The quality of SSD - feedback from the users would tell some stories about third party SSDs - do some research and you will find a few users' experience. I am perfectly happy with my DIY SATA-3 SSD on my 2015 5K, two 2013 (27') and even SATA-2 on my 2009 Mac Mini Server (yes, I have Fusion drive with two identical Apple 256GB SSD - made by Toshiba). The speed you might gain with PCI-e + SATA SSD Fusion drive might not be that significant (given CPU and 4GB memory). Your Mac Mini is the 1.4 GHz entry level - personally, I would invest all the money to get a Bigger SATA-3 SSD alone for this Mac Mini. I can see you have spent some energy and money to get the hardwares for this task, however: I know some people would want the newest PCI-e SSD with modification of second SSD by replacing the HDD (2014 Mac Mini Fusion version). The fusion drive is combining the 'speed' of SSD with 'capacity' of HDD. Hope you can help, in any case thanks in advance for your attention. Is there anything I am doing wrong? Is there anything I can do to check if the problem is the connector on motherboard? Should the PCIe port need to somewhat activated? In sum, I tried two different drives with two different connectors but in all cases once I power on my Mac the additional PCIe blade drive isn’t recognised at all as it neither was present nor connected. I bought on eBay a connector 821-00010-A and an original Apple/Samsung MZ-JPV1280/0A3 PCIe blade drive coming from a Macbook Pro then a bought a brand new Transcend Jetdrive 820 especially designed for Mac mini 2014 and finally I bought another 821-00010-A connector from a different seller.

It will gather no personally identifiable info. It is very highly regarded and meant to be used with Apple Support Communities to help others help you troubleshoot and resolve your Mac problems. EtreCheck is a diagnostic app that gathers important info about your hardware and software and reports it back to you. I recommend that you run an EtreCheck evaluation of your Mac. Instead, it is something other, such as software conflict or hardware compromise. If so, you should know that very often it isn't RAM that is the problem. Why do you wish to upgrade the RAM in your mini?Īre you having some performance issues with the computer?
