Today we are happy to announce performance upgrades to all newly provisioned services in all paid service tiers in Azure Search. For the exact same price, these upgraded Azure Search services have roughly double the compute power of the previous hardware configuration that backed Azure Search. Additionally, services in the Standard tier began using SSD storage under the hood, compared to HDD storage used previously.
With these service upgrades, we removed the document count limits from the Basic and Standard pricing tiers. This means that only storage limits are enforced in newly created Azure Search services. Depending on a scenario’s workload, these upgraded services may also benefit from faster indexing and querying performance at the same exact price points.
