An external hard drive considering the features the price, and ease of use would be the ideal option to pick from the trio if all you need extra storage for? is a single computer.
It also comes in handy if you need additional storage to carry large sets of data all the time.
They come in many different shapes and sizes, all portable ones iFixApple sell get power and data down the one cable.
With flash drives coming down by the day in price you even get UNBEATABLE performance at a GREAT price.
If you own just a single computer, you are better off with an external hard drive. However, if you own two or more computers, you should consider getting a network-Attached Storage device. This is because a NAS will connect to your (home or office) network and all computers connected to your router will have simultaneous access to data on the device. A NAS also allow you to add additional drives for further expansion and setup a RAID, this can provide improoved performance and redundancy which can allow 1 or even 2 drives to fail without you loosing any of your irreplaceable data.
if what you are looking for is extreme redundancy then cloud is your very best option, while the others offer increased storage and speed. If your priority is safety, cloud storage and a local single drive backup might be the best (but not the cheapest) choice. You can certainly just set up a RAID on your NAS (which makes two copies of each file), but that’s still not 100% insurance. Here’s a short list of things that have another opinion about your redundancy strategy:
House fire • Flooding • Theft • Power outage • Faulty house wiring • Bad power strip or surge protector • Pets damaging your wiring • Physical damage • EMP
Let’s make things clear. Cloud storage is renting up a space from a provider. You can imagine it as renting a space in several NAS devices standing somewhere in the world. however, if you have poor or unreliable internet speed then this may not be your best option.
