Slow SSD performance in a mini-pc

[Heckboy]

Hello, I've been using a MeLe Quieter3q mini PC for a while with a Crucial P3 Plus 1TB in the NVME M.2 slot. I've recently ran into performance issues due to slow drive speeds. Running CrystalMark, the result are hilariously bad. I've check a few things recommended online, like write cache setting etc, but nothing was out of order. Anyone has any ideas where I should look to resolve this?

From what I understand, these min-PCs have a PCI3.0 nvme. The write scenario is basically an app recording a video file. Cache filling up definitely sounds like it could be the case, since it the slowdowns are periodic. I can free up the drive and try benchmark again. I was just expecting a bit more than the 1/10th of the declared write speed.

Emptying up the drive brought the numbers back up quite a bit. Checked my fast ssds and fuller partitions are cooked as well. Did not realize it could get this bad, will be more careful about this in the future
