Really?
I would assume, even with the fastest drives you can buy, two (or more) of them in RAID0 will be faster. It's not like the single drive is saturating the sata bandwidth.
I'll admit it
is a hassle. If not done right, it can sometimes work out
worse performance wise -- never use the default strip/cluster size unless that tests as fastest. Even done right, it can be problematic. The integrated raid chipsets are far from perfect.
A little anecdote:
My raid benches were fine, all the scores show a huge boost to performance. The system runs fine. Everything seems to load faster, the system boots faster, I was happy. I still wanted more, but that included a hardware based raid card.
One of my favorite games is rFactor. I have a lot of mods and custom cars in it. At some point I noticed it was taking a very long time to load the game -- this was back when I was running a two drive striped raid. My other racing games were fine, GTR2 also has lots of mods and cars and loads in less than 30 seconds. Yet rFactor was taking like 2 minutes.
Since I hate waiting for
anything on a computer, and rFactor was basically the only game I was playing, I decided to throw two more HDs into the raid to maybe help it out loading. I already had the drives, and planned to mate them altogether anyway, so...
First thing was to back up the current state of my OS, as I didn't want to have to reinstall anything. Using another hard drive with it's own OS on it, I booted to that and archived the raid OS.
I then restored the archive to a single disk to test that it indeed worked, before blowing away the two drive raid and rebuilding it as a 4 drive raid.
It booted fine, everything seemed to be working ok with no errors or found new hardware crap. I decided to run it a few days like this to be sure. I launched rFactor and it
immediately popped up the spash screen and was in the game in less than 10 seconds!
WTF???
To make a long story short, all I can say is that (I think) the game itself accesses a system file (wmiprvse.exe) that the nvraid also accesses, and it was somehow conflicting. Only rFactor has a problem with my raid, and I can't really blame it on rFactor because it is as much nVidias fault. It could also be something I have messed up with my system -- I'd have to do a complete reinstall to be sure.
So what a
PITA that is! It's
still a work in progress, although not a priority. I can still run the game, although I moved to GTR Evolution when it came out. I'm in the middle of swapping cases because of a video card upgrade that won't fit when I have four drives mounted in my Silverstone TJ04. So I am back to a single drive, moved to my P180 to test the fit (cramped and fits but won't fit two in SLI), will be trying the four drive stripe again (maybe), and now,
screw the P180, I ordered a f'in Cooler Master HAF last week!
Sorry to appear to highjack this thread with my rant! Just sort of corraborating Charlie in the benefits of running a single drive, and while a stripped array may be faster in benchmarks it can rob you of huge time in troubleshooting problems down the road. You see, I had NO idea the slow load times were due to the raid, or HD... for all I knew, it was just the game and all the mods -- I added to the array to help it out. It was just fluke that I found it
was the raid (or at least related to it)!
