I'm testing/evaluating the Adaptec 52445 RAID controller. After having problems with drives being kicked out, I have standardized on Seagate 7200.11 750GB drives. I am now playing with the online capacity expansion feature of the controller. I started with a 4 drive, RAID6 array in optimal condition and told the controller to expand it to a 5 drive array (adding one additional drive). The rebuild has been running now for about 24 hours and it is 26% complete. So at this speed it would be on the order of ~4 days to expand the array. I could find no benchmarks for array expansion time so I am wondering if any other 52445 owners can tell me if this is normal, or slow.
