please stop this bullshit, especially OFF-LIST
Fortunately you do not decide about it.
i do not sell them and i am not uneducated
The wording they use ("everyone do this", "because it is enterprise") just proves that most of them are people that should not even touch a computer
look in the mirror after your off-list explanations why
i am talking both about your off-list and on-list conversation in which you prove all your "knowledge" is advert based.
Words like "mainstream", "enterprise", etc. are just marketing words, and should not be used in technical discussion having no meaning. Using them prooves lack of real knowledge, and that's what you exactly did.
Saying to me - a regular massive user of cheap ATA/SATA drive in production since 14 years - that "nobody" use them in production is just funny!
But OK - you at least plan disaster recovery. Rare event. Your clients after paying huge money to get high complexity and low performance, AT LEAST will not loose data.
