Addressing hardware checklist critical feedback (#1080)

Browse Source 
We're getting a lot of repeated requests during
inbounds on sizing VMs specifically.

Our baremetal and K8s checklists are slightly generic to this and imply
a baseline that may be uncommon within a virtualized context

This attempts to bring together a slightly wider band while emphasizing
that our high-watermark is intended for high performance, while the low
watermark is a bare minimum.

@ -177,6 +179,7 @@ Persistent Volumes
MinIO can use any Kubernetes :kube-docs:`Persistent Volume (PV) <concepts/storage/persistent-volumes>` that supports the :kube-docs:`ReadWriteOnce <concepts/storage/persistent-volumes/#access-modes>` access mode.
MinIO's consistency guarantees require the exclusive storage access that ``ReadWriteOnce`` provides.
Additionally, MinIO recommends setting a reclaim policy of ``Retain`` for the PVC :kube-docs:`StorageClass <concepts/storage/storage-classes>`.
Where possible, configure the Storage Class, CSI, or other provisioner underlying the PV to format volumes as XFS to ensure best performance.
For Kubernetes clusters where nodes have Direct Attached Storage, MinIO strongly recommends using the `DirectPV CSI driver <https://min.io/directpv?ref=docs>`__.
DirectPV provides a distributed persistent volume manager that can discover, format, mount, schedule, and monitor drives across Kubernetes nodes.
