Which last longer? Traditional HDDS or Solid states?

    I think you have to consider reliability too. What percentage of WD10EALX-009BAD fails and what of TS1TSSD230S.

    For reliability you would be better off using a SSD. Less moving parts will lead to a lower fail rate.

    There's no one answer to that.

    SSDs vary. SLC, MLC, TLC all have different endurance. You can pay more and get more. But importantly SSDs wear out from writing data. Reading data is fine but writing slowly damages them.

    HDDs wear out with hours spun up / spin up/down cycles. Heat shortens their lives.

    You've linked laptop drives so impacts hurt HDDs only, but not always as g sensors can save them.

    HDDs die slowly, SSDs blow their brains out typically.


    Overall, do not trust either. They will all eventually fail.

    Never a truer word said. If you have critical data, save it in multiple places both onsite and offsite. Also, more often than not data loss is not caused by a faulty part but by a muppet deleting or overwriting. Make backups often and test them regularly.

    A lot of cheaper large capacity SSD's are TLC, three bits per cell which is great for capacity but it has the lowest write endurance. For maximum SSD endurance look for SLC, however capacity is normally lower on these.
    If your data is business critical, you should be looking at enterprise flash drives, typically costing many times more than consumer SSD's but they are designed for 24/7 use.

    If you want performance you should be looking at nvme (and not the cheap stuff either) but even if you buy consumer level nvme its very quick:
