Crucial P5 plus Momentum Cache feature.

Hi!
I recently made the switch to SSD only system, cant tell ya how nice and at the same time weird it is to not hear those HDD's working, only thing im hearing now is coil whine and a slight buzzing of the AIO pump when doing heavy workloads on the system
I bought a Crucial P5 Plus 1TB Gen4 SSD , in general, i am very satisfied with my purchase. I have ran some benchmarks on it with AS SSD to see what Momentum Cache really does, and it does make a a big difference in some workloads.

in the attachement is a screenshot with bench results. The bench result on the left is with momentum cache disabled, the other one is with momentum cache enabled.

EDIT: added crystaldisk benchmark results (NVMe setting checked, profile: peak performance). First one is with Momentum Cache enabled and the second result is with disabled Momentum Cache.

So does Momentum Cache really increase the write speeds close to 8000MB/s ? ive read this feature is also risky when used in unstable environment, high risk of data loss due to the fact that it uses a fair amount of my ddr4 ram to cache write commands to the Crucial ssd. I'm an moderate overclocker, i like to play with settings and with that, comes bsods (not really anymore, running win 11 now, miss them bright blue screens xD) anyway, my system is bound to crash every now and then, so is the extra 4000MB/s read/write speed really worth it ? only real applications i would see benefit in, is in games. but since most games already load extremely fast i cant tell the difference.

It's just using your spare ram as a giant disk cache.

yeah it seems so, still, after some tweaking of DDR4 ram, i managed to get above 10.000MB/s sequential read & write speeds with benching.
The fastest NVMe SSD right now is the WD Black SN850, read/write 7000Mb/s 5000MB/s. still significant slower than myn.
The Crucial P5 i bought was 95 euro and the cheapest WD black sn850 i can find right now is 150.
only downside is the risk of data loss, but that still has to happen, will see how it goes from there.

It's not worth it. The actual difference isn't noticeable in real world use, so you are just risking your data for no reason other than higher benchmark numbers.

yeah, the jury is still out on the risks though, i mean in the past 48 hours ive had some crashes because of testing and benching. and not a single file has gone corrupted or missing. ive setup windows in a way that i can have it formatted and reinstalled within 20 min. drivers and basic monitoring apps included. so it wouldnt be the worse thing in the world if windows got corrupted, if files go missing however, then its time to rethink my setup. i do agree on these speeds not having a noticeable impact in the real world, other then it being abit "future proof". its also nice to know the p5 costs less and performs MUCH better than the WD black SN850 beast! again, still have to see if risk is a true factor or a "worse case scenario" kind of thing.
