You do not say what RAID engine you use; which is very important of course.
If you use the chipset ports, you are running nVidia Mediashield RAID.
If you use the JMicron ports, you are using the JMicron JMB363 controller.
However, you state that you had three harddrives; 2 connected to nvidia, 1 to the jmicron. then you talk about a 3-drive RAID0. This is not possible if you connected the three disk to two different controllers; it cannot be one array.
The only situation where this would be possible would be with using software RAID.
So please explain to us how you setup this RAID first.
Generally, you should avoid the JMicron RAID drivers and never use them.
So you actually CAN boot into Windows, with a 3xRAID0 array on ports 0, 4, 5 (nvidia+jmicron) and it works without problems?
I'm kind of stunned, actually.
Though its certainly possible the nVidia RAID drivers use disks from the JMicron controller, i would expected they only used their own controllers.
Either way, what exactly is your question? If you are concerned about speed, download some benchmarks, screenshot them and post them here.
Good benchmarks are: AS SSD, CrystalDiskMark, HDTune Pro (File benchmark+Random Access).
As alread stated, I was getting a data transfer rate (read) using HD TUNE PRO, of 100-110MBPS, it doesnt drop down over the length of
the array (as its a raid) and is a straight line across rarely dropping below 100, but is that fast enough? I know the drives on there own can average speeds of 80-90, should I expect speeds like 240-270MBPS?
by the way, im assuming, as they are all under the control of the Nvidia RAID controller, it would be easy to move the drives to different ports, but I am not willing to do so without being 100% as rebuilding my OS isnt a fun task.
The HDTune Pro test has a tab named "File"; this benchmark will test on the filesystem instead; raise the test value to a higher value and run the benchmark. Now see if you get any different (higher) results.
yeah, I redid the tests, speeds in excess of 150MBPS, but only about 2/3 of the way through.
FINALLY GOT SOME SCREEN SHOTS FOR YOU
the last image, is obviously ALOT faster, and actually shows the dropoff at the end that I was looking for, this is using file sizes of 8Mb as appose to the default of 64kb
thanks, the burst speeds are also looking a bit slow, I was a bit worried when I saw the first test, with the speed being stable across the platter
to me that said there was a bottleneck somewhere in the controller or the RAID or somewhere in software, it ended up I simply couldnt work with peices
of 64kb, as appose to 8mb
Ill probably still considering moving the cables about, so they are all on the same controller though, any-thoughts on whether this is safe to do.
during boot, it shows the Nvidia Media Shield RAID screen, as it checks the RAID for health, so im taking a guess here saying that its most likely already under the
nvidia controller, but if I move the ports, how do I rebuild it such as it knows which drive is which. Is it smart enough to understand its looking at a RAID array it already built?
