Best external hard drive

Which external hard drive is best?

Whether you are an information professional, a die-hard video gamer with more titles than space on your console or looking to preserve your family photos in a more durable form, external hard drives are an excellent way to increase your storage space. With a slim and powerful unit like the Western Digital My Passport Ultra at your disposal, you can save tremendous amounts of data to your heart's content, and rest assured, it will be well-protected outside of your PC.

What to know before you buy an external hard drive

Consider how much storage is needed

For those unfamiliar with exactly how much data is contained in a terabyte, a single TB possesses the same storage capacity as eight average smartphones with 128GB of internal storage. To clarify further, a terabyte can store up to 6.5 million digital document files like Microsoft Office and Adobe Acrobat, 250,000 photos taken by a 12-megapixel camera or a full 500 hours of HD video content (or roughly 250 average length movies).

The average netizen can probably get away with only a 4TB external hard drive. Still, if your internal hard drives are already full to bursting, it can be well worth spending the extra money on an 8TB unit to not run out of storage space for the foreseeable future.

HDD or SSD, which is better?

There are currently two major types of hard drives that are used in both internal and external applications, namely the hard disc drive and the solid-state drive. HHDs are mechanical in nature and rely upon moving parts like discs and arms to carry out operations while SSDs have no moving parts and instead use microchips to receive and transfer data.

If you are simply looking for a relatively inexpensive way to store files externally and keep them protected, you can likely get by with a conventional HDD unit. However, as the latest generation of external hard drives, SSDs offer the advantage of no moving parts, making them more reliable and resistant to external damage. Furthermore, SSD external hard drives tend to be smaller in size and can write data anywhere up to 15 times faster than HDDs can manage. 

What to look for in a quality external hard drive

This section should detail the primary features available in different models of this product, both fundamental features and optional features or upgrades. On average, expect to have three to six features. If there are a few key players synonymous with the product type (e.g., with smartphones, there is Apple vs. Android), cover their key points of differentiation.


Suppose you have any experience with typical external hard drives. In that case, you might be wondering how safe data stored on such devices can be if all you need to access it is a functioning computer with a compatible operating system and USB port. However, modern external hard drives now come equipped with security features like password protection backed up by 256-bit AES hardware encryption. As an encryption protocol adopted by the U.S. government and nations around the world, 256-bit AES hardware encryption protection abilities have been calculated.

Easy of use

Having the ability to plug and play with devices of all ages is key to transferring and preserving your data.


Let’s face it, many of us have dropped an expensive piece of electronic equipment harder than we’d like and hoped against hope that it would start up again without any issues. Of course, if your product has been designed to withstand a weight of up to one ton and is resistant to dust, rain, drops and shock, you can rest much easier if it happens to fall out of your computer bag. Not every hard drive can prevent such damage and destruction, so it is well worth considering purchasing a more durable unit for your needs.

How much you can expect to spend on an external hard drive

Depending on your desired features and how much memory you would like, an external hard drive can cost between $120-$220 and sometimes more.

Best external hard drive FAQ

How easy is it to connect my new hard drive to my PC or console?

A. Ideally, your external hard drive should be compatible with your OS and plug-and-play directly into a compatible USB port, though using these units as consoles will often require them to be reformatted before they can effectively store games.

What’s the best external hard drive to buy?

Given their overall superiority in data transfer speeds and load times, SSD is generally the superior choice, though HDDs are just fine for less sensitive data.
