Backwards compatipable with PCIe Gen 3? I Have a Z390 Chipset motherboard now but going to upgrade but wanna get faster Drives to move stuff over when i can.

I used a PCIe to M.2 adapter card because my motherboard's (Asrock x370 Taichi) m.2 slots are incompatible with all PCIe Gen 4 SSD Due to a mismatch in pin definitions. My motherboard can support up to PCIe Gen 3. I was able to use this particular WD 4TB Blue SN5000 NVME which is PCIe Gen 4 rated; and not only is it backwards compatible to PCIe Gen 3, but it also compatible to as low as PCIe Gen 2. Hopes this helps.

Does this SSD come with any software for health checks and firmware updates?

Yes, the SSD includes the Western Digital Dashboard application for monitoring performance and available space.
