    I am curious how the dual SAS interface is use - is this for performance and double transfer - or the crazy idea to work redundant servers or such.

    Just FYI, I have dual 36G 15000 rpm SAS drives on my Supermicro - setup original as Raid 0.

    If these SAS were setup for performance in dual configuration, I am also curious what a Dual SAS SSD drive would be like.

    Dual-port SAS drives are used both for fault-tolerance (i.e. HBA/port failure, still has access through other port) and the ability to be device addressable by different storage controllers.

    That sounds logical for fault-tolerance. My supermicro has hot swappable drives and such and this would take it to next level

    Dual SAS is entirely for redundancy - all storage arrays worth anything whatsoever have two controllers, that can fail over from one to the other. Dual ports mean that every disk always has a path to both controllers at all times.

    The chart says the interface is "SATA 6 Gps."

    Never got these helium drives, the gas is inevitably gonna leak. That sounds bad.

    The helium has nowhere to go. You are right that helium has the tendency to escape. But the other gasses need to replace it. And of course the enclosure is gas proof with an under pressure I asume.
    Yes it is leaking kind of per definition. It won't empty itself (and become near vacuum) in the warranty period. Probably in the order of hundreds of years.
