Can i buy m.2 to 5 sata with jmb585 and it will be recognize by bios ?
Or i can use m.2 to pcie4x with some raid controller ?
The sockets are intended to be used for M.2 NVMe and SATA SSDs. There is no guarantee that a card attempting to use the PCIe lanes for other purposes will be supported. If it doesn't work - and especially for older products like this - there is little chance that any issue identified will be addressed.
