This suggests something is wrong with that device. Are all RAID0 disks internal? Or connected to external box?

Can you post lspci -v output from you L2000?

I noticed the slow down/speed up when I built the RAID0 on the B180 as well.

Can you try running two different dbench instances at the some time on two different disks?
