An SSD shouldn't get bogged down by copying from an HDD. QLC was a mistake

@matrix@gameliberty.club unlikely but could it be that the SATA connection is what's filling up that graph? Maybe the SATA throughput is fully saturated. If you can buy a better SSD, try using it with SATA as well and see if that will work better or not.

If it still doesn't improve, buying an NVMe SSD might be the solution

@dead_man Nah, SATA is like 550ish MB/s. I'm was moving TF2 so it's getting bogged down by a combination of small and large files. QLC has abysmal random writes.
I have 3 NVME drives, 1 is an Optane drive (haven't moved my Windows install to it yet though).

@matrix How sure are you that it's bogged? When I watch these graphs while starting CrystalDiskMark, the range changes...

@WandererUber high latency, CrystalDiskMark doesn't fully cover every workload

@matrix I'm not saying Crystal Disk Mark is more accurate, I am saying maybe the disk load indicator in the Task Manager is scuffed.
If 125 MB is the maximum it has seen, it will show "100%" load, even though the SSD might be capable of more.
That's why I asked how sure you are that this is in fact the bottleneck.

@WandererUber It might be a bit scuffed, but I was copying TF2 so the high load is from random writes.
This drive has about 90GB of cache so sequential writes under that can go full speed and only then it drops to HDD speeds.

@WandererUber @matrix CrystalDiskMark usually doesn't fill the DRAM cache that SSDs need to be somewhat performant (especially QLC and MLC). If you set the test file size to a large number, you'll probably see a significant slowdown.
