RAID question on initial setup and testing

I'm fixing to do some benchmarks on my new RAID Array, but have a couple of questions.

1. When i run the benchmarks do i need to have anything (files, etc..) on the drives i'm testing? I would think so, otherwise, what would the benchmark be testing??

2. Also, my ARRAY shows up in my computer on XP as one drive as it should, but is this the only way to know if you setup it up right. I went into my RAID bios (Adaptec 3400s) and it says it's setup. The reason i guess i ask is that it didn't take anytime at all to do --just seemed to easy). Formatting NTFS was the only thing that took some time.


Thanks ahead of time.
 
The fact is that RAID setup is pretty easy. Aslong as you get the controler sees both of the drives it should not take more than a min. to setup if you know what it is asking for in the setup like. Mirror or Striping and what not. You can make sure the RAID driver is loaded (even though it is since it shows up as one drive) buy going to the windows device manager. The controller should come up as some sort of SCSI controller. You can also see it setup under Control Panel => Administrative tools => Computer management = "Storage" in the left "file type" listbox.
 
jonmullen,

Thanks for the answer. Would you happen to know the answer to the below question.

1. When i run the benchmarks do i need to have anything (files, etc..) on the drives(the raid) i'm testing? I would think so, otherwise, what would the benchmark be testing?? I'm trying to find out the optimum stripesize/clustersize for my setup and have read the only way to know is to test it out.

Thanks again

 
I have never run any benchmarks on an empty drive. I have however run benchmarks after a clean install. So if your OS files are on the drive then if should work. I guess if you setup is hd1=OS hd2(RAID)=Data and Data=Empty then I am not for sure what would happen. I guess you could try it. If for some or numbers you get like freakishly high than it probebly is not working on the other hand it might not be moving real data. For the Reads and what not it might just generate junk files, but to tell the truth I don't know. Heck the file system might even have enough data for it to benchmark. I would like to know what happens if you do benchmark a truly empty drive such that there is nothing on it. Not even an OS.
