I suppose I'll update this thread as this continues and if anybody knows of a good site of technical support people that I could publicly post about this and look for solutions then let me know as I doubt any involved parties (Nvidia, Asus, WD, etc) will give a rats ass if I call complaining.
Brief Background:
M2N32 SLI Deluxe
Vista64bit and XP64bit --> started out as C: images from Ghost2003 FROM the raptor raid, now reside on the first and second partitions, respectively, of my first of 6 data disks. Thus, both of these needed the registry workaround I describe below since Windows is so cool with drive letters.
2x74GB raptors TRYING to get them raid0 and continue to run as my system disk which they have for the last 2 years. unfortunately I cannot pinpoint when the write speeds declined to the level they are at as I never really benchmarked them before and didn't notice how bad it was [hey, reads were fast.......ignorance is bliss] until recently when I was moving mad datas around for the introduction of a new TB.
I've got 2x74gb raptors and the write speed (SiSoft Sandra) when raided is completely messed up. Outside of raid (I've recently imaged and migrated my OS off of the raid to see what the hell was up and am running from a fully functional vista) the drives are again not perfect.
The 74gb raptors are of 2 different flavors, an older one 00NLR and a newer one 00FLA, or at least I'm pretty sure that that is their chronological order.
The 00NLR gets 65MB/s read and 33MB/s write and the 00FLA gets 56MB/s read and 71MB/s write. Odd to say the least but the 00NLR was used as a boot device on a previous system and as part of a raid for both Xp 64bit and vista 64bit and has been through some filesystem fuckups, etc so whatever, they are what they are. That said, their performance under raid is puzzling.
When raided together, the array achieves 100MB/s read and 15MB/s write.
When raided independently (2 raid 0s each with 1 of the drives) the 00FLA has basically the same performance and the 00NLR has a 1-2MB/s drop in read and a drop in write to NINE (9!!!!) MB/s. So, the write when they are raided together can be explained by the 00NLR being completely borked running just by itself under the raid. The Nvidia drivers (Mediashield, I'm currently using the ones with the nforce590 mobo drivers that nvidia has had up since last july [15.01] and I've tried a variety from the asus website [they are really cool about horribling mislableing and misrepresenting their downloads...like "chipset" drivers that contain just mediashield and different versions of the same components listed under completley different names!] with no change).
So as it stands, I have a useless array that I'm not restoring anything back to until I can get it to work. I understand that my drives are old and worn, but there is nothing diagnostically wrong with them, no bad sectors and no write fails or anything. I have a SNEAKING SUSPCION that this shit is all nvidia's doing...but I've tried everything short of drivercleanerpro which I doubt does anything...I uninstall cleanly everytime, etc. I've tried so many different driver versions that I just think they haven't got a working 64bit vista driver yet or something of that nature... I just want to achieve a minimum of 33 write on the raid (and if I fix the current problem I'm willing to bet it'll be even better and more like 55) so its worth using.
I'll have XP 64 up soon [im waiting on a valid XP 32 cd to download as my hacked one doesnt cut it for Barts PE so I can edit the registry from a PE environment and change HKEY_LOCAL_MACHINE\system\MountedDevices so XP doesnt hang at boot just like I had to do to migrate vista, GOTTA LOVE DRIVE LETTERS!] and will report back the speeds I get under XP.
I've been in drive hell for 3 days as that registry edit to deal with C: issues was fun fun fun and it certainly looks like I ain't leaving it anytime soon.
EDIT: Forget to mention that the write and read speeds perfectly correlate with what I see in Vista so its not a benchmark thing. Before I ever touched the raid while my OS was still on it it could not sustain greater than 10MB/s and often was much worse around 3.
