M.2 PCIe 2x2 running at 6gbps SATA3?

Plextor m6e 128GB M.2 PCIe 2x2....

so i bought this stick thinking I was going to be moving at PCIe 2x2 speeds of 10Gb/s... but HWinfo reports i'm doing SATA3 speeds of 6Gb/s?

I'm aware of conflicts with m.2 and PCIe cards when using 28-lane cpus like mine, but I only have one x16 card installed in the first slot (GTX 970), my m.2 has plenty of headroom no? The Plextor POST message (very annoying btw) recognises the m.2 ssd as "PCIe 2 x 2", but hardware monitors in Windows tell me SATA3 6Gb/s, what gives?

are you getting the rated speeds?
Just because it uses a two lane pcie (v2) connection means that it will run and faster. A two lane ver2 pcie bus would give a max of 1GB/s by the way, not 10.

i thought the throughput was 10Gbits/s...represented by the small 'b'...

either way, i ran a storage benchmark and you were right, i am getting 700MBytes/s reads... definitely > SATA3! Thank you, not sure why the software is reading 6Gb/s
