Maybe use a 2.5" hard drive rather than an SSD? I can't think of any downsides for that purpose.

Assuming the car is actually used, an HDD would be subject to numerous physical stresses. Not exactly something HDDs like.

  • 2.5" hard drives are usually very robust when powered down. That comes from the age when they were expected to be used in laptops.

    • I was about to say “the age? You mean today” and realized 2.5” “laptop” hard drives aren’t really used in laptops anymore, even the low-end ones. Damn.

I had some immediate disgust thinking, "Moving parts? I am done with those!", but I think you are totally right. The 2.5" hard drive is likely to have better endurance in the poor environment and repeated thermal cycling of a car trunk.

Great idea. Hopefully I never have to try and read data from it.

  • Yep, an unpowered hard disk will be rated to something like 250 g's of shock and -40C to +70C temperatures. You could put it in a sealed pyrex container with some silica desiccant and some foam padding. Just keep it from sliding around loose, and it should physically survive anything but direct impact in a collision.

  • I’m not sure either would be great… An untested backup is a backup that may as well never have happened, make sure to test your backups!

    • This is very much a backup option of last resort. I maintain a real backup solution inside my house, but basically nowhere to keep something off-site. I do not consider the cloud acceptable. For my top tier priority data (low total file size), I really want something stored elsewhere.

      Given the non-ideal state of the car, I think the plan would be to just replace that drive on an annual basis.

    • It's still very valuable to have a reasonably robust backup even if you skimp on maintenance, though. No one's going to smash your hard disk with a hammer to punish you for being lazy. 90% isn't much different than 99% in an exceptional circumstance.
