How to disable mdadm printing output on boot?

I'm trying to achieve silent boot without using a splash screen like Plymouth for a faster boot, and by following the Arch Wiki instructions I've managed to achieve it, except for one line that's printed every time:

myarray: clean, 908868/62234624 files, 148744957/248938496 blocks

I've looked into /etc/mdadm.conf, but didn't find anything about disabling output. I've also set

kernel.printk = 0 0 0 0

in sysctl.d, as well as setting the necessary kernel parameters:

root=/dev/md0 resume=/dev/md0 resume_offset=119576576 rw raid0.default_layout=2 quiet loglevel=0 udev.log_level=0 initrd=\intel-ucode.img initrd=\initramfs-linux-zen.img

but none of them have removed the RAID message. I've also looked for solutions that disable anything from being printed at all during boot, but haven't found any.

Pardon my ignorance, but how does silencing the boot messages speed up the boot process?

Edit: Never mind. I had a Roseanne Roseannadanna moment. Avoiding Plymouth will keep the boot process faster. Got it! :-P
