The free option from iCloud is still 5GB, but the paid tiers have gotten a bit cheaper. The 20GB tier is 99 cents per month, and the 200GB tier is $3.99 per month. Those pricing changes actually happened back in June, but didn't get much press. Now, Apple has added in a 500GB option for $9.99 per month, and a 1TB option for $19.99 per month.
These prices actually pretty competitive overall. They trail behind options from Dropbox and Google Drive, which each offer 1TB tiers for $9.99 per month; but, Apple's prices are on par with Microsoft's OneDrive for the 200GB option, and better than Microsoft since OneDrive doesn't offer personal tiers above 200GB.
