Raid Performance - is it OK? (2 x WD Gold 4TB in RAID 0)

Hi,

I am not very sure is my raid setup ok for the hardware use and I am not very familiar with benchmarks, can someone help to read the benchmark below:

I use 2 x 4TB WD Gold in RAID0. Using the Intel controller in Asus Priome X299-Deluxe mainboard.

I expected 400 MB/s speed and the results from the first roll (Seq) is more than expected, but I am not sure in all the 4KiB marks.

I striped the ride from bios utility at 128 KB, and did format the disk in windows at 64kB unit size.

Are all the 4KiB results from the bottom 3 rolls OK for this ride and the hardware I use?

Please let me know, or if I need to re-format or build the RAID in BIOS again if necessary.

Thanks
