    The 2.5" NVMe drives have been available for 2 or 3 years now. They are significantly cheaper than SAS SSD (although often faster), but don't expect consumer-like prices either. Expect ~1$/GB for the write-intensive models (Intel DC P4600, Micron 9100MAX, etc) and 0.50$-0.70$/GB for read-intensive models (Intel DC P3520, DC P4500).

    The DC P4600 will probably be the fastest drive for the money when it will be available in several weeks.

    If you plan to purchase one, be careful as most of them are available in both U.2 (2.5") and PCI-E (HHHL) form factors.

    I probably was not following the enterprise drives. What controller are they connected to or are certain billboards needed?

    As a starting point, take a look here. There is even an adapter that can plug into the m.2 slot which allows you to run a cable to a 2.5" NVMe SSD. I'm only aware of enterprise drives being available in a 2.5" size with NVMe connectors.

    If you're willing to pay through the nose, everything can be manufactured.

    U.2 on the desktop just doesn't make a lot of sense. One can get quite large M.2 SSDs or just go straight to storage on a PCIe card.

    You're forgetting the NVMe hot-swap use case. This is exactly what we had and needed in our lab from a Dell R730 rack-mount systems. There is demand for manufacturing 2.5" NVMe SSDs that aren't special cases.

    I'd argue that rack-mount systems aren't desktops.

    Are there 4GB M.2 cards yet? That may be enough if they work on a removable.

    I think the widths are the same but some are longer. 4TB is enough for large project in progress.

    You can put them in desktop systems. Lunar has atypical requirements so it requires procuring enterprise level equipment.

    I want a 4TB drive with more than 550 MB/sec. It's not that weird, is it?

    550MB/sec at what block size? No it's not weird.

    probably 4kB random write, 32 queue depth.

    No, the que depth realistically should be low. Higher numbers inflate the IPOPS.

    I'm not all that complicated. I just want ~4TB with performance similar to the 2TB SSDs like the 960 Prod and better reliability.

    Buy this drive and this adapter. Follow the instructions in this video to know how to install it.

    Finally, you must absolutely click on that link.
    Asta la vista, baby.

    Thanks. What is the warranty service situation for Intel SSD? Is there any way to determine if a seller and product are under USA warranty?

    You'd have to research that. If you don't want to bother with researching warranty eligibility, buy it from CDW for $100 more.

    Both sites list the same manufacturing part number SSDPE2KX040T701...how is it different? CDW has been around forever and usually interfaces with businesses. I haven't bought anything from them in a long time because they're often not the cheapest price for any given product. They have a 1-800 phone number you could call and ask.

    CDW has been around for decades, I can remember getting their catalogs in the mail.

    I may be confused by the PCIe 3.1 part, which I thought meant the PCIe card style rather than U.2. My X99 only has PCIe 3.0 if that matters.
    I'd want to figure out how to automatically copy that to the NAS.

    Not really. I suppose it is for servers.
    I suppose the sustained writes/reads are nothing special if they only report the 4K random results.

    The 2TB MX300 is just too much for the old PSDs. They keep throwing errors on batteries or slowing down after a while.

    I'm evaluating a 2.5" Samsung SM1715 NVMe 1.6TB drive in my desktop. What does everyone typically use for software to gauge the performance of SSDs under windows these days? I tried the common one like CrystalDiskMark and Atto. Are there others people use?
