M.2 Nvme SSD low RND 4k Q1T1 performance

[aegir221]

I did a KDiskMark benchmark on my SiliconPower A60 512GB nvme M.2 SSD and noticed that it has really low Q1T1 4k performance. It reads ~ 5 to 10MB/s but should be anywhere from 70 to 100MB/s. Even my MX500 crucial Sata6 shows 70MB/s on Q1T1 4k.

Anyone had such a glitch?

First, reboot please.

Ok I did that but the results are the same. I am going to give it a rest for today… It isnt bugging me much.

Ideas:

1.1 Maybe I f* up my partitions or patition table. I have the SSD split to brtfs system / root drive and system unrelated partiton with btrfs.
2.1 Or I damaged the M.2 drive installing it last year. I did some trickery because I did not have the proper small tigh thread screw to mount the M.2 in place. Maybe it has bad connection… otherwise the drive should be okay.

---------> 3.1 Another idea. Can anyone bother to share their KDiskMark result on their System root drive? Preferably M2 drive.

It could also be a heat problem. I have found that with an external NVMe, the performance drops rapidly until I cool it with the help of a small USB-Flower-fan.

Cost ~ € 6, consumption 1 watt. Not nice but effective.

Used to back up all my data from my home server.
Always on hand in case the place burns down or a flood washes everything away.

I know you asked for M.2 but hey Nvme ain’t bad either.

Well to be honest, that’s the only drive I have so…

I believe mine is Nvme too - the m.2 Nvme slot.

I apologize I don't know why I thought M.2 refers to the sata ssd.

MX500 results:

I'm going to change the Nvme SSD probably. I might leave this SiliconPower for another system.

The real solution was ---> Erase the drive of all partitions, then reinstall Garuda and just use the default partition option ---> Use Entire Drive. I swapped 2 flies at one with this cause I wanted a bigger system partition.
Great, now I don't need another Nvme drive.

Results.

Guru3d SSD benchmark results as comparison. Similar Nvme M.2 drives here, some PCI-E Gen4. The drive is behaving as it should. (CrystalDisk mark has the same tests and layout) My RND4k Q1T1 results ranged from 46 to 60 which is to be expected.
