I might have gotten a great idea, but im not sure if it will work out. The idea is to get a SAMSUNG 960 EVO M.2 250GB SSD and a Aqua Computer kryo PCIe 3.0 x4 adapter for M.2 NGFF PCIe SSD. But here comes the questions. 1. This pci adaptor is a stated for PCI express 3 X4 , but i only have PCI express 2. Does any one know if it can work in PCI express 2 (i am off cause aware that if it work, it will run at reduced speed cause of lower speed on PCI 2 contra PCI 3, but PCI 2 at X4 still has a speed of up to 2000 MB/s transfer rate and that is still far better than the onboard sata 2 or sata 3 with the crappy marvel controller that not can give true sata 3 speed. onboard sata 3 maxes out at 400 Mb/s read and 250 MB/s ride, so here will 2000 MB/s be far better). PCI adaptor: https://shop.aquacomputer.de/product_info.php?products_id=3400 2. Is M.2 so fast that it can give a performence over normal sata SSD but at reduced speed cause of crappy sata 3 controller. Se screenshot under here. The screenshot test is with my Crucial MX300 275 GB SSD. 3. spending this amount of money on M.2 is that even a good idea contra performance gain. The M.2 SSD is ment to be used as OS drive and for the most used games i have?
