Want to upgrade blade SSD with larger drive and break the Fusion Drive
I just need your help for the same matter.
I have a Mid 2017 21.5” iMac 4k retina system, with a 3.4 GHz i5 - A1418/EMC 3069
It’s equipped with a Fusion Drive made by a standard HDD + blade SSD (custom Samsung 32GB, MZ-KNZ0320/A02, SSPHOTON 655-1991A, 89x33mm 3.5"x1.3", PCIe v2.0 x4),
I followed your great guide to almost complete disassembly the iMac to substitute the RAM and the 2.5” HDD with a 2.5” SSD drive
Now I would like to upgrade the blade SSD, as well as break the Fusion Drive of course, leaving it as a separate drive and to increase its size to at least 240GB in order to install exclusively the system, while I use the "main" SSD (that one just put in) only for the apps and data.
It seems that Aura Pro X SSD should be the right solution but I do not find my iMac model in the list of compatibility.
Please help me understnad which model/type/characteristic of blade SSD I need to find, since the matter is very confused.

I followed your indication, finding a 500GB SSD. No need to split the fusion drive since I substitute le standard HD with the great CRUCIAL MX 500 1TB. With also 32GB memory added I can say that “it is another planet”. I can also confirm that after one month the temperature inside is stable. After three-four days almost always one, the temperature il 54°C and fun 1200rpm, so there is no need to buy the temperature sensor.
