User feedback

We needed to dig quite a lot into problems that I've encountered just to find out that my k8s setup was using PersistentVolumeClass that was a combination of hard-drive with SSD cache that made the result performance vary.. (and might result in weaviate timeous )

You might want to note this here... since the only way how to discover this (if you won't use the standard HELM chart) is by analysing the helm chart it self.

Just add a note here:

that you need
spec:
storageClassName: premium-rwo

(at least for GCP... you might want to check it for AWS/Azure too)
