    I made a video showing how to build your own fast external NVMe SSD:



    I am using this setup with a Macbook Pro and will continue to use it as a boot drive with the new Mac Mini. I am thinking that it is the best way to get a fast and large SSD without becoming poor at the same time.
    • Sonnet Echo Express SEL TB3 enclosure: 200$
    • Samsung EVO 970 2TB: 545$ (227$ for 1TB)
    • PCIe adapter card: 21$
    Not long ago NVMEe USB enclosures become available. Has anybody tried one of them yet? I don't think that they will be as reliable as a Thunderbolt solution (no TRIM support?). But I am interested in knowing more...so please tell us about your experiences!

    I actually just ordered this one and sent it back. It worked good, but I didn't want to spend the money for it yet. I used it to copy my data off my m.2 nvme drive (samsung 970 evo 1tb) to an external SSD so I could transfer to my new MBP when it comes in. The PC that was in died so I had to get something to get my data off it. It worked great and was very fast.

    You need a TB3 enclosure over a TB2. Do they not have one somewhere? For what I needed the above worked, and I'm sure it is fast enough for most people for the price. Easily 1000+ R&W

    I actually got my Mac mini 2018 i7 and the performance of all SSD drives is better.

    does an NVME M.2 SSD via a thunderbolt 3 enclosure like the one above or the TekQ Rapide support TRIM? i have a new 2018 Mac Mini with 256gb storage. currently, for extra storage, i'm using a Samsung 860 EVO SSD in a USB-C, USB 3.1 gen 2 enclosure. But the read/write speed tops out at ~400 MB/s and i can definitely notice this difference in speed when i'm accessing a large Lightroom catalog that is stored on my external SSD.

    im going to be building something similar. I think im going to get the OWC Express 4m2 for the enclosure... I also get a decent deal on the EVO970's through work with login ($449) for the 2TB 970 evos. I can start out with one drive (wont be as fast) but then add the others as time goes on or when I need it.

    The drive appears for macOS like an internal NVMe drive with the same features as the internal one.

    USB 3.1G2 will definitely do more than that. I'd check in System Information (about this mac > system report) and check the USB device tree - check that your device is running at 10Gbit/sec.

    Oh. I just looked up the 860. That's your bottleneck right there. Samsung only claim it'll do a little over 500MB/sec. A different SATA SSD won't help, as they're all limited to SATA6G speeds.

    If you have the M2 version (and thus an M2 case) a different SSD would help.

    A USB3.1G2 case using an NVMe M2 gives me roughly double what you're getting now. (700/900 write/read).

    the enclosure is hot, you can touch it while using it, but its very hot.
    so i recon head dissipation is efficient.
    drive idles around 50 degrees celsius, and goes up to 70 when under load, supposedly normal.

    Has anyone had any experience (good or bad) with Vantec USB3.1G2 NVMe cases? This has popped up as available via a local retailer quite cheaply, and I'm wondering if its worth trying (I currently have an NVMe sitting in an unreliable Orico case that I haven't sent back yet.

    Did I say it was? I literally said it's a USB3.1 Gen 2 case.

    It is ok, but the title of this thread says specifically Thunderbolt : "DIY Thunderbolt 3 SSD"
