NVMe vs AHCI, for m.2 drives

5 posts in this topic

I'm currently using a Samsung SM951 AHCI 256GB M.2 as the boot drive (write 2200)

Thinking of replacing it with a WD Black NVMe 512GB M.2 drive (write 2000)

Will the WD's being NVMe (write 2000) compansate for the performance difference, over the SM951 being AHCI (and 2200 write)?

What are you doing that you're hoping to see a performance gain in? I can't get behind what WD is doing with SSD right now, there are many other better options.

I like to store my mp3's and music video on an SSD, for faster access.

And stuff might get a little crowded on my current 256GB M.2 boot drive.

So instead of buying a separate 250GB 2.5" SSD for my music stuff, thought I might as well go and replace my 256GB M.2, for a 500GB M.2.

I doubt you'd see any perceptible performance difference, but if you need the capacity, then go for it.

Agreed, though I'd probably just add a second drive rather than migrating OS and such to a new one.
