Thanks for the info, although I do have a question. How are you
determining the through put? When I do a backup from Win95 and watch the
numbers on the screen I can't make the math work out (maybe it is some kind
of bizzare University math). As an example, Bytes Transfered = 31,919 KB,
Time = 00:20:50, Transfer rate = approx 1000KB/sec (I didn't write that
number down). Now if I do the math and divide the bytes transfered by the
number of seconds (31913 / 1250) I get 25.5 KB/sec! Somewhat short of the
reported 1000KB/sec. So what stupid thing did I do? What am I missing?
Also, assuming I still remember how to do math (questionable at the best of
times), a 10Mb(it)/sec Ethernet connection should only be able to transfer
1280KB(ytes)/sec. ie. 10(Mbits) * 1024 * 1024 = 10485760 bits/sec, then
divide by 8 for Bytes/sec = 1310720, then divide by 1024 for KB/sec =
1280KB/sec. If I did it right, how then do you achieve through put of
2048KB/sec?
On the plus side, if I can get at least 2MB/sec I figure it should only
take me approx 7 hrs to backup the 50GB. If I can get 4MB/sec, it should
only take 3.5 hrs.
Again thanks for your response, hope I haven't taken up too much of your time.
