Legacy Filestore service tiers

Filestore legacy service tiers include the following:

  • Standard / Basic HDD
  • Premium / Basic SSD

When creating new instances, use Zonal or Regional service tiers. You can still use the already existing High scale SSD instances.

Basic HDD and Basic SSD

Basic tier Filestore instances are suitable for file sharing, software development, and use with GKE workloads. You can choose either HDD or SSD for storing data, with SSD offering greater performance at a higher cost.

Basic HDD instances have a performance increase when the provisioned capacity exceeds 10 TiB. The performance of basic SSD instances is fixed regardless of the provisioned capacity.

* The number of files listed is an indication of the maximum number of supported connections to small or empty files. The number of supported file connections decreases as file size increases. While no practical limit exists across service tiers, instance performance may be delayed when supporting a large number of files.

† Basic HDD (on GKE) refers to Basic HDD instances with a minimum capacity of 100 GiB provisioned with the Filestore CSI driver. Basic HDD instances with capacity lower than 1 TiB consume 1 TiB of quota.
