I'm gonna claim that this card isn't aimed at enterprise use-cases that need this kind of service. I'd put it along the lines of "nearline SAS" HDDs, aimed at non-critical applications where you care more about bulk capacity than reliability. Relatedly, M.2 SSDs are inherently slower than the same pile of silicon in an U.2/2.5" form factor — the power/heat budget is noticeably lower.
