How to get 7000 mb/s speed on ssd m2?

Question

Solid State Drives

Good afternoon I am currently building a new computer from>
MSI MAG B550 TOMAHAWK Gaming
AMD Ryzen 7 5800X
ASUS ROG Strix Radeon RX570 8GB Gaming
 WD Black SN850 NVMe M.2 2280 1TB
And the question is:
Where to insert SSD (SN850) to get maximum speed?
Since the top PCI-E 4 slot on the motherboard with a video card and there is also a slot for an SSD next to it, but if I insert it there, will either the video card work and get 7000 mb / s speed?
Bottom slot on motherboard with PCI-E 3. (total 2 slots PCI-E 4 and PCI-E 3 on MSI MAG B550).


I really hope for your advice, as this is the first time I work with a 4th generation SSD!

PS there is also in my build:
MSI MPG Series 850 Watt 80 Plus Gold
Corsair Vengeance RGB Pro SL 32GB (2x16GB) DDR4 3600
and
HDD 3.5 -1 : WD 3TB Red (Sata 1)
HDD 3.5 -2 : WD 3TB Green (Sata 2)
I think the rest is not important :)

Answer 1

The bottom slot is connected to the chipset, so it is locked to use PCIe 3.0 lanes.
Actually, you don’t have so many options - start by installing it in the top slot and see what happens. The computer is new, you should not have any collapses with the loss of information.
It is difficult to talk about seven thousand, but I think that in the region of 5000 MB / s you will probably get it. Do not forget that the high write speed will be about a quarter of the volume, then even the dynamic SLC cache will end.
Although, if you are going to play without working with some large projects, then it is not entirely clear why such speed is needed - it will be rather a pleasant bonus.
If you doubt the mode of operation of the disk, then the type of connection and the interface used can be viewed, for example, in R. tester . You can also run tests in it.
PS
If my assumption about the appointment of a new computer is wrong and you are going to use the disk intensively, then in my opinion, it will be much more important to take care of cooling.
It is clearly not worth actively driving such an SSD without cooling - from overheating, it can go to another world much earlier than you expect.
