I got these parts today and did some speed benchmarks. They matched the advertised speeds very close being, slightly under. I found that running in Raid does not seem to benefit me in terms of speed. This could be due to maxing out the slot capabilities. (my best guess) The thing i do like is seeing all my storage under one drive though. These drives are very noticeably faster than the last SATA drives.
I got 90 to 110 Mbps from a standard hybrid SATA SSD drive to a SATA M.2 or NVME M.2. slow no matter what.
I then tried SATAM.2 to NVME PCIE, I got 350-450 Steady mbps on a manual transfer.
Last i installed the 2 NVME and booted them via Hardware Raid0 in Asus Bios.
The windows install time was around exactly 5 to 6 minutes from a flash USB.
Once i installed and updated the drivers of this NVME Raid0 config, I didn't have any other NVME to manually transfer to so I ran a CrystalDisk Benchmark.
