Slow read/write on Brand new gen 3 NVMe SSD?

[Thebadgamer98]

I purchased this 4tb Crucial P3 NVMe less than 2 weeks ago from Best Buy.
Could this be a bad drive or a cpu bottleneck? I don't know much about ssd's but I've seen those mentioned before on similar threads.

Here's my relevant pc specs:
OS - Windows 11 Home
Mobo - MSI B450M Gaming Plus
CPU - Ryzen 9 3900x
GPU - Radeon RX 6800 xt

Three options :
1) When you test with 64GiB file, it overwhelms any caching/buffer sizes of said drive might have, meaning - you measure how fast actual NAND cells can get data wrote to them (no "boosters"). Manufacturers never tell you this, you must check reviews to know fast drive is under those circumstances (big test files with longer time period).
2) If writing test is done after reading one, chances are the heatsink is heat soaked and can't radiate heat fast enough (causing drive throttle).
3) Because of inefficiency in garbage collection/TRIM when a lot of data get's wrote to drive (and retained), a Secure Erase of the drive might be required to get top performance from controller.

Secure Erase? So completely wiping the data on the drive?

It does look like your performance is off, but I mean... They're just not great drives. There's a reason they're so cheap for the capacity.

Does it feel slow in day to day usage, or are you just stressing because the benchmark "should" be higher?

It may be the drive - the more you put on it the slower it's likely to get - and it may be your board. Without another machine to test that drive in and another drive to test with your motherboard, no way to be sure.

Good point, start feels a little slow (20secs compared to 10sec) but usage feels fine.

Correct. Put important data on other drive before doing it of course.
BUT, first check if 1GiB test also has those low-ish write limits.

Run the defrag/optimisation (TRIM) tool, and try afterwards.

Why do you put everything on max in CrystalDiskMark? Never seen anyone use settings like that anywhere.... 9 Times a file of 64GB??? And then complain it's slow....

Please start with a normal one like 1 or 2 times 1GB, then show that picture again.
Under settings in Diskmark there is an button Default, please use that, thanks.

It's the same as if you tow a caravan with your car which weighs 1000 kg, you have increased the weight to 64000 kg, and then you go to the garage to complain that your car is slow and can no longer tow...

Of course your SSD is slow to write, its SLC cache is full and you keep writing 64GB files 9 times in a row.
Your SSD doesn't even get a chance to write its cache empty, and you have 8 files of 64GB ready again to write.
And i can tell you that this really hurt's the life of your SSD! That test as you selected is for Professional SSD's in RAID systems!

^^ what SPDIF said^^

Either that or you got a bad drive...so rerun your tests as noted, and if the results aren't much better, you should return it asap...because under normal conditions, that drive is capable of around 3500MB/s writes & 3000MB/s reads

Thanks for the clarifications all, I have run the test again at 1gb.

Big ups on the read speed, but the write speed plummeted. I ran 5 different 1x1gb tests to be sure, with settings on default for 3 of them and on NVMe SSD for 2 of them.
This is the best result I got, and it was on default settings.
This is all after defragging the disk.

ps I used 9x64gb because a youtube guide told me to, I didn't realize it was a poor benchmark.

Aaaah, you are also an defragging boy? You should read the other topic here about defragging an SSD.

That speed in write is abnormal, i also see your SDD is nearly full. I think the best here is to do a Secure Erase of that SSD.
Try to make some more space by copy stuff to another media, and test again. Just to rule out stuff. Also for best results you should do that test not as C: drive, because many other program's like a AV could interfere with result's.

Boot from another drive and do this test just as D: drive. Then we can rule out windows or program's that interfere with the result's.

Is it bad? I was just doing as another response said. I'll stop doing it. How is it bad for SSDs?

 

[SPDIF]

Don't do that anymore! Read this topic.

Regaining Health on NVME?

hey guys. i used defraggler i optimized the disk first after i did a basic cleaning of programs temp files etc... then did long defrag all sectors turned blue! to my amazement of course.... i checked health status and it gained 4 % health back! and gained speed! i used wrong algortihim...

Do not defrag SSD, period. Trim good, defrag bad bad.

The windows defragging tool only defrags HDDs. On an SSD, it runs TRIM. That's why I suggested running it.

 

[SPDIF]

Yes windows does not defrag, it just Trim's, i thought he used a defrag tool. Because he litter y said he defrag it, while windows don't do that.

 

[Thebadgamer98]

Oh okay, phew. No I just used the default disk optimization tool.
Didn't know there was a difference between trim and defrag before this thread.
Learning a lot here, thank you all so much!

 

[SPDIF]

Then it's all okay, have fun.

 

[Thebadgamer98]

For anyone interested: I returned the NVMe and went back to my 2x1tb SATA SSD setup. Thanks for all the advice!

And your money back, not a bad deal.
