what you need the drive to do.

In most cases that’s simply to provide a place for you to backup your files, photos, etc.

The vast majority of name brand external hard drives will fulfill that requirement.

But it is worth keeping an eye on SSD external hard drives – they’re becoming very affordable so expect them to dominate the portable drive market over the next few years.
