Some external hard drives are built for people who might drop the drive or spill something on it, and others are meant more for sitting on a desk, inside and away from the weather. If you need a versatile external hard drive, look for one that's advertised as rugged or waterproof.
Another thing to think about is how much storage space you'll need. If you'll be keeping lots of HD videos on it, you need to get something with a lot more storage capacity than an external drive that'll just be used for hoarding documents for school.
Here's a general guideline you can follow, depending on what you'll be storing on the external HDD, to know how much space you might need:. Of course, choosing the right external hard drive is very much dependant on what you will use it for. While one person might have a music collection under GB, yours might be GB right now, with no plan in sight to stop download new files.
Maybe you even want to use the same drive for your new home movie collection or as a repository for your virtual machines. You have to be mindful of why you need the extra space and what you might put on the drive in the future. It's probably wise to go ahead and get a hard drive that's bigger than what you need right now. So, how do you know what kind of external hard drive you need to buy if you're not sure what you're going to put on it?
Start with a disk space analyzer tool to scan your current hard drive to see how much storage space is being occupied by the files you're planning on moving over to the new HDD, and then double that number to be safe. For example, if you find that your massive GB music collection is what you'll use your new drive for, assume it's 1, GB and buy yourself a 1—1. If you think you'll need just GB of storage for your movies, get a drive that can hold GB.
Similarly, while you might not need to have a USB 3. Preparing ahead of time will save you from having to upgrade to a 3. An external hard drive enclosure is a case that protects a hard drive. These cases come in multiple sizes and with mounting hardware and cords or adapters for connecting with a computer. Hard drive enclosures allow you to continue using an old hard drive when you replace a hard drive. Start external hard drive troubleshooting on Windows by double-checking that your USB ports and cables work.
If you don't detect USB issues, ensure that you formatted your hard drive according to the manufacturer's instructions. Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content. Create a personalised content profile. Measure ad performance. Although it is possible to remove the internal drive to replace it, it is easier for users to invest in a portable external hard drive to increase the capacity on their laptop or computer.
The main thing to remember is that an internal drive is built-in to your computer, whereas external drives are not. External hard drives are transferable, easy-to-use devices that can provide instant storage whenever you need to access it.
Using an external hard drive is as simple as just plugging one end of the cable into your computer and the other end into the drive.

Or perhaps you are wanting to back up important data? From data backups to portability, we have highlighted several reasons as to why you might need one:. Having an external hard drive will allow you to back up any of the data that you have on your computer or laptop. An accident could happen at any time, whether that includes you accidentally dropping your laptop during your commute to work, a power surge that can blow a fuse, a spilt drink, or a computer malfunction, there are loads of things that could happen to your computer when you least expect it.
Even though you will be able to back up most of your stuff via the cloud, there are numerous drawbacks to doing this, including possible monthly costs and data caps. When you back up all of the data on your computer onto an external hard drive, then you will always retain ownership of these photos, documents, and videos. A lot of people are going to think that this is still the case when they use services like Google Drive, however, when reading the fine print you will realise that this is not always the case.
When you upload all of this information into the servers, the company who owns the cloud service will be able to use your data in a variety of different ways for whatever reasons they want to.
Of course, Google will not be able to take your vacation photos and claim them as their own but they can use them for other purposes — all because you agreed to it when you decided to use their services. With an external drive, you have much more portability and access to everything on your computer even if you are not online. This is because the size of the external hard drives are a lot smaller than they used to be. The difference between an external hard drive and the hard drive in your computer is that an external drive is portable — you can disconnect it at any time and move it around, without losing the data inside.
External hard drives connect to your computer with a USB cord, and you can copy files to them like you would any other folder. Like flash drives, you can plug your external hard drive into any computer, and transfer your files freely. External hard drives can be used as supplemental storage — in other words, as an addition to the storage already on your computer. For example, if you have a large amount of high-definition photos and videos that are slowing your computer down, you can store them on your external hard drive instead.
External hard drives are also great for moving files between computers, regardless of their operating system. If you have an album on your PC that you want to share with your friend who has a Mac, you can save it on your external hard drive , plug the drive into your friend's computer, and then transfer it to them within a matter of minutes.
Most external hard drives can hold at least one terabyte 1 TB of data — this equals gigabytes GB , or 1,, megabytes MB. To put it into perspective, the most expensive iPhone on the market right now only holds GB — just about half a terabyte.
And the average photo taken by a smartphone is around 2 MB. An external hard drive can hold documents, various forms of media, software, and applications.
Essentially, if you have a file on your computer, it can be copied to an external hard drive. As noted, many users have started using cloud storage services like Google Drive , Dropbox, iCloud, and others.
The advantage that cloud storage has is convenience — you can access your files from any computer without special hardware. A hard drive is a computer component that holds data. Every computer needs at least one hard drive to store its operating system , programs and user information. This drive usually is internal, or built into the computer, but as computer systems have evolved and different needs, threats and circumstances have arisen, external hard drives have become more popular.
External hard drives usually are used in addition to internal hard drives in order to store more data. They also allow the user to put sensitive, confidential or otherwise important information on them, then disconnect them and store them in secure locations.
