As alright2565 already mentioned, sticking rand() in there doesn't add any benefit over a key + counter. Without rand() it would be something like SHA3-CTR -- it's not standardized…

Isn't it also similarly conceivable that if you write a predictable PRNG sequence such the outputs of Mersenne Twister you could also potentially extract patterns? Mersenne Twister…

If this is sufficient, then this matches what I said in the article. I wrote that if you don't care about what numbers you get, don't bother with xoroshiro or Mersenne Twister, jus…

If a predictable PRNG is sufficient for wiping disks, why do we care that the data is random at all? How about writing 0, 1, 2, ..., 255, 0, 1, 2, ... to consecutive bytes? Or -- g…

I can just about believe that this kind of scenario might be a very rare exception where the performance difference is relevant and you might want to do something else. Still, colo…

It's not true that I cherry-picked a slow PRNG for my 7 GB/s number. In fact I selected the second-fastest PRNG on that page (because it's popular)! The fastest one is 8 GB/s. PCG3…
