The Raspberry Pi 5 has a PCIe port that works well with the Radxa Penta SATA HAT.

Great howto BUT you might want to add that the speedtest command is destructive to the existing filesystem and you will lose it. Luckily I had just created my filesystems and didn't have any data on them.

Nondestructive speedtest command

(
mountpath="/srv/dev-disk-by-uuid-YOUR-UUID-HERE"

mountpoint -q "$mountpath" || {
echo "Drive is not mounted. Test cancelled."
exit 1
}

testfile=$(sudo mktemp "$mountpath/.speedtest.XXXXXX") || exit 1
trap 'sudo rm -- "$testfile"' EXIT

echo "WRITE SPEED:"
sudo dd if=/dev/zero of="$testfile" bs=16M count=256 oflag=direct conv=fsync status=progress &&
{
echo "READ SPEED:"
sudo dd if="$testfile" of=/dev/null bs=16M iflag=direct status=progress
}
)
