Question SSD/M.2 and AMD motherboard b450m performance issue

[daniel4ing]

I have a Prime B450M-A with a Ryzen 7 3700x, which has 6 Sata6g ports, 1 NVME PCIE M.2 slot, and 32GB Ram.

When I originally bought the computer, it came with a HDD and an SSD that were plugged into the Sata 5 and 6 ports. Since then, my hard drives have started to fill up, so I bought an M.2 and another SSD.

I first started to add the M.2, but when I use that I have to move the HDD and the SSD cables to one of the four other ports, which will result in performance loss. When I take the M.2 out and restore the HDD and the SSD back to Sata ports 5 and 6, it goes back to performing normally. When I add the new SSD, and use one of the other 4 remaining Sata Slots, the same performance drop occurs (as suggested by the manual),

So, I feel that the Sata6G 1-4 ports just act differently to the Sata6G 5-6 ports.

Latest drivers for everything. Is this a power supply issue? Is there a BIOS setting that I'm overlooking? I've been messing with this for weeks now, and I just can't figure this out.

In some cases inserting M.2 SSD interferes with couple of SATA ports, should be explained in MB manual.

Oh, I thought I explained that part. I did what the manual set and swapped the HDD and the SSD to the Sata6G 1-4 ports, so that ports 5-6 would be freed up for the M.2. Which is originally how I found the micro stutter.

You failed to say what performance loss you encountered, I thought it was about disk system. Do you have any games or programs with that micro stutter installed on HDD or do they access it often ? When you install a much faster disk like NVME discrepancy of speed with a relatively slow HDD becomes more apparent. That has nothing to do with ports HDD is plugged in and power.

Games that normally run smoothly just become a stuttering mess. Music starts to crackle. Windows actions feel sluggish. Videos don't play as smoothly. Everything feels like it's on 85%, and it just feels that the computer is struggling to keep up with anything that's happening. I haven't tried adding the M.2 and the new SSD in together at the same time, since the machine is already stuttering if I put either the M.2 or the new SSD in the machine.

Most games and work were installed on the SSD, but I've also tried to run a game from the HDD and that gave the same result.

So, if I understand what you're saying, there might be a chance that I just have to copy my windows from the HDD to the new SSD and replace the HDD? Little confused, since the HDD and the old SSD have played nicely together all this time.

I have copied the HDD drive to the M.2 before, but left the HDD in the machine. Booted from the M.2, also still with micro stuttering. I guess I should have tried removing the HDD at the time. (fixed, typed SSD, even though it was M.2),

I replaced all SATA disks of which one was HDD with all M.2 NVME for similar reason, Every time HDD was accessed from Windows on fastest NVME it would spike to 100% usage and affected everything else.
If you left other drives connected during windows installation it's possible that part of it was also installed in HDD so it accesses it often.
It's best to install windows and any other OS while only one disk is present to avoid mix ups,
You should be able to see if that's the case in any disk manager.

There should be NO performance difference between the various SATA ports.

Copied the 50GB SSD info over to the 2TB SSD (which gave stuttering before when I added it to the Sata6g ports 1-4), which has now become my C drive (Sata6g port 5). The 2TB HDD is still in there (Sata6g port 6). Machine runs extremely smooth again. Micro stutter is gone.

I wanted to add a 2TB SSD, but I guess I should just be happy with the 75% result instead. Still confused.
