    There is no "M.2 interposer assembly", you can install the card right into the system without any extra hardware. In your photo, the connector is at the top (where the SATA interposer connects) and the screw for holding the M.2 drive is unused at the bottom. It does seem that you would have to source a heatsink but it is identical to the one used with other M.2 cards in the system.

    Hello All, I am awaiting my 7730. My plan is to put in a RAID 0 with two or three SSDs.

    My question is: Are all the M.2 NVMe SSD slots essentially the same (interface, speed, latency, etc)?

    If one were going to do a RAID 0, would there be a preference as to which slots one would use?

    Saying "m.2 interposer assembly" was a poor choice of words on my part. Long day. You definitely need some kind of caddy in addition to the heatsink. The base/caddy for the sata interposer is not compatible with m.2.

    You need to fully remove the SATA caddy. You should then be able to fit an M.2 drive where the SATA interposer was connected. Best I can tell, no additional hardware is needed besides the heatsink. You could probably get by without a heatsink even if a SATA M.2 drive is used. (See my photo in the very first post in this thread, the heatsink position is visible.)

    They are all the same speed. However, we have word that a drive inserted into one of the four slots is not showing up as an option to be added to a RAID array. (The one nearest the RAM, I think?)

    When you do, please grab me the qcode part number for the m.2 caddy. Page 44 of service manual clearly shows a caddy/base. The base for SATA interposer is actually too short for an m.2 and it has an oval strut that comes up through a hole in the center of the interposer PCB. It is like they intentionally designed it to be non-interoperable just to be difficult and make you buy a dell SSD (if they truly don't sell the caddy by itself).

    Aaron, I just cross-checked the service manuals of the 7530 and the 7730. Contrary to it's 15" brother, the 7730 does need an additional mechanical component for mounting the SSD. A component that is indeed not usable for the hard drive interposer, or vice versa.

    @cp42 , did you already fill the 3 other M.2 slots?

    Alright... I made the bad assumption that the 7530 and 7730 are the same in this regard. Someone with the 7730 will need to pull the part number.

    I'm updating the very first post with the SATA part numbers in case it is useful to anyone in the future, it should be easier to find...

    Updated dock firmware to 1.0.6 this morning. No issues with the update.
    Turned C states back on in the BIOS. It's early but I've been running for a bit now and haven't noticed any mouse or keyboard stuttering. We'll see if it lasts through the day...

    [Edit] Just a few minutes later and I observed mouse stuttering. Flipping C states back on...
    Not unexpected since the release notes only mention correcting a power issue with this update. Hopefully it solves the problem I was having where it is difficult to get the system to draw power from the dock.

    Thanks for testing - so I skip that C state test on my system
