10 of the most affordable and reliable external hard drives of 2017


A hard drive is a great way to store huge amounts of data, far more than can be saved to most laptops or tablets. Sometimes you need the extra space that only a serious hard drive with terabytes of data will allow. 

Most laptops come with limited amounts of hard drive space, around 500GB or less, as they have solid state drives (SSD) inside. External hard drives are a great way to store or back up extra files, especially photos and videos. They can also be useful if you plan to do a lot of moving about and travelling while keeping your key files at the ready.

Here is everything you need to know when buying an external hard drive.

Hard drive brands

The most well-known hard drive brands include Seagate, Western Digital, Toshiba and Hitachi, while others such as Samsung, SanDisk and G-Tech also offer sleek and powerful external storage or solid state drives.

Storage capacity

Smaller hard drives have less than 1 TB of storage, not much more than you get in some laptops. These are smaller and more expensive but offer faster boot up for files and programs, ideal for use inside a slim and powerful ultrabook or notebook.

If you are a video editor or a photographer you may want several terabytes of storage. Fortunately, hard drive storage is not that expensive to add, and a 4 TB hard drive will set you back less than £200 from some brands.

Connectivity

Until recently, most hard drives connected with USB 2.0 or USB 3.0 connections, but now many are moving over to USB-C, which offers 10 Gps of transfer speed, equivalent to twice the speed on offer from USB 3.0. Other forms of connection include wireless transfer to the hard drive.

Reliability

Although hard drives tend to be pretty reliable there are few comprehensive reviews of how reliable drives are over a long time under strain, and nobody wants to loose years of cherished photos or videos.

Data from Backblaze shows Hitachi and Western Digital drives had some of the lowest failure rates last year, although these stats are largely limited to internal drives. To keep your files safe you may want to buy a more rugged hard drive.

Write and read speed

Read speed is essentially how long it takes to upload files from your head drive, while write speed is how long it takes to save something to the drive.

Most cheaper hard drives will have a fairly modest read/write speed of around 100 to 150 MB per second, not brilliant if you want to load or transfer lots of large video files.

Better hard drives will offer zippier speeds of 400 MB per second or better, although the prices will start to stack up at this range.

Price

The price of an external hard drive can vary from anything between £50 to £250 for medium sized drives of between 1 TB and 4 TB. More expensive, faster hard drives can cost £250 or more, while seriously large and powerful hard drives can cost several hundred pounds. 

You can also get external SSDs. These will cost more for the storage space, so a medium sized SSD of around 1 TB will be significantly more expensive than a hard drive of a similar size.

LaCie Porsche Design 1 TB

 Size: 1 TB

Need the next level in external storage? You will want to turn to a USB-C connected drive. This sleek design from LaCie features a USB-C port for faster connectivity, great if you use the new Macbook or Macbook Pro.

While this does make for theoretically faster data transfers, it can become an issue since the lone USB -C port on the Macbook means you will need an adapter to charge and use the drive at the same time. The USB-C also cannot alter the physical speed at which the LaCie writes or reads data, which is around 130 MB per second.
