On my DualRaidMachine running under WinXPPro I recognized that a copy of a 2GB-File from one raid to the other using the WinXP-copy achieved around 60 MB/s. Writing to the same raid with writeExact from the streams-module and null-filled buffers with varying sizes achieved only 4 MB/s. The cp-command from cygwin also achieved only 4 MB/s when copying the same 2 GB-file. Is there a special command that has to be used under WinXP? -manfred
