unless dos386 describes what program(s) he used on what hardware

just did exactly this (for command.com) COPY.
unfortunately performance remains the same.

for a single drive (that is able to read ~43 MB/sec), using
a copy buffer of 60K (Freecom default), copy performs
roughly identical, even if the filr is pre-created.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security 
threats, fraudulent activity, and more. Splunk takes this data and makes 
sense of it. IT sense. And common sense.
