(Links below) Other than my swap getting messed up because it didn't use labels (who knew about swaplabel but didn't tell me? ;-) ) the adapter and drive are in the machine and working fine. Unfortunately the performance isn't what I might have hoped for. Both hdparm & bonnie++ are reporting numbers in the 200MB/S range rather then the 400-500MB/S range that I might have hoped for. The machine is PCIx-2 based according to its specs. I'm currently just using a single large partition & ext3. I didn't do anything special in fdisk so the partition might not be aligned as best it could be. I don't know. I'm wondering what sort of experience folks have had trying to get performance numbers anywhere close to these specs?
