Perhaps that's not the end of this story, though. One of the Seagate support forum members who initially complained dropped us a line saying the new firmware negatively impacts performance. According to Nick, average read performance for his 1.5TB 'cuda was 105.8MB/s. With the new firmware, however, he claims read performance dipped to 86MB/s. Disabling write caching allegedly brought that figure back up to 101MB/s.
