we tried this with a Dell H200 (also LSI2008 based).
however, running some basic benchmarks, we saw no immediate difference
between IT and IR firmware.
so i'd like to know: what kind of performance improvement do you get,
and how did you measure it it?
IMO, flashing to IT firmware is mainly done to get the JBOD feature,
which most of the time lacks with IR.
ah, thanks for clarifying. not defining any raid set does the same thing
on the H200 (we have it in R515 with 14 disks, all seen by the OS).

thanks a lot

Based on searching I'd done previously I got the impression that

generally recommended avoiding it in favour of the higher specced H710
(LSI SAS2208 chipset).
Purely based on the controller chip it should be OK.
We are using Supermicro's with that chip and are happy about it.
( We have 2xSSD and 10x1TB disk)
Note that we are using a JBOD firmware, not sure if DELL provides that.
You can flash it with any firmware, our IBM controller uses firmware
from supermicro (because IBM doesn't provide IT FW for it)
I wouldn't use it for bunch of SSDs but for spinners performance is fine
