[comp.sys.mac.misc] Hard disk format interleave rates: Which is best?

bskendig@phoenix.Princeton.EDU (Brian Kendig) (09/19/90)

I have a Macintosh SE with 2.5Mb of memory.  When I got my hard drive
(a Tulin 50Mb built-it-yourself model; 50ms access time) two years
ago, I did a low-level format with a 1:3 interleave ratio (the default
of the formatting program).

Shortly thereafter, I learned that Mac Plusses work best with the 1:3
ratio.  The SE should be formatted at 1:2, and any higher models, at
1:1.  In the hopes that I'd occasionally use my hard drive with faster
machines, I reformatted my drive at 1:1 interleave, and noticed no
real difference in speed either way.

Since then, I've learned that going from 1:3 to 1:1 on a machine that
should be using 1:2 will actually slow down disk access!

My question is: If I reformat my hard drive at 1:2 interleave, will I
notice a marked increase in drive performance?  Or is it possible that
my machine is just being peppy and works fastest at 1:1?

Thanks for any info!
