Post your CrystalDiskMark speeds

AMD 3D V-Cache enables RAM disk to hit 182 GB/s speeds — over 12X faster than the fastest PCIe 5.0 SSDs

Who needs Intel's Optane when you have AMD's 3D V-Cache?

Hi,
Knocked off 27c off the max temp adding a cheapo heatsink to the sn850x 4tb

Hi,
Got another sn850x 4tb for my z490 rig doing pretty okay with the new cheap thermalright m.2 cooler I got
970 evo plus 500gb temps went down 4-5c to
Added my filter back on so minimums went up a little :/

almost 10 years 840 evo lives on

Still dunno why the sequential write is so low, but it's no matter.

Peaked at 52C controller temp under motherboard heatsink. Seq write seems a bit inconsistent.

Nothing special for an entry-level PCIe 4.0 drive but it does its job. I have another as well

I had a typo, it's NV2

NV2 is a fun lottery. One of my friends got an incredible version of it and a surprisingly slow version of it. On the same purchase.

I think they just have a bunch of controllers/NANDs they stick on it. AFAIK you can even get TLC or QLC.

Hi,
Issue would matter to myself
Any issue contacting samsung about it ?
You buy second hand/ used or something ?

It's a windows issue, running KDiskMark doesn't show the same thing. It's just pretty inconsistent. It was bought new.

Hi,
Write issues are usually when disks get full yours is obviously not full so :/

I have an another one. Speeds are reasonable at PCIe 3.0 x2

It's particularly inconsistent. Seen it since I bought the drive really, but I've never had any issues.

If you do copy a file (from the drive to the drive) the speed is consistent. I dunno what makes CrystalDiskMark weird there, but I chose to ignore it as it has no issues, and running the benchmark under linux using KDiskMark always gives me 3GB/s

Samsung evo 970 + primocache (30GB read, 10 GB write caches, with deferred-write enabled):

Please note that deferred-write is dangerous if system is shut down without flushing the cache. You could miss some data like windows update binaries, game saves, etc, they can be corrupt. Possible other causes are unstable RAM and unstable power grid.

Please also note that deferring writes decreases SSD usage a lot. At least when you have big RAM (I have 64GB, 40 GB for caching). Then SSD life is improved.

If prices were same, buying a bigger RAM + caching would be not worse than buying a faster SSD while being better for some apps that require a lot of RAM too. The problem is, Windows 11 does not do this caching by itself. It just enables a lot of unnecessary features by default such as memory compression (not needed with 64 GB RAM!).

Without deferred-write:

slow but safe. At least works fast in open-world games. I don't even see a loading screen.

Corsair MP600 Pro LPX 4TB on the SB

Edit that one run cost about 252Gigs of reads and 269Gigs of writes..............I wonder if it thermally throttled during the test.

Not sure why I could not edit.................
Result was from FW EIFM31.4
Newest FW is EIFM31.6 and corsairs FW info and changelog is abysmal.

Hi,
Yeah tpu edit timer runs out.

970 evo + primocache + 5200 MHz DDR5 with tightened timings

1x Optane p1600x 118GB

Optane 900p 480GB

Interesting so it's not just modern cpus inflating the random read numbers on my P1600X, it actually is faster at random reads than the 900/5p. Im getting 420MB/s QD1 reads but I have 13th gen. Do you know if AMD is hindering your scores or not? That's the only other explanation I can think of besides it actually being faster which is weird seeing how much more expensive those drives are than the 1600x.

i am a rare breed here because im running a sata ssd, for some weird reason, write speeds were pretty low (atleast for this test)

@P4-630
hope you have a good UPS.

for me, including results using a ram disc, arent really "drive" benches..

Hi,
Up until a few months ago I to was primarily using sata ssd's so nothing rare about it
I still have win-10 and 7 on sata hehe

Swapped out the 500gb 970 evo + for the 2tb 980 pro on my z490 rig, 2tb os drive
I'll put it in my x299 rig when I get it back running again
Cooler than the 970 evo + for sure

It was from a Toms article I linked

OS drive 500GB (CT500P5)

game drive 1TB (MSI M470)

didnt include the other 6 drives, as all are at least 10% slower.



@P4-630
my mistake (was to quick scrolling over posts), thought those were your numbers.

i said that because of this page when scrolling saw speeds around few to several GB/s. Anyway, on my main pc i have bx500 120gb for os and another 480gb one for few games and it's fine for a modest build like mine.
