Custom Laptop Storage Advice

[wrenaudrey]

I am purchasing a custom laptop very soon. And I have been eyeing the Lafite II from PCSpecialist UK for a long time now.

I have a budget of £550-£650. Needs to be small, portable but with reasonable performance. So this is the spec:

CPU and Memory is pretty much staying as it is.
As title says above, it's the storage that im iffy about.

Storage options are:
Samsung SM951 256GB M.2 nVme
Samsung PM951 512GB M.2 nVme
Samsung 850 EVO 500GB SATA

Pretty much all these 3 drives will land me inbetween my budget.
My thinking with the M.2 drives is that, i could choose to have that in and later down the line if when needing more storage space, i could easily just pop a 2.5" SSD in.

However, i have worries about M.2 specially with nVme because i may be paying for a drive that will not really perform as nVme is advertised because of the CPU(i5 6200U) and maybe(not sure) because of the PCI-e on the actual board not really being compatible and hence the nVme drive just performing as a normal SSD.
Also, i've read when researching the drives that they get really hot and sometimes not performing as advertised(for example, performing even worse than a conventional 2.5" SSD). Also another is that, there is actually no support from Samsung on these M.2 drives as they are OEMs - so if they break, your stoofd.

Anybody had a chance on using/installing these drives?
Should i just not worry and get an M.2 drive?
--But which one, SM951 or PM951?

So any advice you can give me will be really helpful.

Thanks in advanced.

PS. If i had the option to get the Samsung 951 Pro, i wouldnt blink an eye, i'd just get that. But its not the 951 Pro, that's why im asking for advice

I have an 850 EVO in my current laptop and I'm very pleased with it. I haven't had any problems with overheating or anything (and my fan doesn't even work properly all the time!), so I doubt it will be a problem. As for performance, I think the bottleneck is more likely to be the CPU, since it's an i5.
