I have a problem when installing Debian into my system My system is :

  1. Ryzen 5 3500
  2. MSI A320M-A PRO-MAX
  3. 2 Pcs of Western Digital Green 120GB SSD

I successfully create a RAID0 array configuration from BIOS. I followed motherboard's manual and add 2 identical SSD to RAID array.

  • I put Debian 10 installer (netinst) into my USB flashdrive
  • I boot to UEFI model
  • I add dmraid=true to the installer's menu when first boot
  • I try graphical or non-graphical installer, but there's no RAID array displayed when it asked for installation disk

I follow this manual https://wiki.debian.org/DebianInstaller/SataRaid but stuck at step #4 as there is no RAID volume detected in disk partitioner

I wouldn't trust the Hardware RAID. If that bios or motherboard ever failed, you're done. No recovery is possible. I would turn that off and go with a software type of RAID 10. That way you have a better chance of recovery from another source.

  • Fortunately, that's what I did last night. After stuck with this problem until mid-night I just install them with Software RAID. I just post it here so I can understand the problem better. Does Hw RAID that dangerous? Should it be faster than Software RAID?

    Hardware RAID IS FASTER because it's bare metal (So to speak) But, it's encoded and written with that propriety BIOS code for that specific RAID card. Unless you have a card EXACTLY like that one with the same BIOS and chip set version to the letter, You will still loose your data.
