I also did not test different adapter brands, yet.ġ. I am just tired of tearing down the iMac again Recommended: sintech adapters seem to work most of the time.Īlright, I did not unplug my NVMe again.
sometimes it is just the M.2 Adapter which is not working with your Mac and/or NVMe SSD model. even if the NVMe is connected correctly, unplug the NVMe SSD from the logic board and replug it again sometimes change the 2 lanes to 4 lanes. the NVMe SSD isn't connected to the Adapter correctly. Some people posted that sometimes the slow benchmark results of around 750 and 2 lanes instead of 4 come up because: I did some research and it seems like there's no way of getting the iMac to use 4 lanes, right? I checked the lanes, 2 lanes instead of the transcend's offered 4lanes.
When I saw the transcend ssd Benchmarks I was pretty much ****ed up because I was expecting much higher R/W scores. seriously guys, benchmarks where not even close to 100 for reading/writing xD xD xD Is an iMac SATA HD really that slow normally? I also checked the SATA 1TB built in benchmarks and. I ran several benchmark tools and all of them came up with 700 to 750 for both, reading and writing. I bought a cheap NVMe PCIe M.2 NGFF SSD 2013 2014 Adapter on eBay for connecting the transcend to the PCIe slot on the logicboard. Yesterday I added a NVMe 1.3 PCIe SSD transcend 220s (DRAM cache version) to the built in 1TB SATA HD. I recently upgraded the ram from 2x4GB to 2x8GB, iMac is working perfectly since then (maybe for 4 weeks + almost 24/7 turned on). I got me a late 2013 iMac 21.5 a couple of months ago pre owned from eBay.
