Hi all - I need more space in my system, currently have 3 x 2.5" SSDs. I'm confused about M.2 SSD's as I've heard they don't run at full speed (or at all) depending on mobo support, will the following work properly in my system?

 

Samsung 970 Pro M.2 SSD

 

Motherbaord: Asus Z97-A USB3.1

 

Thanks for any info.

Yes that would work in that motherboard. But its only rated for standard ssd speed and not nvme speeds.

I think, guessing a bit, that your confusion comes from the fact that M2 comes as NVMe and SATA types.  NVMe runs directly against the PCI lanes so runs at the "full speed" I believe you are referring to.  These can go at up to 3500MB/sec! The other M.2 SSD types use the SATA inteface and run like SATA drives do (so typically up to 500MB/sec ish).

 

If your motherboard supports the NVMe type definitely go for it. Its blinding how fast things become!

 

I'm not sure if your motherboard supports NVMe. Tried some googling and got confused. People were talking about "with an adapter". Not sure if they mean a PCIe card or not.

From the spec page I listed my motherboard supports only M.2 in PCIe (NVMe) and not SATA mode. It says bandwidth is shared with x1_1/2 slots (not in use). I since confirmed out all Asus Z97 boards support NVMe:

However as JaseNZ mentioned there is a question on the speed its rated for... I'm still not sure exactly what this is, but if its faster than 2.5" SSD I might as well get it, pretty much the same price as an 860Pro.

I've got a Z97 motherboard (not the same as yours however), my NVME M2 SSD works fine and ~ 5x faster than SATA

It has a throughput of 10gb/s which is at least twice as fast as an ssd so by all means drop the nvme in 😀

Sata SSD get about 550 MB/s read speed max

 

NVME drives can peak at around 3400+

I have three M2 SSDs on my desktop - two using a SATA interface and one using a PCIe card. The PCIe is used for boot (if your motherboard supports it) and I just tested this speed today because I am thinking of running some virtual machines. The PCIe M2 reached 1332 MB/s, the SATA ones were doing ⅓ of that.
