Buffering to Disk?

1516 bytes

    Anyone that has extended experience with the amiga hardware know
the optimum size of a buffer to write with?
I am using the following: 

    write(fd,buf,i);  /* where i is returned from read(fd,buf,4096); */

So that for the most part, I am writing with 4096 byte blocks, 
but I get a few gronks every now and then. 4096 is however, one of the
one's that gronks the least.  I figure there is probably an internal
buffer of some sort that if filled exactly might reduce gronking and
searching to a minimum.  No?

Note: I am also assuming that write() is going to do this most
efficently, next to direct trackdisk twiddling.   Is this a valid
assumption?  (however, which, if anyone has some simple source on how
to trackdisk write, that they want to send...  feel free.)
