Radi 5support will hit 5.x in future. Soeren Schmitt is working hard on it. But it may take some time till this happens. I own a Promise FastTrak S150 SX4 myself and i have killed my old raid5 array some days ago. i now use 4x 120gb as raid 0+1 with ataraid. It's sad, that Promise still advertises his FastTrak SX4 with future FreeBSD support. I spoke with an technician of Promise on Cebit 04. It's highly unlikely that Promise itself will release any bsd drivers. They have a linux-driver. I received a copy of it, too. Regrettably the Promise driver is only partly open-source. I provided Soeren with one copy, but he said it doesn't help him, as the relevant parts of the code are closed... so, at the moment i'm running CURRENT with raid 0+1 on my Promise SX4 till ataraid will handle raid5. Looking forward to that. Patrick
