Works great! Exactly what I needed for wd_black sn770

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.

took a chance on this unit since the last time i had used the more than twice as expensive sintech. combine this with a 1tb WD sn750 black SSD gen3x4. the speeds for writing jumped from 1800mbps to 2500mbps and write speeds from 1400mbps to 2100mbps. since its a 2015 i did not have to worry about the hibernation issues and so far it works like a champ. i'll try it again later on a 2014 model and see where that takes me. the 2015 mbp have the pcie with gen 3 with 4 lanes while the 2013-2014 have gen3 with 2 lanes so the 2015 is litarally 2 times faster in read write speeds than the 2013-2014. just go by your own numbers of performance boost. i used blackmagic disk speed test from the app store for the performance numbers. remember to create your own usb bootable disk when installing a new virgin NVME ssd to speed up the installation process.

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.
