to end this threat, I did:

# dd if=/dev/zero of=/dev/da0 bs=64k count=1
# newfs_msdos /dev/da0
# mount -t msdosfs /dev/da0 /mnt
# time cat file file file > /mnt/big
cat: stdout: File too large
0.276u 19.421s 14:36.63 2.2%    11+1180k 33887+65536io 0pf+0w

# df -kh /mnt
Filesystem    Size    Used   Avail Capacity  Mounted on
/dev/da0      7.5G    4.0G    3.5G    53%    /mnt

i.e. it writes the maximal file size of 4G in FAT32 and 3.5G are left as
free;

the write speed is
4294963200 in 14:36.63 minutes, i.e. 4902926 per sec;
