How to choose an external hard drive

In 2021, classic hard drives are rapidly losing ground to SSDs. The same trend can be seen among external drives as well. But even now, the best external hard drives of 2021 have a number of advantages, the most important of which is price. Despite the decrease in the cost per conditional gigabyte of SSD, hard drives are still beyond competition in this indicator.


What do you need from a device that will often be taken on the road? A sturdy case, of course. Some models with a plastic casing, even from reputable manufacturers, cannot boast this, annoying users with creaks. Fully metal external hard drives are rare now, but you can find models with aluminum inserts. The most advanced hard drives have a rubberized casing and even water protection. Pay attention to whether the design allows you to disassemble the case and take out the hard drive, in case of breakage. Otherwise, a faulty connector will put an end to a perfectly serviceable drive.


There are several memory sizes on the market for the best 2021 external hard drives. The 512GB size is rare these days, with 1TB becoming the standard. If that’s not enough for you, there are 2, 3, or 4TB versions. Of course these are all 2.5″ hard drives. The large 3.5″ hard drives have practically disappeared from the market, not being able to compete because of their size and the need for additional power.

Connectivity and Speed

Today’s external drives use two USB interfaces for connection and several variations of connectors. Basically, the best 2021 external hard drives run on USB 3.0, which offers a maximum transfer speed of 120MB/s. Advanced models work with a version of USB 3.1 (aka Apple’s Thunderbolt 3), which, in theory, can deliver speeds of 1.2 GB/s. In practice, the hard drives themselves are not able to produce such figures and the speed rarely exceeds 200 MB/s. As for connectors, in most of the external drives used USB Type-B, which is an expanded version of microUSB. More and more often there are models with modern Type-C. And there are quite exotic drives with the usual large USB.

Reliability and warranty

It is believed that the best external hard drives 2021 remain more reliable means of storing information than solid-state drives, which have some limit of recorded data. But in reality, users encounter breakdowns. Most often they are not related to the hard drive itself, but to the connector and controller. A separate category of failures is related to the fall of the device during operation, because hard drives do not tolerate this. In any case, you should choose models with the least amount of negative reviews and the longest warranty.
