Sorry it was 15MB/sec but thats still not very good. I spoke to a guy somewhere in asia and him and his friend (they worked for a large company forgot the name now) conducted some benchmarktests that show exactly the same as mine so i guess its just the speed that this array can do. To my luck we use this array for storage now and not so much for serverbackend diskcapacity. > I have heard horror stories about IDE raid when discs actualy die.

The thing is we will never know since the promisearray dosnt tell use much. > At least it sounds like the guy knew what he was talking about... yes indeed but still i was stunned when i heard what the solution was. Im use to work with 1-class serverhardware and ive never done anything like this before. -- Venlig hilsen/Kind regards Thomas Kirk ARKENA thomas(at)arkena(dot)com Http://www.arkena.com BOFH excuse #112: The monitor is plugged into the serial port -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
