So this turns out to be a failing drive. SMART doesn't show it's failing, 
but the one that's failing defaults to having the write cache off, and 
turning it on doesn't change the speed.

I guess it's still usable, in a limited way - I can only write at 5 or 6 
MB/sec, but I can read at 200 MB/sec. Maybe I'll use it in an m68k Mac.

Also, the autoconfigure works, but the forcing of root FS status didn't 
because I was testing it on a system that already had a RAIDframe with 
forced root. However, it still doesn't work on aarch64, but I'll recheck 
this after trying Jared's boot.cfg support.

Thanks, Greg, Michael and Edgar. I learned something :) I am still curious 
about whether I was seeing both good read and write speeds because writes 
weren't going to both drives. I suppose I assumed that all writes would go 
to both drives even while reconstructing, but I suppose that only happens 
when the writes are inside of the area which has already been 
reconstructed, yes?
