The storage capacity of PolarDB is automatically scaled out or in based on the amount of the stored data. You do not need to manually specify the storage capacity. You are charged for only the storage that you use. We recommend that you purchase PolarDB storage plans if you require a large storage capacity to store a large amount of data. This reduces the storage costs.

Prices of storage plans and discounts
If you need to store a large amount of data, such as 1,000 GB of data or more, storage plans are more cost-effective than the pay-as-you-go billing method. Larger discounts are offered for the storage plans that provide higher storage capacities.
