swxcr weird behaviour?

Hi, managers!
I just setup a new AS 1000A 5/400 with an RAID Array 200 controller (i.e.
a Mylex 960), 3 channels, (2 in use) with 7 disks (3+4). The controller
has 32Mb memory and battery backup.

I setup all 7 disks in one raid5 set (yes, 7 is maybe a bit on the upper
edge, but I think it shouldn't a problem as r/w ratio is close to 100 %).

Then I setup a small (4Gb) logical drive in the set. It started off
normally, (i.e. all lights almost continously on) but at 80% the drives
blinked only 1-2 times/second. It took hours to complete. Later on I
setup 2 8Gb logical drives. Same behaviour.

So I wonder: is this normal? Will this degrade my raid set's performance?
Should I reconfigure?

Regards, Harald
