Ripping/Burning 2 DVD's at once is slow

I have 2 DVD drives and tried ripping 2 DVDs at once with Decrypter and they both go at the same speed of 5.5x or so. If I pause one the other jumps to full speed of 10x+. I

They are both on the same IDE cable, if I were to get 1 Sata drive would they both go full speed?

Comp specs:
E6600 Core 2 Duo
Asus P5W DH Deluxe
2x1GB DDR2-800
GeForce 7600GS
74GB Raptor (8M Cache)
BenQ DW 1655

Slowing is due to the sharing of the same IDE channel. If you get a s-ata drive, be sure that controllers in your mainboard supports optical drives. There are many complaints about s-ata controllers not supporting optical drives

In other words, if you use rip to two different hard disks, then you will get 10x speed for ripping each movie.My hdd’s are sata, my optical drives are each on their own ide channel as master.
