Hello everyone,

I have Kingston 512GB (i dunno what type) and WD Black SN750 1TB on my laptop.
My laptop is acer nitro 5 ryzen 7, it have 2 m.2 nvme slot and 1 sata hdd

If I check on crytaldiskmark in the beginning of my startup the speed is normal.
Kingston (2800/1500) & WD (3400/3000)
but after I try it one more time speed is drop.
Kingston (1700/800) & WD (1400/1300)

Im not sure if this case is normal or any problem with the software/nvme temp
The startup temp is 55-59, and the second attempt is 62-64

Use Task Manager and Reliability History to observe what the system is doing. Use both tools but only one tool at a time.

Look before running crystal disk mark and then again afterwards.

My thought is that some other process is getting launched after the laptop has been on for a few minutes.

Look in Task Manager > Startup

Also Task Scheduler. Look for some trigger that launches another process.

Another tool to help is Process Explorer (Microsoft, free):

Overall objective is to discover what changes between the startup and the second test.

nothing change on the task manager or resource monitor
But i try to add my nvme a heatsink and make it cooler. the result is my speed back to normal. it still a slight drop about 100MBps but its ok.
I'm not sure if the problem is the composite temp. but now its normal.

Thanks for your suggestion btw
