I am on a Widows 2000 box using the NTFS file system.
Both up to now suggested approaches as
- tee.exe (where I used the http://david.tribble.com/dos/tee.exe
DOS-port with redirecting stdout to NULL) and
- parallel copy (hoping caching does the job) are by far
slower than the consecutive copy:
single copy speed 12-15 MByte/s
which gives effectively
6-7 MByte/s,
tee.exe or twice copy in parallel
1-3 MByte/s.
Any other suggestions except writing an own
optimised version of tee.exe, because it is so
easy to come up with:
while(c=getchar()){fputc(c,fp1);fputc(c,fp2);}
?
Is there maybe a way to use a direct DMA
transfer to multiple target destinations
(I copy to drives connected via USB ports) ?
Can someone point me in the right direction?
