Hello guys, I recently upgraded my mobo and storage on my gaming and music production pc. I have a gigabyte z97x-sli rev. 1.2 mobo and a Samsung nvme m.2 256 gb ssd. I installed windows to the ssd and it boots up fine but when i benchmark the ssd it only reads about 400 mbps. Is there something else I need to do in order to get more performance gains?
 
not really a dummy mate its pretty confusing for a lot of people with m2 drives

some m2 drives only do sata speed some do pci-e speed

but then to get the max out of them your motherboard needs to support pci-e x4 m2 drives

yours doesnt

though would have expected it to be a bit faster than what you are getting but dont know how the pci-e lanes are shared on your board

This transition period we are in is quite confusing.
SATA III, m.2, mSATA, m.2 PCI-e, NVMe...not all boards can use all, not all bards can boot even if there is a m.2 port, an m.2 port can disable 1 or 2 SATA ports, etc, etc.

HDD to SSD was/is a no brainer.
These other options and other formats...you really have to investigate what your system can actually use.
