Concept Product CP121-8 x EDSFF E1.S NVMe SSD (9.5/15mm) Mobile Rack for External 5.25" Drive Bay

If you have any other question, please feel free to ask. :)
Will you be offering double-width latches to support these 25 mm SSDs? I could always leave gaping holes in the front, but that looks bad.

(1) It is unlikely to fit 22110 M.2 SSD on such adapter due to dimensional restriction. Would this be a concern to your application?
Agreed. There is no way M.2 22110 can be adapted for E1.S. The E1.S PCB footprint itself only has clearance for less than 100 mm of “icing” on the “cake.” It might be physically possible to hack an adapter that puts the entire M.2 SSD within the bounding volume of the E1.S form factor, but it might be out-of-spec if it’s even physically possible.

EDIT: If this is any indication, M.2 22110 would likely encroach on the space reserved for the latch:

The standard-set placement of the mounting holes on the PCB limits how close to the card edge the M.2 connector could get. The remainder of the “extra” space at the latch end of the PCB is surely less than the 30 mm needed to accommodate M.2 22110, unless an opening is carved out of the latch area to permit extending past the volume of what’s defined for E1.S.

Since I have many M.2 SSDs in the 22110 format
I’d call it quits on 22110. I found out a while ago that the market absolutely hates 22110. There is very little out there that will accommodate them. After looking around myself, I stopped buying 22110 SSDs, and I’ve pretty much written them all off. There’s still a consolation for your M.2 needs: ToughArmor MB873MP-B V2, though it’s limited to PCIe 4.0. 🙂

Mine will be sitting in their boxes until I can find a suitable home (a compact bus-powered USB4 enclosure) for them.

Hi LiKenun,

Thank you for sharing these information.

Since it is not a formal application, I personally think there is unlikely enough market demand to develop a double-width version.
Unfortunately, using the tray for CP116 (25mm E1.S) in CP121 will still leave nearly 6mm gaps in front.
 
1. Since I have many M.2 SSDs in the 22110 format, it would be great if I could use them with this product as well. However, I also have other application scenarios for them if they don’t fit in an emergency. It wouldn’t stop me from purchasing, but it would make the product significantly more versatile.


2. Because I have many of them, and I can also use them to build a delete/clone workstation for all client and server SSDs. Additionally, it would be easy to install PCIe Gen 5 M.2 SSDs with more than 10 watts of power consumption for better cooling.


3. All 8 slots. Corresponding adapter cards and 4x MCIO8 cables are already installed in the chassis.
Hi blackstone,

Thank you for answering these questions. We will take these into consideration in our development evaluation. Stay tuned:)

There’s a secondary (DIY) solution that should be nearly acceptable: joining two latches using a dowel screw at the hinge and/or inserting a flat neodymium magnet in between to bind the two latches together strongly. The former solution could work for either the hinge or hook, but not both. The latter solution would be subject to variations in flatness of the surfaces and strength of the magnets. The magnet would likely be better for the hooks if the binding strength is enough to force both hooks to move in unison. Neither should result in irreversible change to the latch.
