Uhm... sorry, scratch that. > > Block size does not seem to be a factor. I've tried 8k, 16k and 32k > > (over 32k doesn't work for some reason). I've just tried reading and writing on a Tandberg SLR7 which has a max. speed of 6 MB/s, using 5K blocks on tape. My testcase was a directory of 645 MB, full of source code (lots of small files). Using 10K blocks (-b20) for tar, I got roughly 850 KB/s on write and 1.25 MB/s on read. Using 1000K blocks (-b2000), I got 1.4MB/s on write and nearly the full 6 MB/s on read.
