disk burn in testing

[Mike Lovell]

does anyone have good recommendations as to some tools or utilities to 
use for exercising or burning in new hard disks? where i work, we buy *a 
lot* of disks and currently use a utility called thrash [1]. we just 
have it do a couple million random writes to the disk. but i could use 
some other tools to test the disks in different ways as well to get a 
better idea if the disk is going to hold up. i've thought about using 
bonnie++ or iozone as well. what you any of you use, if anything? thx.
