I have about 100gb and growing that is critical for my business. File size growth is slow, so it will be years and years before it even gets to 200gb.

I have multiple local copies and a copy in google drive, but I want to leave a hard drive at my mother-in-law’s house.

I only want 2.5 form factor or smaller as my mother-in-law will be carrying it here when she comes to visit us on the city.

I’m not sure what the recommendation is. I’m not a millionaire, I’m just freelance. So, I’d like to minimize cost.

    SSDs lose charge over time. Within a year, bitflips might occur. I recommend going with an HDD with a shockproof case.

    This ineo t2580 looks good but I can’t seem to find the maximum capacity. Try not to use HDDs over 12TB and you should be fine.

      Thanks, I was thinking about a 1tb my passport from western digital.

      I live in a third world country so my options are a bit limited.

      I’m not worried about her dropping the drive, I just don’t want to ask her to lug around a 3.5” drive.

      Are mechanical drive resistant to bit flips?

        Are mechanical drive resistant to bit flips?

        No, but they don’t lose charge over time, so bitflips are less likely if they lay around for a long time. However they are less resistant to mechanical failures, so it’s kind of a trade-off.

        If you use a sane backup software it should be able to just overwrite all the data making bitflips hardly relevant.

      If you avoid QLC drives, keep it at a reasonable temperature, and don’t use a drive that’s had a large number of write cycles, it will be fine for a year.

      I would definitely read everything on the disk yearly so the controller can detect any weak blocks and rewrite them though. A good way to read everything would be to take a checksum. You can then compare that to the previous checksum to make sure the files haven’t changed too.

      Mechanical drives have issues with long term storage as well. When hard drives get older, sometimes they will just refuse to spin up after sitting for a long time.

        Sounds reasonable. Maybe even use SLC, some enterprise grade SSDs still offer that.

          SLC drives would hold data for a very long time, but they are pretty much only available for industrial use now and come with an industrial price tag. Even MLC is going away, it’s no longer available in consumer grade drives and getting harder to find in enterprise grade drives.
