• System used for testing:
  HP ML350 G5 quad CPU with 4GB RAM
  Four Seagate 15K.6 disks in raid0

• For benchmarking we used CrystalDisk and HDTune

• Please see CrystalDisk results below

Perc 6i Raid Controller	P400i Raid Controller

• As the size of the file gets smaller the HP card start performing better





• Now lets take a look at the results of HDTune

Perc 6i Raid Controller	P400i Raid Controller

• Conclusion

• Perc 6i performs much better when the files used for testing were large, once the file size was reduced P400i performed slightly better.
  P400i should perform better on the database servers but not by much.
  
  Perc6i card performs very well and we will perform our feature disk and raid tests with it.
