After Yosemite, RAID setup is extremely slow to copy, advice needed

[Richie3000]

After working my way through a number of kinks and finally getting a pretty-close-to-good installation of Yosemite on my GA-Z77-UD5H, I seem to have hit a wall.

My copying speeds to my RAID 0 setup is painfully slow (reading under 9mb/sec, writing under 3mb).

I've tried updating system definitions, but 3,1 seems most stable and none of the others had any positive effect. I've also tried installing the different USB/SATA kexts in MultiBeast 7.0.1. but to no avail. Lastly, I'd tried putting my old working RAID kexts from Mavericks into my Yosemite Extensions but that had no impact either.

Sorta dumbfounded at this point, not sure why my RAID speeds have slowed to a crawl. My other drives (both SSD and HDDs) all seem to read/write okay.

Any advice?

Sincerely,
