Sintech M.2 NGFF NVMe SSD Card for Upgrade Mac Mini Late 2014 Year A1347 MEG Series

I have mac mini late 2014 8GB ram 1TB HDD, it was running very slow.first I thought Processor is not fast enough, So I changed Heat sync tube, for cooling down processor.then I bought Cooling pad for mac mini. Nothing worked.After I see some videos to replace HDD with SSD.I could have purchased 2.5 inch SSD but that gives max 450 MB/s So Better to go buy NVME hard Disk.Right now this Mac mini processor gives max read and write speed around 750 MB/s.You can't increases your RAM, so better to buy NVME instead of 2.5 inch SSD. SO it will give you max speed.now my mac mini working like charm.No Lag , No progress showing. opening chrome and other apps very fast.
