HA Yellow - how to determine if SSD is being used?

Just moved my HA from VirtualBox VM to brand new Yellow. I bought a Kingston NV2 NVMe PCIe 4.0 SSD 500G and installed it when I onboarded the HA. Can’t figure out if it’s running from the MMC or the SSD.

Also, is this SSD compatible?

Is there an easy way?

Thanks!
