AWS EKS Recommended Storage for Raft Integrated Storage

Hello All,
For an AWS EKS env, To use RAFT Integrated Storage, what is the best storage backend, Did anyone set this up using EFS, has anyone seen any issues with performance over a period of time?

Incase we choose EFS now and in future if we want to migrate to a different storage, will it be feasible without data loss?

Thanks in advance.
