I think it was 6.1 I ran > before updateing to 6.2-RELEASE It says about the same for my Areca ARC-1220 (PCI-express); it just simulates a SCSI controller; the bus bandwidth is not limited to 166MB/s since i got 880MB/s buffered burst speed and 400MB/s sequential write performance. Do you actually sense/measured a performance drop of any kind? 6.2-RELEASE does have another version of the Areca driver. - Veronica
