I have a collection of very good, and fast, random number gererators. I would be happy to make such a device, if it would be useful. But I don't want to go do the work only to have it ignored because the current RNG's are "good enough".
Responses??

Hallo,
as I have problems with bad blocks on a harddisk, I find it usefull to write random data to the disk to probe that. However the speed of /dev/urandom doesn't match the write speed of modern harddisks at all: elektron:/mnt1/home> time dd if=/dev/urandom of=/dev/null bs=1k count=1k 1024+0 records in 1024+0 records out 0.000u 4.040s 0:04.08 99.0% 0+0k 0+0io 42pf+0w That's about 250 kByte/sec. This is with a Pentium 100
So I would like to see a fast (possibly much mor predictable) random generator device (/dev/fandom), running with perhaps 5 MBytes/sec or better above. Is that feasable? -- Uwe Bonnes bon@elektron.ikp.physik.th-darmstadt.de
