Newbie question Two Intel P3600 Cards and RAID0

[Hiroyuki Sato]

Hello

I've succeed to create RAID0 with NVMe cards.
I executed following commands.

mdadm -C /dev/md/imsm0 /dev/nvme0n1 /dev/nvme1n1 -n 2 -e imsm -f
mdadm -C /dev/md0 /dev/md/imsm0 -n 2 -l 0 -c 128 -f

I followed this instruction.

Thanks.

P.S
Is this(mdadm) better than mtd_raid technorogy?
