Dennis,
I'm running NT4 SP6a on a dual 500 MHz PIII which has an Intel L440GX+
Server Board in it and it is just old enough to have an ATA33 interface.
I'm running the Intel ATA driver with an IBM 7,200 rpm ATA66 drive. The
"benchmark" test says for Block Size 65536 & 10 Mb that I have a read speed
of 13,111 kb/s and a write speed of 6,301 kb/s. I'm also running the
Winternals FAT32 driver which could be slowing down the write. What do you
get for a benchmark??
