So a few days ago (due to my STRIX
3090 oc being cancelled and getting the refund) i replaced my 12? y old
Sony vaio vgn-aw11m/h laptop with a brand spanning new Acer Nitro 5
model AN517-52-74YB. Going to adult school for classes in 3d modelling
with blended in September so needed a powerful system. The schools basic
systems a few years ago were barely capable of running Lightroom
smoothly, so i don't have much faith in them rubbing blender smoothly
lol.
Anyway, set it up to my
liking, did some benchmarking on the ssd and found the installed SN530
(very little info on it through Google) capped at approx 2400R/1900W.
I
had a spare Samsung 960 pro 512GB (which I originally was using as an
nvme USB drive through an enclosure) and cloned the drive over with
Acronis. Opened the thing up this evening swapped the drives out,
changed the bios settings from that crappy (optane with raid) over to
AHCI, installed the Samsung nvme driver and ran CrystalDisk mark again
(v8.0.2).
My read speeds increased
to around the expected 3000MB/s, but the write speeds didn't move 1
bit. Capped out at the same 1900. Samsung Magician reports the drive as
running in PCIe 3.0 x4 mode as it should.
Now
since I'm a desktop system builder mainly, and this is my first new
laptop in over a decade, i have 0 experience if this is normal behavior.
My Sony laptop ran it's Samsung 860 in SATA II mode, so i have nothing
to compare with, other than the fact that knowing the 960 easily
achieved over 3000on both read and write in my desktop (before it got
replaced by a 970 Evo plus 1TB).
So
i guess the question is, is this normal behavior? Despite operating in
x4 mode that the write speeds are only approx 2/3 of what they should
be? Are laptop nvme speeds normally slower than desktop speeds? Please
enlighten this primally desktop user.
