Are you saying you expect to be able to write 90 MB/s under ideal conditions, but that when you try to achieve that speed, you only write 1 MB/s? If so, that's very similar to symptoms I saw when working with some bad hardware a few years ago. The drives would inexplicably slow to a crawl during large transfers, yet the same drives worked perfectly when attached to different computers. I never did find the cause, since we got rid of those servers, but I suspected that either noisy power or vibration was causing the hard drives to frequently position the head inaccurately.
