Question SSD Compatibility

[StellaMan]

Hi, I have been asked to upgrade an M.2 SSD to a bigger size and possibly a 1 Tb HDD to a SSD. My knowledge of the newer M.2 type drives is severely limited, so I'd like some advice please ...

The M.2 Drive in the laptop (which I do NOT have in my possession, so this is the only information I can provide) is a Kingston PCI Express 128Gb U-SNS8154P3/128GJ ... I can see that this is an Interface Type NVMe 1.2 / PCIe Gen. 3 ... am I restricted as to the replacement Drive I can put in or does it just have to ne NVMe and M.2 ?!?

I am also concerned that if I buy something like a WD_BLACK SN850 NVMe SSD, which can download at 7000MB/s will that speed be allowed by the Motherboard or would I be wasting money ?

Thanks for any help & advice here

What specific laptop is this?
That may limit what drives can go in it.

And if the M.2 port is Gen 3 (likely), that will NOT allow full speed of something like the Gen 4 SN850.

I don't know the laptop model, I am waiting for the owner to get back to me.

Any PCIE 3.0 M.2 drive should work just fine.
Samsung 970 evo - for example.

Do not be overly concerned about ssd speeds.
Those sequential benchmarks pf pcie droves do look wonderful, but you will be hard pressed to tell the difference among all ssd devices. Most windows i/o is random and that performance varies little. It is, however some 40x faster than a HDD.
Here is an illustrative amusing video:

Do you need to preserve any data?
If you have an open m.2 slot, the process will be simple.
A 128gb C drive is very small and should be increased.
Many things default to the C drive.
How do you propose to manage these updates if you need to preserve data?

Thanks for all your replies, input and advice, in the end none of it mattered because my client decided he'd keep the laptop for work only and buy himself a Gaming machine
