> Since then, several NVMe instance types, including i4i and im4gn, have been launched. Surprisingly, however, the performance has not increased; seven years after the i3 launch, we are still stuck with 2 GB/s per SSD.

AWS marketing claims otherwise:

    Up to 800K random write IOPS
    Up to 1 million random read IOPS
    Up to 5600 MB/second of sequential writes
    Up to 8000 MB/second of sequential reads

This is for 8 SSDs and a single modern PCIe 5.0 has better specs than this.

Those claims are per device. There isn't even an instance in that family with 8 devices.
