Which NVMe is better?
Posted by RandomFleshPrison@reddit | buildapc | View on Reddit | 18 comments
I tried to check online, but different sites have different answers. One is a WD Black SN750 NVMe 1TB, and the other is a KINGSTON OM8PGP41024Q-AA. The former seems older but higher quality, the other newer but cheaper. I can use either one, with a fresh OS install.
Advice?

Either
The Kingston is PCIe4 vs PCIe3 so in theory a little faster
Spec sheet says its 640TBW as opposed to 600TBW for the WD
So durability is simiilar, both are probably TLC
Durability will be about the same
So if its cheaper get the Kingston but either will do

WD SN750. It has dram (double check now, but it used to have, maybe newer batches don’t). Its a much better drive overall than Kingston.

Definitely the WD.

SN750 1TB benches around 3470 MB read sequential with real DRAM cache. The Kingston OM8P is a DRAM less OEM drive that caps lower and drops hard past its SLC cache. Frankenstein the SN750 as boot drive and you will feel it every OS install and Steam download.

Don't have much experience with Kingston aside from their flash drives which are decent but I've had a few WD Blue SSDs & they're usually pretty reliable. I use 2 of their blue NMVEs in my PC & haven't had any issues with them afor a few years now.

Passmark says that the Kingston one is about 50 % faster.

Userbenchmark says the opposite, thus my confusion.

User benchmark should absolutely never be trusted. They are a complete joke.

Oof. Apparently, if even AutoMod warns about it.

I can't find it in UserBenchmark.

The WD Black SN750 is a Gen 3 PCIe max around 3500 MBytes/sec, the KINGSTON OM8PGP41024Q-AA is a Gen 4 PCIe max around 4,417 MBytes/Sec.
I suspect the Kingston Gen 4 will offer lower latency even if the speeds are sort of close, and would get the Gen 4.

are these ur only 2 options? I would go SN750 as much as I hate the price of that usually as Kingston's lower end drives are almost always QLC
RandomFleshPrison@reddit (OP)
I already own them both. I am Frankensteining two computers together.
AshleyxAffliction@reddit
Surely you could test them yourself then if Google is giving conflicting information?
RandomFleshPrison@reddit (OP)
Looks like I will have to.
No_Spare1827@reddit
oh then the SN750 for sure
