What is an Encrypted External Hard Drive Best Used For?

Data privacy is crucial for every single person. Now that most data is stored in digital form encrypting sensitive information has become a must. Along with saving you from the hassle that comes with losing your hard drive, some other uses of an encrypted external hard drive include:

Protecting Your Data

Designed to protect every form of data from virtual intruders, these encrypted drives connect to your computer through USB ports. Using mathematical formulas, they encrypt all stored data, making it impossible for others to read without the password or encryption key. Whether you’ve stored sensitive business data or family pictures on your hard drive, it’s advisable to keep it encrypted.

Storing Your Data

Similar to other kinds of hard drives, the primary function of an external hard drive is to store data. Desktop-class drives can be used to store several terabytes of data, making them ideal for movie buffs and video or photo editors. Larger desktop drives are further designed for professional use in surveillance control rooms, editing studios, etc.

Creating an Effective Backup Strategy 

Your data is only as secure as your backup. Encrypted external hard drives can also be used as repositories for backups of a computer’s hard drive. You can create this backup by using a third-party backup utility or the drive’s software itself.

What Makes These Hard Drives Stand Out?

With such a wide range of models available today, choosing a drive that best suits your needs can be extremely challenging. To ensure you don’t end up wasting your money, here are some features you should look out for:

Operating System

Make sure that the encrypted external hard drive you choose is compatible with the operating system you’re using. Most high-quality models are compatible with both Windows and Mac. However, make sure you check the compatibility before you finalize your purchase.

Data Transfer Speed

Transfer speed can be simply defined as how fast a hard drive can transmit data and is usually measured in MBps or megabytes per second. Most quality models feature USB 3.0, which enables them to transfer data at a speed of 640MBps. Compared to USB 2.0, which transfers data at 60MBps, USB 3.0 is almost 10 times faster. Therefore, if you’re planning on transferring large files, it’s better to avoid USB 2.0.

FIPS Compliance

If you’re looking for a model with a decent protection level, then it’s better to purchase a FIPS-compliant encrypted drive. These models adhere to strict security guidelines and regulations, ensuring the best protection for all data stored on the drive.

Pros and Cons of Encrypted External Hard Drives

When it comes to storing, encrypting, and retrieving data, encrypted external hard drives have truly been revolutionary. To help you better understand their function, here are some of their pros and cons:


Along with being an effective and easy way of backing up files, some other advantages of an encrypted external hard drive include:

Portability and Compatibility 

Since external hard drives have a common USB interface, they’re extremely portable. They can be quickly connected to any laptop or desktop computer, and can even be connected to certain smartphones and mobile devices. This portability and quick connectivity ensure you always have access to your data, even if the primary host system gets lost or breaks down.

Fewer Hacking Concerns

As you have total control over who accesses your data, using an encrypted external hard drive significantly reduces hacking concerns. Disconnecting the hard drive when it’s not in use, or keeping it in a fireproof safe will further help protect it from prying eyes.

Avoid Encryption Errors

Manually encrypting drive data can lead to mistakes. Since encrypted external hard drives feature full automatic encryption, there are virtually no encryption errors.


However, no product is perfect. Some disadvantages of encrypted external hard drives include:

Fail Eventually 

At some point, all physical drives will fail and stop working. Most drives are mechanical devices designed with spinning platters, making them susceptible to heat and other natural elements, which can result in physical failure.

How to Encrypt Your Hard Drive

The best program for encrypting a hard drive depends on the operating system you’re using. Operating system vendors know how valuable your data is to you, and thus, each OS has its own utility that can be used to encrypt a hard drive during installation. If you want to encrypt your hard drive, you can follow these simple steps:

Encrypting a Hard Drive in Windows 7, 8, and 10

1. Select Start > Control Panel > System and Security > Bitlocker drive encryption

2. Select ‘Turn on Bitlocker’

3. Choose a passphrase, startup key, or a PIN to decrypt the hard drive. It’s advisable to select a pin with 8-20 characters and write it until you’ve memorized it. If you’ve chosen a startup key, you can create a backup on a flash drive. 

4. Print or save the recovery key. It’s advisable to do both, so you don’t lose your data. You can also save the recovery key to a Microsoft account. 

5. Restart the computer, and the encryption process will begin.

Encrypting a Hard Drive in MacOS

Because of its strong pro-privacy stance, Apple as enabled FileVault by default since OS X Yosemite. So, if you’re running Yosemite or later, full disk encryption might already be enabled. You can check this by selecting the Apple icon > system preferences > security & privacy. If it’s not enabled, you can follow these steps:

1. Select Turn On FileVault

2. Type in an administrator username and password. If multiple user accounts exist, select the ‘Enable User’ button

3. Create a recovery key. If you’re running Yosemite or later versions, your iCloud account can be used to unlock the disk and reset the password. On Mavericks and earlier, the recovery key can be stored with Apple by giving a security question with three answers.

Encrypting a Hard Drive in Linux

There are several different Linux distributions and several different ways of encrypting a hard drive in Linux. The easiest way is to encrypt the hard drive while your chosen distribution is being installed. Most popular Linux distributions, like Fedora, Debian, openSuse, Ubuntu, and Mint offer a full disk encryption option during installation.

Alternatively, you can also use TrueCrypt to encrypt your drive. To get a better idea about how to encrypt your hard drive with this tool, be sure to watch this video below:
