 In below example, we ask MinIO Operator to create a Tenant yaml with 4 nodes, 16 volumes, and 16 Ti total raw capacity (4 volumes of 1 Ti per node). This means you need to have 4 PVs of 1Ti each per node, with a total of 4 nodes, before attempting to create the MinIO tenant.
 
-We recommend [direct CSI driver](https://github.com/minio/operator/blob/master/docs/using-direct-csi.md) to create PVs.
+Since MinIO has built-in erasure-code support for high-availability and data protection, we recommend the following CSI drivers for high-performance and scalability:

+- [Local PV](https://kubernetes.io/docs/concepts/storage/volumes/#local)
+- [OpenEBS Local PV](https://docs.openebs.io/docs/next/localpv.html)
+- [vSAN Direct](https://blogs.vmware.com/virtualblocks/2020/09/15/whats-new-in-vsan-7-update-1/)
+
+We recommend _against_ PVs or CSI drivers which use network-attached storage, as network latency reduces performance compared to local disks.
