Well, you're getting disk overloaded, which is the reason. Though, you shouldn't be (I don't and I've gone at 500 KB/s). is your disk heavily fragmented or something?

I saw that Disk Overload 100%, but what is it how does it cause the erratic bandwidth?

Nothing is on that drive except media downloads, its only a few months old, 150GB external, 79gb used, 69gb free.

Because it means that it's going faster than the disk can keep up with, so it throttles back the speeds until the disk catches up. Since 300 KB/s is pretty low, it leads me to believe the drive is heavily fragmented. Have you tried running a defrag or at least an analysis lately?

edit: didn't read, external. Is it USB1.1 or USB2.0? You might have to manually set a much larger cache for an external drive. Change diskio.write_queue_size to 8192 or something.

so the broadband transfers are too fast for the USB1, I guess thats good and bad news.

Is manually changing cache size value going to affect anything on the C-drive? Theres very little space left or RAM left on this old computer. Thanks!
