Same problem with raid >1T, Still took 24 hr if I recall. When the array was 3 x 300gig almost the same time as 4 x 250 gig. Don't think the 300 vs 320 made much difference. Ram cache was running at default. One thing that was rather odd on the setups >1T was that the server went through a complete resync every time the unit was shut down and restarted. But don't recall the finer details.
