Congrats.  I think July was Hard Disk Month, since I and _several_ other
Amigoids I know got disks this month (also StarDrives).

Your performance figures are pretty good for the SFS; were you using the
StarDrive's FASTMODE to achieve these Diskperfa results?

I performed these experiments myself, and discovered that performance
improved noticeably if I _decreased_ the number of buffers- I currently
use 8.  I also noticed that the WRITE speeds could almost be doubled
by adjusting the interleave to 2 or 3.
