NVMe is a logical device interface specification for accessing non-volatile storage media attached via a PCI Express bus. The NVMe 1.3 specification has been published, and it introduces several new features:

As with previous updates to the standard, most of the new features are optional but will probably see widespread adoption in their relevant market segments over the next few years. Several of the new NVMe features are based on existing features of other storage interfaces and protocol such as eMMC and ATA. Here are some of the most interesting new features:

Device Self Tests
Boot Partitions
Sanitize
Virtualization
Namespace Optimal IO Boundary
Directives and Streams
Non-Operational Power State Permissive Mode
Host Controlled Thermal Management

    Could it be filled with malware. Hidden malware. Non volatile malware. Malware that self installs. Persistent malware that survives device erasure.

    It's not mature technology until it is used for malware.

    You could fill it with whatever you want.

    You already plug in all sorts of things [wikipedia.org] into the PCIe bus (without knowing what you are doing) so why start worrying now? Most people don't even realize their shiny new laptop or netbook has at least one PCIe slot, and wouldn't know WHICH ONE they had if it bit them in the ass.

    There are so many new competing PCIe port standards [wikipedia.org] that any machine already equipped with one is obsolete before shipped.

    And they are all talking directly to the bus and there's plenty of room for malware and has been since the first day you cabled in a hard drive to your old fashion ata drive controller.

    No, you are mistaken. I've always had this sig.

      Time for some I/O MMU such that devices don't get unrestricted access to main memory or CPU?
