RE: What is expected performance from H/W RAID 5?

Do you think the bottleneck could cause the sequential IO write speed to drop to as low as 1.5MB / Sec? If this is the case, it seems weird that many "High Performance" branded machines come with Hot Swap devices which can seat 6 drives each, intended for hardware RAID access... Regards, Matthe
