looking for a raid card that does 0+1

[cujo]

just picked up a highpoint rocket raid 3520 for my 4x500gb aaks drives as i'm out of sata ports on my mobo and i want to install an sata dvd burner. previously i had them in raid 0+1 though the mobo said raid 10 i'm sure it was 0+1 based on results with 3520. basically the 3520 only supports raid 10 and needless to say, write performance is dismal compared to what i was used to. so i've looked high and low at 3ware, highpoint, adaptec, and promise and i can't find one single pcie raid card that does 0+1. does anyone know of a good one for a reasonable price (less than $500)? preferably 8 port but i could live with only 4.
