As simple as the title suggests.

/dev/sda is a unit from /dev/md127 - RAID1 drive.

I'm currently running a test - started a smartctl -t long /dev/sda.

Afterwards, I started to copy files over WinSCP (SFTP) to the mounted mdadm array.

I didn't notice any performance drops, but I'm kind of not sure - not a system administrator, am just developing an automated system.

Is it safe to "use" (write/read) disk while the drive is undergoing a smartcheck? What can go wrong? Are there any drawbacks?

Yes, it is safe, as the checks do not modify anything on your disk and thus will not interfere with your normal usage (I happen to be researching the topic right now). I have managed servers with smart checks running and never had to worry about using the disks at the same time.
