Formatting a 3390 eckd image, it is clearly better to
use 4096 than 1024 byte blocks!
I formatted two 3390-3 volumes, one with 1K blocks and
one with 4K blocks. I then put ext2 filesystems of 1k
and 4bk blocks respectively. (SuSE SLES8 SP3)
I could get 1.2GB and 300,947 files of 1023 bytes or
less on the 4k block but I could only get .812 GB and
206,741 files on the 1k blocks!
Since I used from 0 to 1024byte files, all "small", 4k
blocks still got more and files on the back. If I had
used even bigger files, I would assume that 4k blocks
would look even better.
Here is a side by side comparison:
