My nvme was been limited and it works at 100mb/s write

[SylveonTM]

Cpu: I5 8400

Motherboard: H370 Aorus gaming 3

Ram: 16gb DDR4 2400mhz

 

I have 2 nvme "XPG Spectrix S40G Gen3x4(3500mb/s reading 3000mb/s writting, this one have windows installed)" And "Adata Legend 800 Gen 3x2(3500mb/s reading 2800mb/s writting but i have it limited by a x2 slot to 1500mb/s and 1500mb/s)"

 

A few days ago I noticed some slowdowns in games when loading maps or even images of objects, so I started testing with crystal disk mark and saw that they were working with very low reading and writing speeds. Both nvme

 

I try EVERYTHING, Download the adata toolbox and do trim, delete stuff, Reset bios, Update windows 10 to windows 11, change powerplan to performance(on w11 i can't change it). The limitation of the Legends 800 has been solved and it is now working at 1600mb/s reading and 1500mb/s writing, but the xpg is still limited

 

I don't know what to do and I'm worried, I don't think the nvme is dying, it has 28tb written and crystal disk info show everyting is ok. The maximum temperature reached working at 100% is 42cº

Drive full or close to maybe ?

80gb free of 512gb.  It has been fuller than that and there was no problem.

check how is the write buffer cache in disk management set.

Update, i clean up some GB of space (like 80gb, the disk is now 64% full) and the reading speed is ALMOST normal, the write still very bad but have and impruve.

 

Now I'm really out of ideas to try.

im in disk management, How do I look at the write buffer cache?

looks good for the buffering. 
So it's just that the pSLC buffor wasn't working, as not enough free space available.

Ps. try to retest with larger samples, and with fewer repeets, 
As for the solution, well the quiqest is to "secure erase" the SSD (deletes all files on whole SSD). The SSD is fast on writes, when it's empty

but that will delete everything...

So the only solution is to formatting the system?  The legends 800 had been fixed somehow, with 90% in use it writes faster than the xpg which is better.

 

Did the test of 3 cycles of 8gb and give similar results.

formatting and then TRIM-ing can help, but the ideal solution is to "secure erase" it, as that's the only option for erasing ALL of the data.
And returning the SSD to a empty state.

XPG Spectrix S40G ( Realtek RTS5762 (2-core, 8-channels) + DDR3 + 64l / 96l TLC micron ) it's OK SSD, but not really groundbreaking, especially in 512GB variant.

the legend 800 have multiple hardware versions, so hard to tell.
