Support is provided for using RAID across two M.2 NVMe SSDs or two SATA HDDs; you cannot use it if you have one M.2 NVMe SSD and one SATA HDD. Since the BN NUCs have one M.2 connector and one SATA connector, there are no "standard" configurations that can utilize RAID.

In that statement I very carefully qualified it using "standard". There are two non-standard (non-traditional) configurations that we can look at:

1. The M.2 connector does have support for using M.2 SATA SSDs. You could use an adapter that exposes the SATA lane to a standard SATA connector. Using this connector, you could connect a second HDD and then use RAID across the two SATA HDDs. Of course, this configuration is problematic as you must power both HDDs and there is no option for mounting two HDDs within the chassis.

2. Can you use RAID across one M.2 SATA SSD and one SATA HDD? In theory, yes, I think you can do this (at least for RAID1), but it would essentially be a waste of a SSD as all write operations will be at the speed of the slower HDD. It wouldn't surprise me if Intel blocked this combination for just that reason.

Clear as mud?

First of all, thank you very much for your response Scott! I really apreciate!

Sorry for my "mud" question! The NUC 7i3bnh Mainboard has only one M.2 PCIe/SSD Slot, but for a RAID 1 I need two M.2 Slots, right? How can put two M.2 SSD's in the NUC or how can I configure a RAID 1?

Thanks vor your answaer und kind regards.

Well, you simply can't use two M.2 devices in a BN NUC. Only the KY NUC (NUC7i7KYK), HN NUC (NUC8i7HNK) and HV NUC (NUC8i7HVK) support two M.2 devices.

My non-standard option 1 is the only way you can really do RAID on your BN NUC.

Sorry,
