Sorry to disagree with you there, but when it comes to EMC at least, that's 
not the case.  A few years ago I found once you fill the write cache (I 
think it was 1GB), performance drops significantly, such that a Sparc 20 - 
SSA100 - VXVM combination performed better.  That had the EMC techs running 
in circles, then they claimed that my test wasn't fair (vxbench) because it 
wasn't a real-world simulation.
