    So micron has come out with some really much more affordable high capacity SSDs recently. For example, if you are in the market for a 7.68 TB SATA based Drive, I’ve seen this drive for under $1000:

    https://www.amazon.com/gp/product/B07JQ2F2WG/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1


    However, they have recently released drives with even greater capacity, and more importantly nvme read and write speeds. Even the 15 TB drive is now under $3300, which makes it compelling if still somewhat expensive:

    https://www.guru3d.com/news-story/1...-offers-850k-iops-and-75-petabyte-writes.html

    https://www.cdw.com/product/micron-9300-pro-solid-state-drive-15.36-tb-u.2-pcie-nvme/5529945


    This drive uses what looks like a 2.5” drive form factor, but is called a U.2 form factor with a PCIe Gen3 x 4 NVMe interface, and is Capable of 3500 MB per second read and write speeds.

    So the question is, is there a controller card that can make use of the drive’s interface and form factor that works in 5,1 cMP? Any pointers will be appreciated!

    Yes, High Point has a SSD7101-A equivalent card with U2 connections, SSD7120 - should work nicely with MP5,1, it's just another form factor of the SSD7101-A/SSD7102 cards and no fan!

    Wow Thanks Alex! So I guess there is some kind of U.2 cable to connect the drive to that card. Do you know if there is a U.2 bracket adapter that would hold the U.2 drive in one of the 3.5” bays? Would the normal 2.5” adapter brackets also work for the U.2 drive?

    I have a similar setup in a client Mac Pro, SSD7120 + 2 U2 1.96TB Micron drives. I installed two Orico 5,25" to 2,5" adapters and passed the cables with the same opening that the optical SATA cable uses, replacing the DVD drives. You can't use U.2 drives with the original SATA caddies.

    U.2 drives that I used had the standard 2,5" form factor, same screw places, same size, different connectors. Check if the drive that you want has the same form factor, some drives don't have.

    Thanks so much for the great pointer! This is your 5.25” to 2.5” adapter, I think:

    It would be great if someone made a 3.5” sled with space for the U.2 adapter cable and the U.2/ 2.5” drive so it could slot into one of the 4 bays.

    Don’t you need that SATA cable for power, or does the card supply enough power?

    Yes, exactly.

    I doubt that anyone will make an adapter for the caddy, it's a small niche of an already niche product. If you install in the optical drive bays, you can use the HDD bays for a fast internal backup.

    Next time I'll go there, I'll take photos of the setup. I did a quick throughput test, without heatsink, with my SSD7101-A + M.2 to U.2 adapter and the 9300 1.96TB Micron drive is slower than my 970Pro, but for the size/price it's worth.

    You have to remove the SATA cable, install the U.2 cables, then reinstall the SATA cable, the opening is tight for the U2 connector.

    Btw, it's a very clean install, everything is hidden, you just see the U.2 cables next to the PCIe fan.

    @ZombiePhysicist Take extra caution if you plan to RAID these for increased speeds. 10.14.5 public release MIGHT fix some of the issues, but the Mojave RAID issues with U2 drives were even more pronounced than straight SATA drives for some reason. Had a client who decided to repurpose (much lower capacity) server U2 SSDs for video usage, got everything working, then basically lost everything a week or so later. As singles they appear to be 100% fine. Backup and backup often.

    One thing I liked about SSD7120, no fan, zero noise - but U.2 drives are stupidly hot. Something like the first WD Velociraptor 3,5" to 2,5" adapter, or that Chinese clone without the SATA connector, seems a smart choice to install U.2 drives

    Thank you. If. I get this, I will get just the one 15tb drive, maybe a 2nd as a backup, but no raid. It’s about 3700bux, so I’m going to wait to see if wwdc intros the new Mac Pro.

    If it’s like the cheese grater Mac with pci, I will get that and invest in upgrades there. If it’s another 2013 trash can “modular” disaster, I will eventually dump apple hardware (maybe go to Linux and just run OS X in emulation as I transition). It’s worth it to wait a couple of months before investing in this depending on what apple releases. If they mess up, then this upgrade might get me through a few more years as I learn about transitioning away from the Mac. If they make a great pci based Mac Pro, hooray, happy days.

    Btw, looks like the price is already dropping under $3000:
