Slow HyperX write speed

Hey all!

Need to ask you all about the following HyperX SSD issue. The thing really baffles me.
It’s a regular 120 Gb Kingston HyperX drive. No Savage. About 8 mnths in service now. Worked fine so far, been happy with the HDD->SSD technology transfer in general. Windows 10 boots fast, the overall feeling has been more than just fine so far. Yesterday, just out of curiosity, I fired up some SSD benchmark apps. Just to see where we’re at.

The numbers which ensued from the test shocked me a bit.

Now, as the picture shows, 77 MB/s SEQ write is downright bad I’d say. Dare to say, way below the declared writing speed.

My WD Black per instance, transfers 90+ MB/s during the same test.

Really, don’t know what's wrong here. both BIOS and W10 AHCI mode are on, using native AMD drivers (latest Catalyst chipset available). AMD’s FX 8320, Gigabyte 990XA-UD3 with 8 gigs of RAM.

I have the same SSD running in my older notebook with SATA II technology & . The notebook due to the chipset limitations does nearly 130 MB/s.

Thank you for your attention and thank you for your assistance.

Hi.

Yeah, your seq write looks a bit low. Keep in mind you're using AS SSD and CrystalBench, both use incompressible data to test the speed.

According to the datasheet for your drive (http://www.hyperxgaming.com/datasheets/SHFS37A_en.pdf):

Incompressible data transfer (AS-SSD and CrystalDiskMark) : 120GB — 420MB/s read and 120MB/s write

So you should expect 120MB/s seq max, using either of those apps. Why you're not reaching that, I don't know. Is the drive almost full? Is TRIM working? Is it a bad firmware? *shrug*

Sorry I couldn't be more help.
 
Hey, thank you for your answer.

TRIM is on with latest firmware. Got some 80 Gb free. Tried 0fill benchmark yesterday. I was able to get declared results with no problems at all. This primary test however, still makes me wonder. How is my old laptop able to hit the 120 MB/s mark and this desktop machine is not is still unclear to me.
 


That's a good question. First I'd ask if you're using the literal SAME drive - removing it from one and trying it in the other?

I'd be curious on those results, vs two different drives having different usage patterns over time.
 
Well, I've been giving that swapping idea some thought as well, but decided not to do it in the end.
This SSD I'll put into second laptop at home and get me I believe a new Sandisk X400 for the desktop machine.

Thank you all for your effort.
