Slow ssd?

[Flux Azreal]

My Read speed: 512

My Write Speed: 320

(With Rapid) 

 

 

everything seems good tbh but when im copying a folder to another folder its sorta slow 

shouldent i be  like copying the file like a lot faster? 2.41mb/s seems a bit slow for an ssd

 

CPU: AMD Ryzen 5 1600

If you transfer a file larger than the buffer cache the speed will slow down. That could be the issue. You might also have it plugged into a SATA port that shares a PCIE lane.

Run all tests and post a screenshot of the result.

It looks as though they might be transferring lots of smaller files which is why it's slowed down. In the screenshot it's a Python file so it's likely no more than a few MB.

Small files transfer slower. With 4K QD1 random IOPS of around 10,000, which is the rule of thumb for a good SATA SSD, you'd be looking at about 40 MB/s.

 

Still, 10 MB/s seems pretty low and 2.4 is definitely strange.

Those numbers are fine, in fact more than fine.

 

As explained, I think the problem is simply that you were copying many small files. Because of how SSDs store data many small files can take longer to write meaning transfer speeds are slowed down while Windows waits for the cache to be emptied.

 

It's just a quirk of SSDs.
