Jeff - are the disks slower (but bigger) than the i3 versions? It looks like the IOPS and throughput are lower at the top end (looking at the two release pages

  You see something greater than 2-million IOPS?

    Yes - the announcement for the older i3 instances (https://aws.amazon.com/blogs/aws/now-available-i3-instances-for-demanding-io-intensive-applications/ https://aws.amazon.com/blogs/aws/now-available-i3-instances-...) claims 3.3M IOPS (presumably on the largest size, with 15.2TB) So it looks to me like these are larger, slower drives?

      It used to be 3.3M IOPS on 8 SSDs and now it's 2M on 8 SSDs but significantly cheaper; I wouldn't be surprised if they've replaced MLC with TLC.

        8 TLC drives could easily hit 3.3M IOPS before... i3 have 8 1.9TB NVMe SSDs max, right? A 2TB P4600(TLC NAND) has 610,000 random read IOPS max, so that's 4.8M IOPS right there. A 7.68TB P4320 has 427,000 random read IOPS max, so that's 3.42M IOPS right there over 8 drives... Maybe they went from TLC to QLC with these ones?

      This seems to be confirmed by the IOPS numbers in the documentation: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/storage-optimized-instances.html#i2-instances-diskperf https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/storage-...

  I am supposedly on a stay-cation this week. I'll ask the team to check this thread.
