Is your desktop, laptop or smartphone chock-full of files? Has freeing up space become an increasingly pressing and persistent chore? Well, it could be time to harness external storage to help divvy the data load.
There are a range of options to choose from. However, it’s important to settle on storage that will complement your devices and how you use them.
USB flash drives and external hard drives are among the most commonly available forms of external storage. And they are designed for use with different types of host devices, be it a PC or mobile device. So, as an initial step, you need to consider which devices the storage will be paired with.
Meanwhile, in addition to storage capacity, it’s worthwhile weighing up a range of factors that will influence usability. These include
- Interface type (how the storage connects to a host device)
- Data transfer speeds
- Design and portability
- Operating system compatibility
External storage: key features to consider
Storage capacity is, of course, the headline feature when shopping around for a USB flash drive or external hard drive. However, beyond this, it’s important to consider how you’ll use the storage when assessing the range of additional features on offer.
Your requirements from your memory device will change in line with the data being stored and how you access it. This could be:
- Pairing fixed storage with your desktop
- Transferring files from your tablet to your laptop
- Integrating additional storage with your home entertainment system
Read on for some of the key features to keep in mind:
Storage capacity is commonly measured in GB (gigabytes) and TB (terabytes). External storage options range from small devices capable of holding a few GB to larger devices sporting TB capacities.
To put this into context, most file types (from smartphone photos and videos, to full-length HD movies) will range anywhere in size from a few MB (megabytes) up to a few GB:
- 1 GB = 1000MB
- 1 TB = 1000 GB, or 1,000,000 MB
A device with a few GB of storage will likely come in handy for storing and transferring files of limited size, such as word documents, pdfs and photos. Devices in the TB range are more of a long-term option, providing ample space for the bulk storage of larger files, such as movies and years of snaps from your phone.
How the external storage connects to your host device, the interface, is an important consideration, both in terms of compatibility and data transfer speeds.
USB is the most widely used interface. USB-A and the newer USB-C types are the most common forms of USB. While USB-A has long been used across a range of devices, USB-C has become an increasingly common feature of new-release devices.
Across both USB-A and USB-C devices, standard designations (such as USB 2.0 and USB 3.0) refer to data transfer rate capabilities (often measured as MB/s). USB standards are backwards compatible, and will operate at the speed of the slower standard being used.
Notably, the USB-C type (which features a smaller, slimmer design) has the potential to deliver far higher data transfer rates than USB-A.
From PCs to mobile devices, it is, of course, important to choose external storage that is compatible with your operating software. It’s certainly worthwhile confirming compatibility before making a purchase.
External storage devices are generally compatible with a range of operating systems. However, in some cases, compatibility could be an issue if you’re using an older operating system with a newer storage device, or vice versa.
Manufacturers will generally provide a list of the range of operating systems their devices are designed to work with.
External storage devices come in all shapes and sizes. But beyond design idiosyncrasies, it’s important to keep in mind how big they are, and how they’ll fit with your desktop work areas.
For instance, if you’re shopping around for a fixed desktop hard drive, the size of the model probably won’t be too much of an issue. So you may well be more open to considering an AC-powered hard drive (as opposed to a USB-powered plug-and-play hard drive).
However, if you’re constantly on the go and need your data at the ready – or need to regularly transfer files between computers – portability, durability and plug-and-play flexibility are more likely to be priority considerations.
Of course, always shop around and weigh up the respective specs and price tags on offer from different types of storage devices. Additional things to keep an eye out for include a good warranty length and any security or data back-up software that’s included.
Meanwhile, when it comes to the interface, keep in mind that adaptors and cables can provide for connections to different host devices. So you might need to buy some extra cables or adaptors.
USB flash drives
USB flash drives (also commonly referred to as memory sticks and thumb drives) have become a ubiquitous PC accessory over the years. They provide quick and easy storage in a pocket-sized package.
Available in all sorts of shapes and sizes, USB flash drives can pack a lot of storage capacity into a compact form. They’re a good choice if you’re looking for a portable, accessible back-up for your files.
USB flash drives are also one of the cheaper options. Prices for lower-storage models start under $10.

External hard drives
External hard drives should be a go-to device when storage capacity is a priority consideration. They are a good option if you’re looking to permanently store different types of media (such as photos, music and videos). Smaller USB-powered models also provide handy portability benefits.
Solid-state drives (SSDs) have emerged as a growing component of the wider external hard drive market, delivering speed and durability benefits over traditional hard drives, and could be a good choice if you’re more efficiency than storage-focused.
As a rule, traditional hard drives will provide greater value per dollar in terms of the storage capacity on offer, while SSDs deliver a step up when it comes to performance.
