    I doubt it. SSDs are subject to quantuum tunneling. This means if you don’t power up an SSD once in 2-5 years, your data is gone. HDDs have no such qualms. So long as they still spin, there’s your data and when they no longer do, you still have the heads inside.

    So you have a use case that SSDs will never replace, cold data storage. I use them for my cold offsite back ups.

      You’re wrong. HDD need about as much frequently powering up as SSD, because the magnetization gets weaker.

        Here’s a copy paste from superuser that will hopefully show you that what you said is incorrect in a way i find expresses my thoughts exactly

        Magnetic Field Breakdown

        Most sources state that permanent magnets lose their magnetic field strength at a rate of 1% per year. Assuming this is valid, after ~69 years, we can assume that half of the sectors in a hard drive would be corrupted (since they all lost half of their strength by this time). Obviously, this is quite a long time, but this risk is easily mitigated - simply re-write the data to the drive. How frequently you need to do this depends on the following two issues (I also go over this in my conclusion).

      Nothing in this article is talking about cold storage. And if we are talking about cold storage, as others gave pointed out, HHDs are also not a great solution. LTO (magnetic tape) is the industry standard for a good reason!

        Tape storage is the gold standard but it’s just not realistically applicable to low scale operations or personal data storage usage. Proper long term storage HDDs do exist and are perfectly adequate to the job as i specified above and i can attest this from personal experience.
