If connecting to miniSAS HD on motherboard, the backplane for upper bay will support U.2 ssd drive and nvme ssd.  SAS drives will not work.
No SSD or HDD work in upper bays on Dell T5820. They are connected to mini sas on MBO. I'm wondering if a SAS SSD or a SAS HDD would work there? Thanks in advance for the answers!
T5820, drives in upper bays?
