Dell PV220S poor performance

I have PV-220S connected with Perc 3/DC to the PE 6450 server with 1GB RAM,
1xP3 700MHz CPU, running Win2k Adv. Server. PV is filled with 14 10krpm 73GB
harddisks and on the backplane there are three 18GB hdds. On both channels
there are RAID 5 logical disks. Performance of both logical disks are poor -
read about 5-6MB/s. I upgraded the PV220S firmware, perc firmware, windows
2000 perc driver and array manager, but perfoormance didn't grow. What's the
problem? What is the bottleneck in this system?
