2TB Slow disk performance with M4 Max MBP

The higher scores are possibly using a benchmark with a much smaller sized file to measure the transfer speed.
In that case then the storage system cache speed is being measured, not the actual SSD NAND speed.
That needs a much bigger file size.

No. I don't have one. I'm just commenting. I don't think I've ever seen numbers like those. That's 6 gigabytes per second, hardly slow.

I don't have a photo on me, but my 2TB 16" from last year gets the same speeds. These speeds are appropriate to the SSD. Higher SSD speeds require 4TB and 8TB.
Also to note, this speed is identical to the 2TB Samsung 990 Pro SSD.
The fastest speeds are with >= 4 Tb SSD. The reason is more storage is connected to more bus, increasing throughput.

As reference, I have a 4TB M4 Max, I get around 7300-7340 read, 6000-6150 write. This is with all my apps opened.
