I really couldn't care less about blocksizes, but it seems to be that
it's impossible to reach high LTO4 write-speeds with lower blocksizes;
tests show that >100MiB/s are not possible with blocksizes around 64KB
to 512KB (from memory), so: the bigger the blocksize, the higher the
writing speed.

I suppose this gets even more critical with LTO5 drives.
