I used a BT-958 fast/wide (but not differential) for some time and, with a fast disk got excellent results (as a single user of the system). And, that was with the old driver with no tagged queuing. Assuming the debug stage is past, the new driver: > > Very recently Justin T. Gibbs released a new device driver for the > Multimaster series, which includes the bt-958d.

My only complaint about the BT-9xx series is that they are kind of pricey - the reason I would tend to go with the Symbios-based boards is that they are usually cheaper. Granted, I don't have differential drivers or controller, so, I can't verify that that the -D version has no problems, but, I fail to see why trouble would be more likely than usual with the BT-958D. Anybody out there using the BT-958D?
