Question Slow write speed for Samsung EVO 970 Plus 500Gb SSD m.2

[Gilavar]

I installed a newly bought Samsung EVO 970 Plus 500Gb SSD m.2 and did a benchmark and it showed that my write speed is slow. I saw the tests for the same SSD and write speed for q8t8 should be over 2k+ while I have 800 only. What could be the problem? Is my speeds even good for my computer setup and normal for this SSD?

also I have high Read Access Time (0.40 ms) instead of (0.25 as shown in reviews and tests)

Being the C drive (the OS) can have a significant impact.
Not only is it doing this benchmark, it is also doing all that OS stuff at the same time.

I don't think it should cut write speed in 3 times. Besides I just compared ordinary users' screenshot for the same SSD model and they got C: on that SSD drive too. Speeds are 2k+ (or at least 1900) for 4KiB q8t8.

Also I tried pushing TRIM to SSD and then restarted my computer. Turned off any software in background (including my antivirus). Still 4Kib q8t8 write speed is 914 Mb/s. Not even close to 2k.

Initially, you had stated:
"and write speed for q8t8 should be over 1k+ while I have 800 only. "

The diff between 1k and just under 900 is not that great, which is what my statement was based on.

Now...if it is supposed to be 2k+, and you're seeing under 900...then that is a major diff.

I have the same drive. 970 evo plus 500GB. I tested it once and I saw that I had the same low speed as the OP. I closed down Chrome and did the test again. You're using an older version of the software. Try using the latest one.

Thanks. I didn't even know the new version of Crystl Disk Mark was available. Now the test result is

Those are great readings compared to mine. I have 3275/2650 on Seq Read/Write on the 970 Plus
