Re: Meanwhile, ssd marches on relentlessly
That's a very good point, and my understanding is that SSD heat scales pretty linearly with capacity, while HDD scales with number of platters, so it's a less direct relationship. And, of course, there's the sipndown option.
(My server is in the attic at home, and I've had to spin up drives when I've felt they've got too cold. About 8 degrees Celcius is a trigger to perform a RAID check.)
