Top-Selling External Hard Drives of 2021

External hard drives are the best and quickest solution for exhausted storage. They save you from the trouble of replacing your internal drive and transmitting and reorganizing all your data. They also serve as a great way of backing up your important files. There are, of course, virtual options for storing your data (such as Google Drive, iCloud, and OneDrive), but a tangible form is always better and offers much-needed comfort and ease (well, at least to me, it does so.). USB flash drives and portable SSDs also provide a backup option. However, though portable SSDs are more efficient in that they provide better security (against both data loss and physical damage) and transfer rates, external hard drives are a cheaper option that delivers almost the same level of performance.  

You should just be as careful when buying an external hard drive as you are when building your system. Here are the criteria for choosing the best one. 


The connection of a drive determines its transfer rates. While a majority of hard drives use the USB 3.0 connection, connections such as USB 3.2 Gen 2X2 Type and Thunderbolt 3 or 4 are more advanced and deliver higher speeds. However, you must find out the type of connectivity supported by the port on your device. The best external hard drives employ the USB-C port, which is the latest connectivity technology and supports fast transfer rates. 

Storage Capacity:

You should also consider the storage space that is needed. The larger the capacity is, the better a drive is. We recommend starting with 1TB of storage, since it provides enough space without being too expensive. It should suffice for most consumers. 

However, if you frequently work with huge files, such as HD videos and photos, you might consider purchasing one with more storage capacity. Fortunately, many external hard drives today provide terabytes (TB) of storage capacity for a relatively low price.


Reliability is another important factor. The physical strength of your drive and the data security it offers together determine the reliability of your drive. When looking for the finest external hard drive for your needs, make sure you pick one that can store all your data safely and withstand a physical shock under most circumstances. 

In short, the first step in selecting the finest external hard drive for your requirements is determining how much capacity you require. You don’t want to buy a disc that soon runs short of space, forcing you to purchase another one. However, you don’t want to overpay for the storage capacity that you’ll never use.

Furthermore, the finest external drives should be small enough to fit in your bag and have shock resistance to ensure that your data is protected while you are traveling.
