Apple added a new iCloud storage tier today, offering customers 2TB of data storage at a price of $25.99 per month in Canada. Apple now offers four iCloud storage tiers at prices that start at $1.29.
Since camera improvements could be one of the features coming to the iPhone 7 and the iPhone 7 Plus, and Desktop Sync in macOS Sierra, there are at least a couple reasons why Apple is introducing more storage space. A dual-lens camera, rumored for the iPhone 7 Plus, could potentially produce images that are much larger, requiring more space to store photos and videos with other iCloud files.
MacOS Sierra’s Desktop Sync synchronizes all files stored on the desktop and in the Documents folder of a Mac and they are automatically uploaded to iCloud to make them available across a wide range of devices.
Also, if the high-end iPhone models offer up to 256GB of storage, backing up your device would require you to increase your available iCloud storage space.
