Hidden downside to its price I guess. it could be its got an slc cache of about 26gb and then it slows down to 615mb/s if its similar to this one.

Two choices:
- buy more ram as it seems the cache is 1/16th of your ram size at its maximum size. No idea what yours is
- You can (possibly) make it bigger - depends on its current size
before you make it bigger, back up the registry first
To do a backup of the registry, press Windows key + R and then on the run box type in there regedit and press Enter or hit OK and when the Registry Editor opens click File > Export > Select the location of the registry save file > click Save
and to restore it from your saved registry file, locate the file that you have saved and then right click on it and click Merge and a confirmation message will appear and then click Yes and this should restore the registry
and another way to do it is via the Registry Editor and then go to File > Import and locate the file that you have saved and click Open to restore it from there.

I would also create a system restore point
type "restore" then open "create a restore point"
create a new Restore Point now for C-drive
Here's how to increase the HMB size:
Open Registry Editor: Press the Windows key, type "regedit", and press Enter.
Navigate to the key: Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorPort.
Create or modify the DWORD value:
If the HMBAllocationPolicy key doesn't exist, right-click on StorPort, select "New", then "DWORD (32-bit) Value", and name it HMBAllocationPolicy.
Right-click on HMBAllocationPolicy, select "Modify", and enter the desired value.
Valid Values:
0: Disables HMB.
1: Sets HMB to the minimum size specified by the SSD firmware.
2: Sets HMB to the maximum size, potentially up to 1GB or 1/16th of system RAM.
3: Enables device-based usage, allowing the SSD to manage its own HMB allocation.
Restart your computer: Changes to the registry require a restart to take effect.

HMB already uses ram as cache
How full is the drive?
mine need to find a purpose
seems the cache size of my 4tb model is approx 442gb
