That's a good way of explaining it and makes sense. I have 3x4TB WD Reds configured as an 8TB RAID 5 mdadm array in my Linux box. It's a sort of dumping grounds for backups/disk images, VMm images, etc. I would see initial write speeds of 150-200MB/sec but during large transfers moving 100's of GB, it would drop in write speed down to 50-60MB/sec. I thought it was a performance issue in the kernel or with mdadm and didn't bother to investigate further because I'm not a datacenter.
