M.2 NVME slots do not support multiple drives, look for PCIe x16 to multiple M.2 adapters.I've been looking around for a RAID controller that plugs into an NVME slot, hosts NVME drives, and is bootable but haven't found anything (at all, let alone bootable). Has anybody seen something like this?
An NVME slot doesn't have to support multiple drives for this to work. One of the features of a RAID controller is making multiple drives look like one drive.M.2 NVME slots do not support multiple drives, look for PCIe x16 to multiple M.2 adapters.
That's just some types of RAID but M.2 slot is actually a a micro PCIe x4 slot and has only 4 PCIE lines which a single NVME drive needs for full speed. RAID is just collection of individual drives in different configurations. I suppose you want RAID 0 which makes no practical sense with NVME drives. RAID 0 was useful for slow mechanical HDDs to speed them up as it makes drives work as one but with total number of platters and heads to do multiple reads and writes at same time. It doesn't speed up individual drives. If you use 2 or 4 NVMe SSDs on same PCIe x4 bus, speed drops by 2-4 times, negating RAID 0 usefulness. If you want just to make it to look just as one single drive capacity, there are SW solutions that can do that without losing any performance.An NVME slot doesn't have to support multiple drives for this to work.

How exactly do you imagine connecting multiple NVME drives to a single M.2 slot?I've been looking around for a RAID controller that plugs into an NVME slot, hosts NVME drives

Doesn't really matter in the context of the question. I'd just like to know about any NVME-to-NVME RAID controller cards.Why "RAID 1"?
What function do you want it to provide?
