# Product data caching

Nosto module caches the product data required for [product tagging](https://docs.nosto.com/techdocs/implementing-nosto/implement-on-your-website/manual-implementation/product-tagging) to speedup the load times of product pages. For [versions 4.0.0 < 5.0.0](https://docs.nosto.com/magento-2/features/product-data-caching/cachingimprovements) the product data is cached in database and for [version > 5.0.0](https://docs.nosto.com/magento-2/features/product-data-caching/built-in-caching) the module uses Magento's built-in caching.
