Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Does the configuration software run on a non-dell system? I think I read somewhere the standard megaraid software won't control the dell versions of their parts, and you have to use a dell utility...
The H810 is one of their newest controllers, and I haven't personally used one. unfortunately, Dell has had a history of flip/flopping on supporting third party drives and then not and then supporting them again. I haven't seen any discussions on this card yet but the 700 series did support third party drives. Ask your friend to put a pair of non-dell sourced drives on the card and see if it supports creating a mirror.
