Also, define "random SSD" in your laptop.

Is it running in RAID maybe?  That's a Samsung PM961.

Why? OP matched the LTT test exactly. 4K to 4MB, 256MB File Size and Queue Depth of 32. Changing the file size wouldn't be a like for like comparison.

then it could be some bug.

i thought the files are already cached in the dram, that explains the almost dram-like speed.

But is a 128MB cache and the file size is 256 with bypass write cache.....

I'm so confused......
