Many people like to run SR with a single parity drive. This is dangerous becasue if a drive is close to dying, running 100% for a day or so could kill it.
So what if there was a "gnetle recovery" option? SR takes double the amount of time to recover the failed drive, but the drives run at half speed. Maybe recovery a percent then idle for a minute or two for the drives to cool down or something like that. Some idle time to prevent all of the drives running at 100% for a day or two.
Just an idea.

Frequently spinning up and down a dying drive is probably a bad choice regardless of what is causing the drive to die.
The only scenario where reading data slower could make a positive difference is if the disk issue is heat related. In all other scenarios it would make more sense to read the data as fast as possible.
And if there is any reason to suspect any kind of heat issue while attempting to recover data, then it is better to not attempt recovery until you have been able to improve cooling.
Personally I would still like an option to throttle speed in order to make sync or fix less noticable.

I agree spinning drives up an down isn't a good idea. I believe in leaving the drives running all the time for max reliability. What I'm suggesting is your last sentence; throttling speed or starting and stopping read and writing.
