"WD Red HDDs have for many years reliably powered home and small business NAS systems" Yes, the non SMR ones."

You are misleading the consumer and should have called it WD Pink, because the SMR drives are a totally different product.

"If you have purchased a WD Red drive, please call our customer care if you are experiencing performance or any other technical issues. We will have options for you. We are here to help."

Other than refunding or providing a replacement non-SMR drive without extra cost to the consumer are the only options.
