Dell R310 - does SAS6/iR work ok?

[Graham Allan]

Prepurchase check... I know the SAS 6/iR disk controller has been 
supported since OpenBSD 4.3 or but I saw some reports of write 
performance issues (due to disabling cache). Does it work ok in 5.0?

Seems like my choices on the R310 are:
onboard SATA - not available as option with hotswap drives (not 
essential but handy)
PERC H200 - uses one of the PCIe slots, want these for other devices
SAS 6/iR - uses custom internal slot, should work with mpi driver
Thanks,

Graham
