Is 'google Kubernetes standard disks' quickly enough for Cassandra?

4/9/2019

I'm creating a Cassandra cluster in Google Cloud Platform in Kubernetes.

I saw that google provides different type of disks, the question is: "Is 'google Kubernetes standard disks' quickly enough for Cassandra?", or I should to change to SSD disks?

I think that the best solution is Local SSD disks, but I don't know if is an overkill.

Anyone have experience with this?

According to cassandra's documentation, they recommend

local ephemeral SSDs

Though, you won't notice significant performance degradation running on regional/zonal SSD's.

It is more important to allocate commitlogs (commitlog_directory) and data dictionary (data_file_directories) to the separate physical drives.
