[SOLVED] SSD very slow write speeds, read speeds fine

[Bubble_Double]

So i got a prebuilt computer and it had this cheap ssd on it. At first it seemed fine but now i noticed that windows would stutter a lot when i was installing something on the SSD. Then i ran a crystaldiskmark test on it and the write speeds were slower than my hard drive's (58 mb/s). I asked the SSD maker ("kingfast", not very fast) and they haven't replied yet. On their site they show write speeds at 400 mb/s (https://www.kingfast-ssd.com/shop/f6-series/f6-series-pro/kingfast-f6-pro-series-240gb-sata3-ssd/). I also tried filling up my ssd to see if the speed would drop down again, but it stayed the same.

Is write cache enabled for that drive?

Try a different SATA port.
Try a different cable.

Otherwise, it might just be that drive.
"Kingfast" is 3rd rate, at best.

Run CrystalDiskInfo, and let us see how many power on hours, and total bytes written it has.

Ill try, but could formatting the drive fix anything or is it not worth trying?

Formatting and reinstall probably won't do anything.

Thanks, here's crystaldiskinfo (i got the computer around 2 months ago)

If anyone reads this post in the future, secure erasing the SSD from my BIOS fixed the issue. Now I'm getting the write speeds i was supposed to have.

Hi

I do have same issue with my Dell Desktop (SSD Kingston A400 SATA), still working with you? having the full speed as write/Read (especially write) after secure erase and reinstalling windows?
