There is 64MB on the 6i and 192MB on the 642 controller. I wish the controllers had a "wrieback" enable option like the LSI MegaRAID adapters have. I have tried splitting the cache accelerator 25/75 75/25 0/100 100/0 but the results really did not improve.

I have heard that the 6i was actually decent but to avoid the 5i.
