Well, in that case it depends on what you mean with "fast" in "fast
portable media" above. Writing at 3x isn't exactly what I'd call
"lightning fast". OTOH the kernel does a pretty good job at buffering
writes, which makes things quite acceptable for me.
Reading I'd indeed call fast, though.
So, unless you expect to be able to eject the disk 2 seconds after you
started copying a few 100 MB to it, you probably should give the
DVD-RAMs a try. The data safety might be worth it.
