Encryption on a hard drive entails prohibiting access to the files on the drive by using mathematical functions that make the files unreadable.

As a result, you would need a key or a password to decrypt and read said files.

This is vital for people who want the benefit of confidentiality. For example, if you keep sensitive files on an encrypted hard drive and only you have the key/password, only you will be able to access the files and use the hard drive.

When to Encrypt

One of the many times you may need to encrypt your hard drive is when you have sensitive files on it.

As seen, when you do not want anyone seeing your family pictures or work documents, encrypting the drive will help with that.

Also, if you constantly have your hard drive in easily-accessible places or always leave it in plain sight, then implementing an encryption strategy should help you keep out unwanted snooping. This can be done in the office or at home.

If safety of personal and critical data is important to you, encryption cannot be understated.

The main benefit of encryption is for security. It is important to keep your data safe even when you feel like you have nothing to hide. That added layer of security can mean a lot.

While losing your drive may seem catastrophic, losing your personal information stored in the drive will be worse. Encryption helps circumvent this by making the files inaccessible unless your password is known or the key has been acquired as well.

At the same time, an encrypted hard drive will be much harder to steal if the would-be perpetrator already knows that the drive is encrypted. The person in whose hands the drive falls into will not be able to use it and that will give you some peace of mind.

Good Encryption Practice

For encryption to be effective, only you should have access to the drive. In other words, you should be the only one who knows the drive’s password or has the drive’s key if it’s a personal drive.

At the same time, make sure you’re using a strong password. Simple password or common words can be easy to find and be used to maliciously unlock your device, however, with a strong and uncommon password you’ll be safer.

Ultimately, you should also strive to take care of the hard drive by keeping it safe as well.

Final Words

If safety is your utmost concern, then here we looked at some of the best encrypted external hard drives from various type including SSD and HDD.

Encrypted hard drives are not as common and may charge a higher premium, but if you travel a lot with very critical documents and data, an encrypted hard drive is a useful investment.

This is also true for those who travel a lot and tend to store highly personally photos and videos in their hard drives.
