    1) How can I identify if a 2.5" HDD model is good for archiving? Is there a failure chart between the models? Or by sales batch and year of manufacture?

    I have Seagate ST500LM030, WD10JPVX-08JC3T5 and HGST HTS541010A99E662

    2) Is there much difference between 2.5" CMR HDD x 2.5" SMR HDD in terms of long-term data archiving?

    SMR is junk that no one should ever buy. Regardless of manufacturers' fiddling, conjuring up reality, nothing will change that.

    Not for the 2.5 inch. For 3.5 it runs backblaze statistics.

    As above only CMR and 3.5 inches

    In my experience, of the 2.5" drives, the Samsung (continued by seagate) st1000lm024 has been the most user resistant

    - no, it's too much work and too expensive for someone to do this really systematically and reliably.

    - of these it has the highest risk. The SMR, plus the disastrously resolved mechanics, should disqualify it from serious use, but this and similar models are often chosen because they are cheap.

    - yes - the primary risk factor is the two-level logical to physical address translation subsystem.

    Can you point out according to this key a specific type/model/series?, worth recommending.

    what model HDD 500gb 2.5" and 3.5" are very good for longtime archiving data?

    Added after 47 [minutes]:

    >>21398378 i not for me necessary some 500gb and little money

    None. Hdd disks are not designed for such purposes. For long-term archiving there are tapes, M-DISC boasts that 1000 years of their media is supposed to last.

    But if necessarily hdd then only us with a large number of disks and even its redundancy.

    2.5 is totally not used anywhere. The 3.5 smallest capacities are the 1TB series from my post above.

    Exactly, nothing to add, nothing to take away.

    Firstly, the phrase 'long-lasting' should be clarified.
    Personally, I own quite a few old HDDs that still work great.
    A few 500 Seagate from e.g. 2007, but also e.g. Samsung from 2004 or Maxtor 2007, 2004.
    By excellent I mean good sector access times and not just the absence of bad sectors.

    Currently, however, it is less and less profitable to archive data on a large number of smaller drives because the price of 1gb of these very capacious is similar to 500-1000gb of used from the Allegro.
    I do, however, praise them because they do more work and take up more space, but in the event that one of them dies, I do not lose a few TB, but, for example, 500gb.

    However, 3.5 inch drives need additional power supply and 2.5 inch can be connected to a computer with a cable for a few zlotys.

    As for the models, you should rather ask about the black list and choose the HDD which are not on it and after the purchase check its SMART and access times.
    And this should be done from time to time. This is all the more important if the HDD performs/loads files more slowly, e.g. thumbnails.

    ps. Seagate generally do not appeal to me if only because they do not show the entire SMART, but buying a (supposedly) new drive their advantage is an additional FARM system in addition to SMART.

    Is it possible to prevent the demagnetization of HDDs or is the demagnetization of HDDs an inevitable phenomenon caused by storage conditions (humidity and temperature of my room storage)?

    You already had that explained. There's no such process as HDD self-demagnetizing, and 2.5" drives are not good choice for long-term backups.

    Can you please stop feeding this troll? He's been asking the same thing over and over again since he started his forum career, he's some kind of paranoid person with a fixation on disks.

Topic summary

The discussion centers on identifying reliable 2.5" HDD models for long-term data archiving, comparing CMR (Conventional Magnetic Recording) and SMR (Shingled Magnetic Recording) technologies. Participants express strong skepticism towards SMR drives, labeling them as unsuitable for serious use due to higher failure risks and mechanical issues. Recommendations lean towards CMR drives, with specific models like the Samsung ST1000LM024 and various WD and Seagate models suggested for better reliability. The conversation also touches on the inadequacy of 2.5" drives for archiving compared to alternatives like tape storage and M-DISC, emphasizing the importance of checking SMART data and avoiding known problematic models. Additionally, the topic of HDD demagnetization is addressed, clarifying that self-demagnetization is not a concern for HDDs.
