The systems I get in with these adapters tend to have bad SSD's as the CRC error's finely catch up killing the SSD, SSD's that die in a couple of years is not good economics! Putting one into a iMac is risky in my option as its already so hard to get to.

Maybe they are getting better I haven't tried one in the last year. Many people are just not skilled enough which is why OWC (and Transcend) decided not to get into supporting exchanging out the blade SSD as it was just so much harder.Īs for using these M.2 adapters I'm not a fan.

If you still insist on using the non standard EVO then Samsung released an firmware update for the EVO Plus that fixes issues on Mac, you need to upgrade it first using a PC before putting the drive in your - Theres a couple of issues here that you glossed over.įirst the newer 'Thin Series' iMac's are harder to open up without damaging the display and taking the logic board out adds to it (and a bit of a shock risk). I recommend the regular EVO not the EVO Plus or EVO Pro. I am happy I did it and got rid of the FusionDrive setup.Īs a note, if you plan to replace the SATA drive with an SSD, which I also did then 'No' you do not need the overpriced and useless thermal Sensor from OWC either. I have some images on instagram where I did my upgrade.: I only recommend the Sintech adapters, others are known to have issues. I did my 2017 iMac with a EVO 970 NVMe SSD + Sintech M.2 NVMe to Apple PCEe adapter. Even from OWC, which only wants to sell a SATA upgrade kit for the 2017 iMac.

I am amazed how much confusion information is on the internet about this topic. Upgrading an 2017 iMac 27' with an off the shelf NMVe m.2 SSD + M.2 Apple PCIe adapter is definitely possible.
