    I am going to be the HDD shill here and say they are better than SSDs, if you can forgo the speed you do not want in most cases. 5400 rpm is reliable.

      Depends on the IO requirements. For lots of reads and rare writes SSDs are usually better because they don’t have moving parts. HDDs are better for cold storage, as SSDs lose their charge over time.

        HDDs are not ideal for long-term cold storage either due to data rot, the magnetic charges on the hard drive platter that encode for 1 or 0 lose their magnetism over time. I’ve read that data rot can start to occur in as little as 1year if the data hasn’t been “refreshed” by powering the hard drive on and re-writing all the data.

        There are some archival-grade hard drives, but if you have data that you don’t want to store in the cloud and don’t access often an LTO drive is your best bet. You can get LTO tapes certified for 30+ years of cold storage, but the catch is that reading the data is super slow… and the tapes themselves are super flammable.

          Exactly, and with SSDs that can happen after a few weeks (!) of not turning the thing on. The only really reliable way is probably compressing and encoding it into literal granite.

          LTO tapes certified for 30+ years of cold storage

          Yeah, We had one of those we couldn’t read because some dumdum stored it sideways. The bits literally fall down, so you have to store LTO drives like this: | and not like this: _ ;)

          Cold storage is a science in and of itself, there’s college courses for archivists about storage formats. tl;da: use several media and copy it around with checksums every few years. Keep the data luke-warm, not ice-cold.

        HDDs have SMART, and that makes them.better than SSDs. SSDs all have proprietary diagnosis firmware, and all SSDs are backdoored by feds. Fuck SSDs with NSA and FVEY backdoors.

          Yeah, because SSDs also have SMART. The metrics are different.

            SMART is an open diagnosis technology for HDDs. There exists no such open tech for SSDs.

            Your logic equivalent would be calling Apple’s non standard Bluetooth with W1 chips the same as standard SBC/aptX Bluetooth for other TWS earbuds.

              SMART is an interface standard implemented by the HDD or SSD controller. The implementation is proprietary for almost all HDDs, too.
