Re: Recommendation for Observatory PC
Please, where did I say -10C is extreme?toggle quoted messageShow quoted text
People should be aware what the rated temperature range is instead of
just cavalierly thinking I'll just use an SSD and it'll be fine.
10 C is a significant percentage of the rated temperature range ,and
there will be people here would like to operate a remote observatory in
temperatures even lower than -10 C.
Having worked on enterprise SSD firmware for quite a while I just wanted
people to be aware that there will be additional problems at the low end
of the temperature range. NAND flash is inherently unreliable and
requires a large number of error correction bits just to make the
technology usable. Modern (cheap) devices are using TLC or QLC NAND
which further exacerbates the problem as it reduces the read margin in
