I have an ASUS Prime B450M-A II motherboard and I'm currently using a Kingston SNVS/500G NVMe SSD as my main drive. I'm running low on storage and thinking about getting a Kingston NV3 1TB M.2 NVMe SSD. However, I want to confirm whether my motherboard can actually support it. I've read that it has only one NVMe slot, while the other M.2 slot supports only SATA. Is that accurate? If I can't use the Kingston NV3 in the second slot, would it be better to go for an M.2 SATA SSD or a 2.5" SATA SSD instead? Here's my setup:
- ASUS Prime B450M-A II
- Ryzen 7 5700G
- Kingston SNVS/500G SSD (M.2 NVMe)
- 16GB RAM

Yes, that's right. Your ASUS board only supports one NVMe drive, and since you're using a Ryzen processor, you'll need to opt for a 2.5" SATA SSD for additional storage. It's usually a better choice over an M.2 SATA SSD since they tend to be more versatile and can be used in different builds down the road.
Your motherboard indeed has only one M.2 NVMe slot that supports NVMe drives, and the second M.2 slot is limited to SATA only. So, your new Kingston NV3 wouldn't work in that second slot. If you're looking for extra storage, I'd recommend going for a 2.5" SATA SSD instead. They're generally easier to find and offer great compatibility for future upgrades.
If you have extra PCIe slots available, you could also consider using an adapter to install an NVMe SSD. Just keep in mind that those lower slots might only provide PCIe 2.0 x1 speeds, which would be slower than what a standard SATA drive offers.
