Might be of interest to hear which SAS controller he has which doesn't
have the delay. There are several different controllers. E200 is the
cheap low end version available, both as PCI-E and module for servers
such as DL360 g5, DL380 g5, etc. It also comes in at least 2 versions
64MB Cache or 128MB Battery Backed Write Cache. 

Then there is the P400, again as PCI-E or module. Again with 2 cache 
versions, 256MB and 512MB with Battery Backed Write Cache.

And then there is the P600, which is PCIX, also in either 256MB or
512MB, both Battery Backed Write Cache.

The E200/64MB supports only RAID 0/1, E200/128MB does RAID 0/1/5, while
the P400 and P600 do RAID 0/1/5/6.
