Hi everyone,

I've been using an Asus VivoBook X510UF notebook for over five years now. Initially, it came with only a 1 TB HDD, but two years ago, I installed a Samsung 860 Evo 500 GB M.2 SATA SSD and migrated Windows and my applications onto it.

A few weeks ago, I noticed significant slowness on my laptop, to the point where even websites took a long time to load in the browser. I decided to format and clean install Windows 10, as it had been over two years since I last did this. However, I noticed that the installation process on my SSD took much longer than before. Even after the installation, the slowness persisted, prompting me to benchmark my SSD using Samsung Magician and Crystal DiskMark.
The results showed a drastic drop in random read and write speeds.

Initially, I suspected a failure with my SSD and considered returning it under warranty. I removed the SSD and reverted to installing Windows on my HDD, only to find it was also significantly slower than before, as confirmed by a benchmark. To further investigate, I tested an external SSD with similar results—slower speeds. I was confused and unsure of what could have caused this.

I decided to recheck everything and reconnected the SSD to the motherboard, reinstalling Windows once more. Surprisingly, this time the process was faster, and everything seemed normal again. Daily benchmarks initially showed no abnormalities, but after 4-5 days, the random read/write speeds dropped again. I continued daily benchmarks over the next few days, with consistent results.

I eventually replaced the Evo with another SSD and installed Windows on it. The initial benchmarks were as expected, but over subsequent tests, the random speeds dropped similar to those of the Evo. Based on these experiences and test results over the past few weeks, I believe this issue is not related to the SSDs or HDD themselves but likely involves another component, possibly the motherboard. I'm really not sure how to resolve this issue.

If anyone has had similar experiences or insights into fixing this issue, please share them here. Your assistance would be greatly appreciated.

Did you update all drivers too ?

Ensure TRIM is enabled and you run a garbage sweep every other month.

SSDs do not perform well when hot or near capacity.
TRIM is already enabled and 90% of the drive is free. The temperature is also normal stays around 35-38 degrees (Celsius) most of the time.
 
I am having this same issue - with two separate Samsung 990 Pro NVMI PCIE 4 "drives". I initially had random read I/O speeds on the order of 1,600,000 IOPS and write speeds on the order of 1,000,000 IOPS initially, but now they are down to 190,000 IOPS read and 160,000 IOPS write - so 85% - 90% worse. The machine is new, my own build, Windows 11, and seems to perform OK. I tried:
- turning off anti-virus
- Turning off write cache (made write speeds horrible)
- Turning off Microsoft's new "Smart App Control" (which I had accidentally
turned on -- now it is off for good because you cannot turn it back on (silly random Microsoft!)

None of those made any difference.

I saw the same kind of degradation on my old Windows 10 machine between when I installed it, and now.

Note that Samsung Magician and Crystal both now use the Microsoft tool "dskspd", and I noted that at times it was at 100% CPU utilization (so, ALL the cores on my Intel Ultra 265K CPU). So, I *suspect* that the answer lies with that tool.
