I have a sever with PCI Express 2.0 x8. The backplane in my SAS expanders support 12GBps SAS. Is it possible to get a M1215 (or comparable) SAS card and get 12GBps speeds with PCI express 2.0?

For 26 drives. 24 on one channel to the SAS expander and 2 to a SAS->SATA breakout.

Handle is 'bad' word. What kind of speed am I looking at? Will I even get close to topping the 6GB/s speed ?
