Samsung SSD 850 Evo Slow Speeds. Not detected by Samsung Magician. The SSD works as my Boot Drive.

The SSD is not detected in BIOS SATA settings on ACHI mode, but it can be configured to work as my boot drive on Hardware Configuration options. Therefore, the SSD is working and my computer successfully boots with the SSD. The SSD is detected in Device Manager and can be detected by AS SSD Benchmark but not by Samsung Magician or BIOS SATA settings.

My motherboard is the Asus P6X58D-E. It has one SATA 6gb/s port and two SATA 3gb/s ports. I connected the SSD to the 6gb/s port. This has shown improved seeds but not to the level of other people's benchmarks on this website: http://ssd.userbenchmark.com/Compare/Samsung-850-Pro-256GB-vs-Samsung-850-Evo-500GB/2385vs3477. My benchmark is only 384Mb/s Read and 234 MB/s Write which is slow compared to the benchmarks I have seen online. The motherboard is setup in ACHI mode and not IDE or RAID as this has shown faster speeds. I cannot install Intel Rapid Technology Drivers as whenever I try to, my system is not supported, I am guessing this means by Motherboard is too old for it to work properly. My Marvell controller (I don't know what this is) is updated and I downloaded drivers for this yesterday, but it shows no improvement in my SSD benchmark.

I have fully optimized the SSD following articles online and whatnot. Furthermore, the SSD appears as a removable drive and has an eject notification in my taskbar. I know this isn't a major problem, but I would like to find a way to fix this also. Registry edits on Windows 10 for this particular issue do not work.

to get the full speed you need the intel rapid storage driver. to install the driver i needs to be on a compatible sata port. it sounds to me like you do not have a good enough board to get full speed with your ssd on your current setup... to be fair the speeds your getting are not bad, i wouldn't even worry about it.
