Depends on what you consider 'too slow'. I just benchmarked an 8 drive 
software RAID6 (8 x 1.5 TByte Seagate drives) on a PCI-X card (Areca 
ARC-1120 configured for JBOD operation) at 196 megabytes/second 
sustained sequential write and 420 megabytes/second sustained sequential 
read with bonnie++ on a Supermicro PDSMi board.

Just how fast do you need?
