64 or 60 appears to slow it down a bit (2.5MiB/s becomes 2.2MiB/s).
Thanks. So it's not just a "power of 2" issue.
I wonder if it is related to the size of an "erase" block (which I read
are usually 64K, 128K, or 256K)? When writing is slow, there may be
lots of read/alter/rewrites happening, with extra wear on the flash.
