Welcome to PCIe 4.0 Storage
The last piece of the puzzle to make this platform get up and go is storage. I have plenty of PCIe NVMe M.2s around my lab, but with the kit I recieved a Corsair MP600 which is their newest PCIe 4.0 SSD based on the M.2 2280 form factor.
The only manufacturer that I know of which is currently offering PCIe 4.0 NVMe controllers is Phison which this drive is powered by, so assume any drives you buy now or relatively soon will be a Phison E16
The MP600 has claimed Read and write speeds reaching to the 5GB/s range. So we wanted to try it out.
Well, I have had many truly fast drives including 970 Pro, etc. this one just blew them all away hitting sequential of exactly 5GB/s. Now do keep in mind that unless you are writing large files back and forth from two of these drives you likely won’t get that speed very often, but it’s nice to know you have it. However, if you wanted to save some bucks, you could also slide in any PCIe/NVMe drive that is not PCIe 4.0 and it would work just fine albeit at their respective nominal speeds.
