Dell PowerEdge R820 R720 storage upgrade Part 3 | How to upgrade with NVMe U.2 SSDs!

This video is the third and last in a series of 3 videos where I will show you how you can upgrade the storage subsystem of the Dell PowerEdge R820. And, since the R820 shares the chassis with the R720, this upgrade will also work with the PowerEdge R720. In this third part, I will take our upgrade path to the next level with NVMe PCIe SSDs in the R820 and R720 that originally only came with SAS-2 hardware. This upgrade kit is an official Dell kit that installs 4 NVMe U.2 SSDs in one of the 2.5" 8-bay drive cages with an NVMe backplane. We will install this kit, which includes a new drive cage, backplane, cables, and a PCIe switch expansion card. I will also re-run the same benchmarks I ran in the previous videos for comparison to show you what performance benefits can be gained with this NVMe upgrade. Along the way during this upgrade, I also discover some facts about this NVMe upgrade kit that I was not expecting.
