    BIOS not showing my SSD M.2

    Could you clarify the problem? Does the system boot and work correctly? I can't tell if you are asking about why the drive isn't showing up, but still works and is seen by the OS and Kingston SSD manager, or if you are asking why it won't work in that notebook but it works in others. It looks like the BIOS sees it just fine in the boot order. Being a notebook, sometimes BIOS stuff gets quirky depending on how the OEM set it up.

    How is this Speed Possible?

    Was going to say the same thing. DRAM caching.

    fast drive array

    What server are you using specifically? DIY storage at the level you are talking about can go south very quickly. Are the hosts Linux, VMware, or Microsoft? Each one would have a different storage in mind.

    onboard raid controller giving me grief

    I don't know if I'd ever reccomend anyone use RAID0, especially network shares. In your setup are you using a BIOS controlled software RAID for all of this, or Windows Server software RAID?

    Intel SSD DC P4510 Review

    In our SR850 config, our NVMe drives were direct attached, not through a RAID card. These were to ports off the motherboard itself.

    FIO replay fails in case of size 0

    Does the run continue with showing those errors? Which version of FIO are you running? Looking for similar issues, someone did encounter a bug that was able to get patched. This was back in 2017, so many not completely related but still worth making sure you are running the latest. https://github.com/axboe/fio/issues/382
  7. Endurance is included in the specs on the TBW figure. On the controller, I'm not sure most people care one way or another on those anymore. It either performs well or it doesn't, you don't have a lot of options.I think it played a bigger role with SandForce years back where the workload you were using could be impacted by the controller, but for consumer products the 3rd party controller options aren't as variable.
  8. Spotted the problem on the BarraCuda review, one of the labels got pushed and swapped the results. We fixed it on that review with updated charts.

  10. Do you mean discoloration from pressure, or longer-term wear to the screen from frequent use?
  11. Zerto made several announcements at its annual conference, ZertoCON, regarding further updates, enhancements, and details of its roadmap. Among these announcements include the availability of a term-based licensing option via a subscription model for the Zerto IT Resilience Platform, integration with the VMware VAIO framework, enhancements to long-term repositories, as well as its latest development efforts for Zerto and Microsoft Azure.

  12. It sounds like you are dealing with an enclosure with a chipset not designed with the intention of dealing with a very large storage device inside of it. What hardware specifically is sitting between the host connection and the drive itself?

    EMC Unity Dedup ratio

    With DR solutions, I don't think you will see a huge difference between different technologies in terms of ratios. Most DR solutions come pretty close to one another in the grand scheme of things. Some that offer background as well as inline can help, but the big difference come into play with the performance overhead.

    super slow copy from ssd to other ssd

    What you are seeing is 100% expected. Its a QLC SSD, so once writes move outside of the write buffer, it will float at 40-50MB/s. Nothing is wrong, so nothing to really fix.
