After 5 years or suffering I found out how to make Linux not grind to screeching halt every time a write is being performed to Raspberry Pi SD card:

Put
#!/bin/bash
echo 128 > /sys/block/mmcblk0/queue/max_sectors_kb
echo bfq > /sys/block/mmcblk0/queue/scheduler

into /usr/local/bin/set_scheds.sh . Put

[Unit]
Description=Set Schedulers
After=sysinit.target
[Service]
Type=oneshot
ExecStart=/usr/local/bin/set_scheds.sh
RemainAfterExit=yes
[Install]
WantedBy=multi-user.target

into /etc/systemd/system/set_scheds.service . Do:
chmod a+x /usr/local/bin/set_scheds.sh
sudo systemctl daemon-reload
sudo systemctl enable set_scheds.service
sudo systemctl start set_scheds.service

I asked a friend full time employed as Linux kernel developer. He didn't know. He didn't know the max_sectors_kb is actually a parameter of the I/O scheduler. I discovered it accidentally. The doc is bad.

IMO horrible UX.

Trying to schedule a Communion visit with a daughter for her mother who has memory issues:
D: I’m busy this week, how about Monday?
Me: Nope, that’s a mandatory post-Easter day off.
D: Ok, I’m open any other day that week.
Me: Wednesday?
D: Busy….Friday?
Me: I’m off, but I can make 1:00 work.
D: Nope, busy

So much for being open any other day.
