Drobo S: What is the Maximal Capacity Drive Size?

Hi there,

I am using a couple of Drobo S drives. But unfortunately Drobo has removed the capacity calculator for the Drobo S from their web page. Now I have to buy larger drives and I can not find any information about the maximal capacity of supported drives. Can I use an 10 TB drive from Iron Wolf? Or is 4 TB the maximum size? What is the maximum drive size that is supported in a Drobo S?

How can I get informations about supported drives? Is there an calculator for deprecated Drobo machines?
