External hard drives are storage devices that are used to store and access data. Unlike their internal counterparts, external hard drives are encased in a protective shell that prevents any physical activity from damaging any stored information. They are used typically to create more storage space on a computer’s internal drive by storing valuable data from your computer securely. An external drive enables users to backup crucial and sensitive information, then disconnect and store it in secure locations.
External hard drives are very useful devices that can save you from the disaster of losing your files to harmful malware and device shutdown. A reliable external drive will keep your files and preserve them for as long as you need.

What are the Things to consider when choosing external hard drives?
To store your data securely, you need to know that the external hard drive you choose is capable of handling the functions you require it for. These are a few things you should check before making your choice, considering these would help you to choose the best external hard drive.
Storage size
Before going ahead to buy your new hard drive you need to first evaluate how much storage space you need. New external hard drives usually range in storage capacity (from 250 Gigabytes to several terabytes). You don’t want to be in a situation where you end up purchasing an external hard drive that does not have up to the required amount of space.
Examine your files and documents. The hard drive you would need should be able to store all your PDFs, photos, songs, and videos and still have a good deal of storage leftover from additional data. When choosing your external hard drive, one of the worst mistakes you can make is to get one that does not have enough storage capacity to save your data.
Portability
One major difference between external hard drives and internal hard drives is that external hard drives are portable and can function with multiple devices. You need to consider if your hard drive will be sitting next to a desktop for much of its life, or if it will go on trips with you along with your laptop.
If your plans for your new hard drive do not involve you moving around so much then hard drive size, weight, and probably overall design aren't important to you. On the other hand, if you’re going to be traveling or taking it along with you wherever you go then, weight may be an issue.
You should make sure that that your hard drive isn’t so heavy, consider the size and weight of your other laptop accessories that you also have to carry around with you. You should also consider the drive’s design. The smaller and flatter the drive, the easier the drive will be to pack.
Connectivity
External hard drives can function with several different connections like USB, USB Type C, eSATA, Firewire, and Thunderbolt. Each of these ports offers you a specific read and write speed, so you need to consider this before you purchase your drive. For example, USB type C offers 10 Gps of transfer speed, equivalent to double the speed on offer from USB 3.0. Another mode of transfer that is available is the wireless kind of connection. Whatever style you choose, ensure that you choose one that offers a fast-enough performance, as your particular needs require.
Read and Write speed
An external hard drive’s read speed is essentially how long it takes to download files from it. Write speed is how much time it takes to save something to the drive. These kinds of drives are very appropriate if you want to load or transfer lots of large video files. Pricy hard drives will usually offer zappy speeds of 400 MB per second or better. Cheaper hard drives have less read/write speed, around 100 to 150 MB per second, and work quite well for average daily use.
Which type of external hard drive is best – Hard drive vs SSD?
There are two types of external hard drive:
- Hard disk drives (HDD, also known as mechanical or traditional hard drives) or
- Solid-state drives (SSD).
SSD’s are lighter, faster, and less power-hungry than HDD drives but HDD drives are cheaper and more affordable. HDDs are also good for storing lots of data as they often have a high capacity.
If what you need is enough space to store large amounts of data within a reasonable price range, an HDD is the way to go. However, if speed is your top priority and you tend to need to move a lot of large files run programs off the drive an SSD will probably be most appropriate. Also, you can always store the data that you use less often on a high-capacity HDD, then use a smaller SSD for files that you need to access or move around often.
How much does an external hard drive cost?
The price of an external hard drive varies from anything between $70 to $350 for drives ranging from between 1 terabyte to 4 terabytes of size. Pricier and faster external drives can cost $350 or more – some very powerful huge hard drives can cost up to several hundred pounds.
You can also choose an external SSD. SSDs cost more for the storage space – a medium-sized SSD of around 1 TB will be significantly more expensive than a hard drive of a similar size.
