It's where your operating system, software, and other files are stored. In addition to your internal hard drive, it's often useful to have an external hard drive that plugs in via USB, helping you back up your files in case the original device fails. If you choose a wireless external hard drive, you'll have all the advantages of an external hard drive without having to plug the device into your desktop or laptop. Wireless hard drives are convenient, versatile, and offer a clean setup. Here's a look at how wireless external hard drives work, what they're used for, and some tips for buying one. Wireless hard drives work with Windows, Mac, and Linux computers as well as Android and iOS mobile devices. Vincent Huijgens / EyeEm, Getty Images What Is a Wireless External Hard Drive? A wireless external hard drive looks a lot like a regular external hard drive. It's a standard hard drive placed inside its own case, existing safely outside your computer. They need no cables or physical tethering to connect to your computer or device. All wireless external hard drives come with a power cable, while others may include extra cables for connecting to a USB socket or for plugging into your Wi-Fi router via an ethernet cable. Some wireless external hard drives create their own network so it can work completely independently from your wireless network. A wireless hard drive's features depend on its model and manufacturer, such as Western Digital or Seagate. Wireless external hard drives vary in size, with some more portable than others. Consider your portability and space needs before purchasing one. While a traditional external hard drive is limited because it requires you to physically plug it into your computer or another device, a wireless external hard drive is a lot more flexible. Place it anywhere in your home (provided it's connected to your Wi-Fi network) and access it from all your devices. Like the best technology, it's the kind of thing you can install and not think too much about again. How Does a Wireless Hard Drive Work? The hard drive part of a wireless external hard drive works exactly the same as the hard drive inside your computer. The way it's connected is the difference. Wireless hard drives connect either directly to your Wi-Fi network (such as by plugging it into your router) or by creating its own network for you to join with your devices. In many cases, it takes only a matter of minutes to set up a wireless hard drive. Join it with other devices as you would a regular Wi-Fi network, such as by entering a password. It'll even show up as a separate hard drive on your PC or Mac so you can easily browse your files, just as if it were right next to you. Some of the latest wireless external hard drives also have NFC technology built-in. Touch your NFC-supported smartphone or tablet to the hard drive and immediately browse your files without having to join the Wi-Fi network. Why Use a Wireless External Hard Drive? A hard-wired solution such as a conventional external hard drive may be cheaper than a wireless external hard drive, but that doesn't mean it's better. There are many reasons why a wireless external hard drive might be a good option for your situation. Flexibility If you have a laptop you move around the home often, you don't have to worry about taking the external hard drive around with you. The wireless external hard drive will stay connected at all times, and you won't have to keep plugging it in and unplugging it. Worldwide Use Many wireless external hard drives are accessible from any Wi-Fi network, meaning you could be located somewhere else in the world, away from home, and log into your hard drive to access key files. It's like your own personal cloud service, but without worrying the company will close down or leak your data. Make sure your security settings are up to date and safe so strangers can't easily access your data. Streaming Capabilities Most wireless external hard drives don't just offer networking capabilities, they also offer ways to stream your media files across devices. Depending on your home setup, you could stream all your family photos to a smart photo frame, stream your iTunes library, or store all your home movies and access them from any device. Multiple Computers Can Use It Like anything else on your wireless network, multiple people can use your wireless external hard drive at the same time. Back up files while a family member is streaming a movie, for example. It's Ideal for a Small Business Many large businesses use NAS devices to keep their data safe, yet accessible by all the computers within the office. Such units serve as a central location for all your data, but they're often expensive and complex. For a small business, a wireless external hard drive is a good, inexpensive alternative that's easy to set up and use. It'll keep the company data safe while facilitating collaboration. Wireless Hard Drive Buying Tips When looking to buy a wireless hard drive, think about your unique home or business needs. Capacity Make sure you buy a wireless external hard drive with a larger capacity than you need. Plan ahead and future-proof how much space you might require. Needs Consider your unique situation. Do you need a wireless external hard drive for music files or backups of important documents? Your particular requirements will affect the capacity and wireless speeds you'll need. Features While buying a larger capacity is always worthwhile, don't buy a hard drive with more features than you require. For example, you won't need streaming capabilities and apps when you're planning only on regularly backing up your laptop's hard drive. Security Remember to set up the security features correctly when you first bring home your wireless external hard drive. The main disadvantage of a wireless external hard drive is the risk of someone else accessing it. With a strong password, this is far less likely to occur.
