Works great! Exactly what I needed for wd_black sn770

Has served me well with my MacBook Pro, easy upgrade to storage without hunting down OEM drives. I have heard mixed things about using boards like this but let's face it, you are using it on an old Mac, if you really need top of the line reliability, you probably shouldn't be using an old Mac.Better to keep one useful than let it go to waste, this is pretty awesome for that! Have used semi-regularly for a few years now, worth the price of admission!

I was afraid to touch these after reading about Kernel Panics with Non-Apple Upgrades in the past. But able to get a nicely discounted WD Black SN750 1T SSD and figured it was worth a try for so little financial risk. Last year I replaced the internal battery and that helped it, but the Apple 256 GB SSD only tested in the mid low 100s on BackMagicDesign and reading email could be a pain. I was using External Drives for DropBox and Photos because I had no room. So everything could suddenly become slow.Before I replaced the drive I downloaded the latest macOS Monterey 12.4 installer from the Mac Store and then used Terminal commands from an Apple support article to create a Boot USB Installer drive from a 32GB stick I had lying around. I confirmed I could boot from it and then opened the MacBook. At first I had an issue with my MacBook not recognizing the new SSD Card, but when I went to put the original back I realized I didn't have it pushed into the SSD slot far enough. After that I was fine.After booting from the USB and a fresh install of Monterey I then restored the rest of the data from my Time Machine backup that I made sure was current before this. And the OS install and restore went so much faster than any I had done before. In a couple hours I was back up and running and just had to fix some setting. Now my MacBook is portable again without all the extra drives I needed before and the drive is so much faster.After a week everything is great. Not issue at all. I used it off the power cable and external drives for the fist time for several hours this weekend. Will help as I wait for a new M2 Pro/Max PowerBook Pro to come out.My only regret is that I didn't pick up the 2T WD Black sn750.

UPDATE: After a week of this being installed, my iMac began to kernel panic to then reboot to a missing volume (folder with blinking question mark). The cause was this adapter according to Console. Then I began reading that this isn't a reliable adapter as they can begin shorting over time due to heat, causing kernel panicking and potential data corruption. Luckily I can be in and out of my iMac within 20-minutes since I've yet to reseal the display. But to the novice, a failure of this magnitude may become time consuming if not costly by way of hiring a tech to redo the install again. Therefore, I do not recommend.*********************I hadn't worked on an Apple product for sometime outside of software. So when I purchased a used 2019 21.5" iMac that came equipped with a 256GB SSD, I knew I needed to upgrade the drive as well as the RAM (came with 8GB, but neither here nor there). However, there wasn't a lot of PCIe SSD options available that were affordable. So I looked into picking up a Crucial P5 Plus NVMe 1TB drive instead, but needed to adapt it to PCIe. Therefore I took a chance on this adapter, though I hadn't seen anything about it being compatible for this particular machine. Good news: It's totally compatible.Low and behold, the adapter works great. I'm typing this review on the very machine I upgraded. I was able to format the Crucial drive to Apple's APFS format under a GUID partition map through this adapter without much issue. Drive speed tests were quick and I've yet to experience any stability issues. So far, so so so good.The only "issue" that someone needs to keep in mind regarding Apple's PCIe socket on the main logic board (MLB): It's a stiff, highly resistant fit. So install the adapter first to the MLB if you can while doing your best to support the PCIe socket itself to not hurt the MLB beneath. After that is when you can then put the NVMe drive in place. Do not try to install the adapter onto the NVMe first then installing to the MLB. You run a high risk of damaging the MLB, the new NVMe drive, or even the adapter. Sometimes you'll feel like the adapter is seated perfectly in there, like it cannot go in any further. But then you'll discover that the NVMe drive's screw hole won't match up with the logic board. The adapter will need to be pushed in further until there's a very noticeable 'click' into place. But that has nothing to do with the design of this adapter. Rather it has everything to do with the parts Apple used to assemble their main logic board itself. I'm not knocking any brand here, so you know. But it is advice should you encounter this same stiff socket on your own machine.

I bought this for upgrading a Late 2012 iMac without realizing that model still used the older mSATA interface with a different pin layout. I ended up returning it but not before testing it on a 2014 13" MBPr out of curiosity. Snugged right up to the Nvme 2280 blade I paired it with, and the combined length was a perfect fit on the board with the screw at the end lining up nicely. Had previously cloned the drive off the blade it was temporarily replacing so system detected the new drive at startup and booted normally. I ran speedtest a couple times and noticed similar if not slightly higher numbers than the OEM blade it replaced, which isn't surprising given the bottleneck here is the older interface and not the drive itself. I then let GeekBench 6 run on a loop for an hour just to stress test it and didn't see any hanging or kernel panics either, both of which were an issue with older adapters of this design.TL;DR this is a suitable replacement for anyone running older per-butterfly keyboard or M series Macbooks and certain models of 2013 and later iMacs that support an SSD blade. Those OEM parts are harder and harder to find, and those available typically show signs of aging those early gen SSD's are known for. With this adapter, you can take the latest Nvme Gen 2 drive that run ~50-60 bucks/TB and give your older Macs a quick boost in capacity and possibly even performance depending on the condition of the drive you're swapping it for.
