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.
I purchased the Highpoint 4322 just last week and its been running fine with my HP SAS Expander via the SFF-8088 port. The 4322 only has two external SFF-8088 SAS ports so I cannot test linking via the internal SFF-8087 ports.
