B350M Bazooka with Ryzen 5 1600 gives poor USB write speeds and crazy CDM benchmarks

[EXTREEM_LT]

Greetings!

 

System in question is:
Windows 10 (latest update)
MSI B350M Bazooka (latest BIOS, drivers, chipset drivers from MSI site)

Ryzen 5 1600 (stock speeds).

Corsair Vengeance 2x8GB 2400MHz in dual channel.
Asus GTX 1050 Ti.
3 SSDs and 1 HDD on SATAIII, one of which is Samsung 850 Pro, about which we will talk soon, and a couple of USB flash drives (Kingston SE G2 8GB USB 3.0 and Sandisk Cruzer Micro 8GB USB 2.0).

The issue that I primarily have is that when I tried to copy music over to Kingston USB drive the speed was terribly low. I started benchmarking using CrystalDiskMark 6.0.2, and later tried other software to still have some ridiculous results. During my testing I switched between NTFS and FAT32 for the USB drives, I also switched between power plans and used MSI X Boost to "USB Speed Up" and "Storage Boost", and saw no improved results, BIOS also got updated in this process.
I then tried to test Samsung 850 Pro SSD (SATA III) and got results that should look like NVMe, but not SATA. I used USB 3 ports for testing as well as USB 2 ports, with Legacy USB Support = Enabled in BIOS. I tried both front and back ports.

So - how can I improve my USB storage write speeds? Any ideas who's the culprit - CPU, MoBo, RAM, Drivers, OS, CDM or Windows speed benchmarking method that it uses, or any other ideas?
As a secondary question - why does SSD give out NVMe results in CrystalDiskMark?
About the 1 iteration with 50MiB test sample - sorry, but this already takes ages, and running multiple tests with bigger sample would be horrible. Also - I don't have an external USB HDD or SSD to test with anything else, but USB Flash drives.

 

After writing up this post, I remembered that I have an Intel based laptop and ran CrystalDiskMark 6.0.2 and got the results that are better but still weird:

 

So, any ideas, or maybe this is even a known issue? Any help/advice is welcome.

Download the latest chipset drivers from AMD's website : https://www.amd.com/en/support/chipsets/amd-socket-am4/b350

 

The latest official one is 18.10.1810

 

The one on MSI's page is 18.10.30 which in theory is newer, but I suspect - based on the name - that it's bundle of drivers which is newer version only because some threadripper chipset (x399) driver was updated.

 

Note that some USB ports come directly from CPU and some come from chipset.  The four usb 3.1 gen1 on the back of the board are most likely coming from CPU. The other four ports (gray/black) are USB 2.0 

The other usb 3.1 gen1 and usb 2.0 are all coming from chipset.

 

The ports coming from CPU should be the fastest. Based on speeds (30-ish MB/s) I suspect you've connected the drive to a usb 2.0 port, or the SSD is running at usb 2.0 speeds. Maybe check the cable and make sure it's not damaged?

I used red USB ports on the back for flash drives.
As for SSD on Ryzen - it shows read write speeds way above SATA III, that's why I'm confused, SSD too fast, USB too slow.
I tried installing the driver from your link, however it looks like I can't install the older version.

How in Gods green earth you geting 4400mb write speed and 3300 read speed ?  Those are incorrect results.

My thoughts exactly. So CDM gives me wrong results for SSD AND I get very low write speeds on USB 3. Any ideas what might cause this?

Ok how about if you run crystal disk info ,,,,,, how is the health of your drive ?  Also can you fill in your signature so we know what rig you have so we can help you much better.

 

Also if the health of your main drive is 100 percent then you have nothing to worry about.  USB speeds can be port issues or ports tangling with each other.  A USB 3.0 should transfer at up to 150mbps .  Your SSD is 500mbps ...  So theres going to be bottleneck copying files over and what not. 

 

I suggest you uninstall any mobo drivers you have installed including usb drivers.  Clean it all up, then get the latest version of drivers for your mobo, usb drivers if necessarily.  Also latest SATA drivers.  Then let us know, also state your OS.. thx

I run Windows 10 Pro Build 17763.

Primary drive - OCZ Vertex 4 128GB - 96% Health.
Secondary drive - Samsung 850 Pro 512GB - 100% Health.
Signature updated, sorry, just started.

I updated all available drivers from MSI today including: BIOS, Chipset, Lan and Audio. Sadly, that's all that MSI provides, and Windows update doesn't offer any updates at this time as well, so my guess is - SATA and USB drivers are bundled with chipset pack.

Also - my main problem is with USB speeds, is it normal to experience 0.007-0.0015MB/s 4k write speeds?

P.S.: I tried benchmarking my other 2 SSDs and they are showing adequate results, so looks like only Samsung 850 Pro shows ridiculous results and USBs are giving me low write speeds.

Sorry to revive this, but I finally found the culprit behind these readings. It's Samsung's RAPID mode that messes everything up. Turning it off got my readings back to normal, case closed! Just thought someone might've been interested in the answer.

thanks for the update..
