Re: Recommendation for Observatory PC

-10C is hardly extreme. Get ahold of yourself.

I would be careful assuming that an SSD is better than a hard drive
particularly in a very cold environment. While the SSD has no moving
parts, NAND flash erases and writes are more problematic at low
temperatures. If the data was written at a high temperature, data
retention at low temp will improve, however.

The NAND technology makes a difference too. A SLC (single layer cell),
more expensive device will operate more reliably over a larger range of
temperatures than a MLC or TLC device.

Manufacturers do make SSD's that are spec'ed to operate at much lower
temperatures (-30C or lower) for more extreme environments, but you'd
have to source it at Digikey or Mouser instead of some place like
Newegg. Because the SSD isn't the only consideration it would be best
to look for a complete PC which is designed to operate in extreme
