Hi guys,

I just have upgraded my iMac 27" mid 2015 with a 1TB NVMe Samsung EVO Plus and I am getting low speed results for this kind of SSD.. before I was getting almost the same speeds as an external USB SSD drive.

Anyone knows why I am getting these low speed values ?? These are abnormal speeds for these kind of Samsung SSD.

hi, because you bus speed, if you have a ssd with 1000 MB/SEC write but your computer support only 500 MB/SEC write, in your Mac you have low write and read because the buss speed iMac model.

Hi do you think I can swap my iMac mid 2015 logic board with a compatible PCI X4 logic board from another iMac model? I was thinking the late 2015 logic board.. do you think this logic board is compatible with the mid 2015 with the iMac case and conectors?

Samsung nvme 960, read: 2542 / write: 1431 MB/s
Does the speed stay the same for you with multiple attempts? The first one looks the same but write drops to 371MB/s and read to 1031MB/s for me :(
