Very low write speeds in NVME SSD

[X71200]

Wouldn't recommend buying into that stuff as doubtful the OP can spend an enormous amount of cash for low per GB. That stuff isn't truly worth it, never been for the average consumer.

The P1 is one drive that specifically sucks with this, newer, better drives will perform significantly better in this area. Especially if they go about using two drives, then the data would be spread and easier to handle.

Thanks all for your suggestions,, I have already installed crucial software even that reports good health, I have run all their tests and its ok as well, I have directly slotted in my motherboards primary m2 slot there is no cable involved, unfortunately its my OS drive so thinking whether to try the secure erase as its too much hassle but if you all think drive is dying I may have to move to a different drive anyway.

I feel like its windows 11 after upgrade this is the first time I am benchmarking also other than this I don't see any major hiccups as I don't any frequent writes other than downloading games.

Your drive spent quite some time thermal throttling. Try opening your side panel, pointing a fan at the drive and running the test like that again. If it is still slow we can at least rule out thermal issues.

I don't think its thermal throttling, i benchmarked with the case open, high is 63 which is still hot but ok I guess, I don't know about the driver temp 5 whether its related to SSD and if its the issue

From the tpu review of this SSD:

Without a fan, the drive throttles pretty quickly, after around a minute of full load, which is rather short. The temperature at which throttling starts seems rather low, too: only 63°C. We've seen other drives start throttling at much higher temperatures, and more gradually, which is something Crucial should consider for a future firmware revision.

So I think your drive is throttling already. Everything listed in the CT1000P1SSD is related to that SSD. The almost 90°C is probably the controller, which is extremely toasty imo.
Just opening the side panel might not be enough if there is no airflow in your room either. Also depends on where you live and how hot it is in your room. The hotter the ambient air, the worse your cooling will perform. If you have any kind of fan you could point at the ssd (even a regular room fan or something) that should drop temperatures enough to test it.

Throttling drops write speeds from 1.6GB/s to 600MB/s:

Now @depakjan is seeing write speeds of 42MB/s and he's even cleared out another 150GB since the first test yesterday.

It's not a throttling issue, performance is laughably low
It's not a free space issue, continuing to make more free space has made things considerably worse, not better.

At this point I'm tempted to say it's a faulty drive; Bootable linux from USB to confirm it's not the OS but 42MB/s sequential write is all kinds of FUBAR.
@depakjan - you have backups of anything you care about on the P1, right?

In the TPU review their controller "only" reached 79°C whereas OP's controller reports almost 90°C peak temp. It might just be a faulty drive, but I think it is easy enough to eliminate thermal issues by testing it with a fan. Especially because their read speeds are all fine but (excessive) writing is an issue, thermals jump to the top of my suspect list. Also the way I understand the first post, OP has been using the drive normally without issues for quite some time. The problems are only apparent during benchmarks, which naturally produce a lot of heat through maximum usage that wouldn't happen as much on day to day usage.

I will test once at night with my air conditioning on which will reduce the ambient temps to about 26( current ambient is crazy 31) and redo the tests, post back the results.

Yes this is my primary OS drive so cant clean it up easily, have to prepare another drive first

Get on it before the controller poops on you

Also very high quality TLC drives have great sustained speeds now, the 980 PRO is almost as fast sustained as the MLC 970 PRO.

 

[X71200]

Yeah I do have a 980 Pro, it's been a pretty solid drive speed-wise. 4k's came close around 100, 32QD boosting shoot. There are better Phison drives out now, though.

Frankly, a cheaper drive that doesn't suck, would just work.

 

[depakjan]

Dont think its the temps, temps were around 74 this time during the write test

 

[Mussels]

You need the drive cooled, free space, and TRIM ran.
74C is still too damn hot.

After thats sorted speeds might get back to normal.

You're another user who didnt fill the system specs - please do

How is this drive connected? CPU lanes, chipset lanes? It shows 3.0 x4 which is good, but if you're overheating on congested bandwidth with a full drive it all piles on together.

 

[chrcoluk]

Just researched the drive, after I read the QLC post.

I think you are writing direct to QLC bypassing the SLC, looks like for whatever reason SLC hasnt been cleaned.

 

[depakjan]

This is exactly my conclusion, i have no clue how to force clean the SLC other than to full format the drive

i notie recently. with how i set up my pc for the third time. the 1 m.2 under the fattttt evga 2070( thick boy one) is making the controller run way hotter now. due to cpu cool massive size. air not flowing correctly.
i have some 3d metal printed hs i will be adding onto m.2 controller .
but i will say nice spot on temp thing. most people dont even talk about that.

 

[eidairaman1]

Trim should of cleared the "cache"

 

[Mussels]

This is exactly my conclusion, i have no clue how to force clean the SLC other than to full format the drive

On most QLC drives, SLC uses 3x the space - as the drive fills it cant use the cache any longer

They only use one of the three layers (rotating through them) and speeding things up, but once it's too full there are no empty layers to ignore and all writes are the slower TLC method

 

[AleXXX666]

Had the same thing happen to my 970 EVO. Basically your drive is dying or software issue.

yeah, look at these written TB and health. plus it's not top-notch ssd.

To be fair, my drive had 364TBW on it.

i know it's ok, i just prefer to replace 'em when they hit about ~20-30 lol

They have so much more life than that. We're at the point where a single flash chip on an NVME is rated for 150TBW. Just practice backing up your files and you'll be fine.

During our test benchmarks stress tests with a high-stress workload, we monitor the SSD temperature. As you can see the secondary internal sensor even reaches 89 Degrees C when the product is not cooled by air or a heatsink. source

The P1 will need another firmware update as there is something going on with the SSD loaded up with data and a perf drop. Also, you have a huge cache for many gigabytes of writes, but once the buffers run dry, write performance will cave in bigtime. source

Seems this is normal for this drive.
