SSDs Have Become Fast, Except in the Cloud

I would start with the LBA format, which is likely to be suboptimal for compatibility.

somehow I4g drives don't like to get formatted

    # nvme format /dev/nvme1 -n1 -f
    NVMe status: INVALID_OPCODE: The associated command opcode field is not valid(0x2001)
    # nvme id-ctrl /dev/nvme1 | grep oacs
    oacs      : 0

but the LBA format indeed is sus:

    LBA Format  0 : Metadata Size: 0   bytes - Data Size: 512 bytes - Relative Performance: 0 Best (in use)

It's a shame. The recent "datacenter nvme" standards involving fb, goog, et al mandate 4K LBA support.

it'd be great if you'd manage to throw together quick blogpost about i4g io perf, there obviously something funny going on and I imagine you guys could figure it out much easier than anybody else, especially if you are already having some figures in the marketing.
