What are the Benefits of An External Hard Drive?

In the modern world, our computers are our lifelines. We use them for everything from streaming Netflix and Hulu to paying bills to keeping track of essential documents and working remotely.

In short, if your computer crashes, you’re out of luck.

Rather than stress about the fact that your computer could crash at any moment, you could back up your files instead.

Some people prefer to use Cloud-based storage—uploading files through the internet to an external server—while others feel safer with external hard drives.

Unlike Cloud-based storage, external drives are physical devices.

You can use them to access your files whenever you want, including during any Internet outages.

Plus, you’re not trusting your data to some third party that could quite easily suffer from a data breach, compromising your data in the process.

Why Do You Need an External Hard Drive?

If you’re an academic, digital creative, or you rely on your computer for programs, apps, and storage, you know the importance of having convenient access to your files at a moment’s notice.

If your computer gets lost, is in the shop, broken, or riddled with viruses, can you do your job?

If the answer is no, an external drive is an investment you’ll never regret.

In the case of computers that are getting on in their years, one of the biggest benefits of an external hard drive lots of additional storage without any fiddling around inside the case.

You can transfer all those big (or old) files from your internal hard drive, and plonk them on an external storage device instead.

Most people have no much clutter they have on their internal drives.

External hard drives also have tons of convenience by way of portability.

If you need to transfer files from one computer to another or travel without your PC, external hard drives plug into any computer and give you instant access to your files wherever you go.

You can also store a copy of all your valuable files in another physical location, like a deposit box, for example.

Basically, if you value your personal data then you need an external storage solution of some kind.

Are External Hard Drives Faster Than Internal Drives?

The short answer to this is “Nope”, simply because any external device on a PC will be connected via a USB port.

A typical and relatively modern internal drive transfers data at around 3.0Gbps (gigabits per second).

Then compare this to a device connected to a USB 2.0 port transferring data at 60MBps (megabytes per second) and you’ll see that an internal drive runs at roughly 8x the speed of any external hard drives.

Even USB 3.0 connections top out at 5Gbps vs. a SATA III powering along at 6Gbps, and it’s highly unlikely that your USB 3.0 connection can sustain that level of file transfer for more than short bursts.

Owning an external drive won’t make your computer run faster.

But it does allow you to own a portable, affordable and secure way of storing your data – and data transfer speeds are improving all the time.

Wear and Tear
