Too slow creating mdadm RAID1

[fpabreu]

Hi,

I bought a brand new SATA QUAD KIT for my Rasp PI 4B, and I get a very long time to create a RAID-1 2Tb, by the previson it will takes more then 24h

The two disks are also brand new:
2x 2.5" Seagate Barracuda 2TB 5400RPM 128MB SATA III - ST2000LM015

[setq]

Try the following:

echo 'dev.raid.speed_limit_min = 100000' | sudo tee -a /etc/sysctl.conf
sudo sysctl -p

Works like a charm!
