Hi all got a couple of questions.

I have a msi b350 tomahawk that has a m.2 slot, i have looked on msi website and only found the following:

Storage

• AMD® B350 Chipset
• 4 x SATA 6Gb/s ports*
- Support RAID 0, RAID 1 and RAID 10
• 1 x M.2 port (Key M)
- Supports PCIe 3.0 x4 (RYZEN Series Processors) or PCIe 3.0 x2 (7th Gen A-series/ Athlon™ processors ) and SATA 6Gb/s
- Supports 2242/ 2260 /2280/ 22110 storage devices

What am after finding is as it only has 4 sata ports and i have been reading that if i was to put something in the m.2 slot its possible i would lose some sata ports ? So just after some conformation.
The other is, i have now a samsung evo 850 250gb ssd , now i have seen this m.2 one samsung 960 evo its under the compatibility list for my motherboard and its says :

M.2 Internal Solid State Drive
Up-To 3,200MB/s Seq. Read
Up-To 1,500MB/s Seq. Write
PCIe 3.0 x4 NVM Express
3 years limited Warranty

Now if i can have this, and keep my sata ports am i going to see a difference in loading times (gaming 95% of the time) to my other ssd's.

Thanks in advance :)

I just had a look in the manual from the MSI website, you dont loose the use of any SATA ports or anything on that board, the M.2 Drives gets its PCI-e lanes from the CPU, along with the Graphics card, thats the 20 PCI-e lanes used up that the CPU can supply, 16 for the GFX card and 4 for the M.2 drive.

On boards with 2 M.2 drive slots, usually the 2nd M.2 slots shares its lanes with the very bottom PCI-e x16 slot, so you loose use of that slot, but those get there PCI-e lanes from the chipset.

Having an M.2 nvme drive vs Ssd is like going from a mechanical hard drive to an ssd, much faster, I went from 3 x Samsung evo 840s in raid0 to a 960 evo nvme, the difference is lightening.

As for loosing sata ports, check the manual for this, I don't think you loose the use of anything, 16 pcie lanes for the graphics card and 4 for the M.2 slot.
