1TB of random data. Damn. I don't know where you're going to
be able to find an entropy source that can produce that much
data in a reasonable amount of time. Typical entropy sources in
Desktop OSes based on keystrokes and network packets can
probably only manage a few hundred bits/second best case.
Even a hardware solution like those in some chipsets can't do
more than about 100K bits/second.
If your motherboard has a hardware RNG that'll do 100Kbps,
you're looking at about 3.8 years to generate 1TB of random
data.
Of course it's possible the OP doesn't really require random
data...
