We did a today (30MAR2022) speed test on the internal SSD of the latest Mac Studio with M1 Max chip and the write speed was somehow below the PCIe4.0 par. It's the same limited WRITE speed issue that M1 chip has been having for quite some time now. The WRITE speed below is just a little faster than the speed of PCIe3.0.
What SSD was used in this test?
