Installation of the SSD went smoothly. Upon installation we discovered that the firmware was out of date, there was a newer version as Samsung Magician Software told us. The firmware version on our SSD when installed was 3B2QJXD7. When we ran Samsung Magician Software to update the firmware, it updated it to 4B2QJXD7. This is the version we used while testing.
In CrystalDiskInfo we can see information on the SSD below. We can see that the Samsung 990 PRO is running at PCIe 4.0 x4 and NVMe 2.0 and supports S.M.A.R.T., TRIM, and VolatileWriteCache.
