There are huge difference between what various cloud storage providers charge for storage space.
What makes things particularly confusing is that most services list their price plans and options completely differently to one another. Some list prices in dollars, others in pounds; some show charges by the month, others by the year.
All of this makes it maddeningly difficult to compare cloud storage price plans. That's why we've done the hard work for you.
Cloud storage prices compared
In the table below, we compare the annual charges for the most popular cloud storage services:
The easiest point of comparison is to look at the average cost per Gigabyte, and this is where there are some huge differences in what one cloud storage provider charges compared to another.
By this measure, DropBox's average of 62p per GB absolutely dwarves the 5p per GB charged by PC World's KnowHow cloud storage.
Microsoft's SkyDrive cloud storage is half the price of Google Drive when you look at the average cost per GB, and SugarSync's cloud storage turns out to be the most expensive service of the group.
If you're looking for a large amount of cloud storage, there's a massive difference between paying £50 a year for a terabyte of storage with PC World KnowHow, and £375 a year for the same amount of storage with Google Drive.
