Fix comment alignment here:

time sudo mkexfatfs -n "my_exFAT" -s 1 /dev/sda999     #   0.5 KiB (512 byte) 
                                                     #     clusters (10 sec)
time sudo mkexfatfs -n "my_exFAT" -s 8 /dev/sda999     #   4 KiB clusters (1.340 sec)
time sudo mkexfatfs -n "my_exFAT" -s 16 /dev/sda999    #   8 KiB clusters (0.698 sec) <=== WHAT I USE AND RECOMMEND: 8 KiB clusters
time sudo mkexfatfs -n "my_exFAT" -s 64 /dev/sda999    #  32 KiB clusters (0.230 sec)
time sudo mkexfatfs -n "my_exFAT" -s 256 /dev/sda999   # 128 KiB clusters (0.075 sec)
time sudo mkexfatfs -n "my_exFAT" -s 65536 /dev/sda999 # 32 MiB clusters (0.120 sec) [absolute max cluster size al

And fix all non-clickable URLs by putting <> around them to make them clickable (ex: in the References section at the end).
