Cloud storage keeps your files on remote servers, so you need an internet connection to reach them. Without one, you cannot upload, download or open the files held in the cloud.
Because your files are stored online rather than on one machine, any internet-connected device can reach them — a library computer, a tablet at home, or a phone in a café. The service itself runs 24/7, so you can work whenever it suits you, as long as you have a connection.
It must be an internet connection, not just your home Wi-Fi: mobile data works too.
The speed and reliability of your connection affect how quickly files move. A fast, stable link transfers files in seconds, while a slow or patchy one makes large files frustrating to work with.
For example, a 500 MB folder of project files takes about 40 seconds to download on a 100 Mbps connection, but roughly 6 minutes 40 seconds on a 10 Mbps one. If the connection drops part-way through, the transfer may fail and you would have to start it again.
