Apple offers 5 GB of storage for free with any iCloud account, which they say should be fine for most users. However, if you've got more storage needs than that paltry 5 GB can handle, Apple has a few extra options on the table:
- 10 GB for $20 per year
- 20 GB for $40 per year
- 100 GB for $100 per year
Do note that these are in addition to your free 5GB of storage. In other words, if you opt to pay for 10 GB a year, you will actually have 15 GB total--the 10 GB that you are paying for, plus the original 5 GB that's included. If you're a developer with an iCloud account, you can purchase your additional space starting now.
