The same issue like all the other folks here, sadly it looks when the drive is around or above 50%, the write speeds get from 4-5k to 1k, that's unacceptable behavior and we as customers should have zero tolerance for accepting this, either allow folks get their money back or fix this, this is a global issue and there's no a SINGLE person that doesn't face this issue, so please don't put the blame on the customer in any way.

Motherboard: x570 TUF gaming wifi
CPU: 3700x
Memory brand: G.skill
Memory model: Trident Z RGB
Memory capacity: 32GB
Memory speed: 3600 / PC4 28800
BIOS Version: 2802
Windows Build and Version: Win 10 Pro 64 bit (2004)
MP600 Capacity: 1TB
MP600 Firmware Version: 11.3
Using drive as OS or storage? OS
Which M.2 slot: Main slot
Stock heatsink on MP600: Yes


Above 50% (or around it e.g. 46-49%):
- Writing at 1k speeds

Below the above:
- Writing at 4.2k speed.

What I tested and my settings so far?
- CDM with highest test counts (9) test size @ 32
- BIOS default settings + PCI-E m.2 on gen 4 to ensure Mobo doesn't switch weirdly to anything else.
- Power plan on highest performance - also quick startup disabled as recommended (didn't help ofc).
- Switched to other m.2 slot - didn't help ofc.
- Clean OS and then refill of the same above 50% - same issue.
- Testing without any side apps by running safe mode - didn't help, ofc.
- Disconnecting other SSDs, leaving this alone - didn't help, ofc.
- Making sure everything is up to date, firmware, BIOS, OS, everything related - didn't help, ofc.

So to me, after reading this thread, I'm in a position that I see no clear resolution, people have been calling out for help for over a year, and we the customers are the suckers here it seems, I have no willing into getting a replacement if I'll face the same issue and your legal excuse of "SSD degrades by the time" is BS, a simple test would be to fill it up above 50% and prove the point again and again.

What's the solution here folks? Are you going to keep darg everyone's feet for any longer or allow anyone who's owning this to return this for a full refund?

Edit: After more continuous testing, even at 30% usage of the disk, the performance is about 1k writing speed. temperatures are OK as-well, just looks like a complete fault device.
I did notice on page 7 of this post that someone received a new RMA package (which is a yellow package instead of normal white like mine) and the performance seems to be better.
I did create an RMA ticket (#2003692199) about this, hope to receive a replacement, to begin with, or even a full refund if possible.

Cross-posting this in threads as a warning.

Whatever you do, do NOT update your firmware.

Please note that I have even decreased my storage utilization between the two tests in a manner that should have had a positive effect.

WTF

Also I have stupid idea that the speed issue is somehow related to if its windows drive(c bootable) or storage drive. Because i lose speed on windows but not on storage (i have 2 same drives)

yes same to me. I installed additional drive (WD SN750) Cloned the MP510 and now i am using WD 750 as System drive. The Corsair, which was poor of data transfer is now good. Strange

The same thing happened to me. I changed my slow MP600 for a Samsung 980 Pro, and when using the MP600 as a data drive only the speed is consistent "as advertised" or very close.

Hi, some news from me. I changed CPU from 3700x to 5950x and strangely all my drives (2 of MP600) now have advertised speed at moment (no windows reinstall). It might be CPU problem maybe?
