MBytes of course. Most of my drives are 10k Cheetahs. The manufacturer 
lists these as 38.4-63.9 MB/s formatted, 5.1 ms access time. I am usually 
getting between 51-55 MB/s read/write. This will also depend on the kernel 
you're using. Some of them are better than the others. As far as the 
effective networking speed goes, I am getting 92 Mb/s on eepro100 cards and 
~800 Mb/s on eepro1000 fiber cards through a GB switch using one of the 
simple benchmarks such as ttcp. I don't know anything about IDE disks and 
IDE arrays since I am not using them.
