Re: Thinkcentre m910s with M2 SSD adapter and 1 TB SSD won't work?

One quick question.  Will the same strategy and mounting bracket work in an m710t?  I know I need to use an NVMe m.2 ssd (planning to go with the samsung 960 evo based on recommendations here) but I want to make sure that the mounting bracket shown here is the correct one for my machine before making the purchase.

Will this work on the M720 SFF?

Re: Thinkcentre m910s with M2 SSD adapter and 1 TB SSD won't work?

I don't know about the M720s SFF case situation and compatibility (or even need for) any optional part in order to install M.2 card.  Very shortly I will discover about the M920t tower case situation as I'm about to open my newly delivered M920t in order to install an M.2 card, and I had actually ordered this very 4XF0P01011 part thinking it was both necessary and compatible.

 

However the January 2019 edition of the "Accessories and Options compatibliity matrix" specifically for ThinkPad and ThinkCentre" seems to suggest that this part is only appropriate for the M710t and M710s, as well as the M910t and M910s cases:

 

 

Does not seem to be applicable to the M720s/t or M920s/t cases.  I will discover shortly why that is the case at least for my M920t.  Perhaps they now deliver the newer cases with the off-motherboard M.2 mounting bracket pre-installed at the factory so that ordering it separately as an accessory is no longer necessary.

 

But if that were the case, why are you asking about it for your M720s?

 

I'll have the answer for the M920t very soon.

Thanks! Asking because we bought a few of the 720 SFF and it seems to be a pain to get to the m.2 and not even sure how to.  I posted a Q below.

Re: Thinkcentre m910s with M2 SSD adapter and 1 TB SSD won't work?

Ok. Naturally, the Lenovo "Options compatibility matrix" is INCORRECT!  How come they can't keep their documentation up to date?  It's dated January 2019 and it shows the latest M920/M720 models as columns, so why didn't they bother to put in marks in the appropriate cells so that users would know they need that part and it's ok to buy it???  GRRRRR.....

 

So it turns out the M920t case (and in all likelihood the M920s case as well as the M720t/s cases as well) DOES REQUIRE THAT VERY SAME BRACKET, the ThinkCentre M.2 SSD Kit  part #4XF0P01011.  Of course it does!!!  And fortunately I had actually ordered it in advance, believing it was necessary... AND IT WAS!!

 

And of course Lenovo does NOT pre-install extra mounting accessories for drives and other items that you don't buy from them with your order.  You either have to opt-in (e.g. for extra empty 2nd 2.5" drive bracket to be factory installed) even if you don't buy the primary part (e.g. you don't actually buy a 2nd 2.5" drive, so that the factory installed bracket just sits empty until you might someday make use of it).  So where the M.2 SSD mounting bracket snaps into the metal chassis just off that corner of the motherboard, well it's simply empty from the factory if you don't buy an M.2 SSD drive from Lenovo.

 

Anyway, this is now the second machine I've added my own M.2 SSD drive to (M910t before, and now M920t), so I finally have figured out how to quickly install it... SINCE THERE ARE NO INSTALLATION INSTRUCTIONS WHICH COME WITH THE PART!!!  There are two plastic plug-pins which you push down into the two matching round holes at the end of the bracket.  These plastic plug-pins replace the usual tightening screws which are normally used for M.2 drives, typically screwing down through the semi-circular cutout at the end of the M.2 drive and screwing into the screw-hole typically present on motherboards.  Since these plastic M.2 SSD brackets from Lenovo are installed 90 degrees offset from the edge of the motherboard (out from the motherborard and onto the metal of the case) there is no screwhole for tightening.  So that's what these push-pins do.

 

So first, push both of these pins into the two holes in the plastic bracket.  One is for the M.2 storage slot and the other is for the M.2 WAN slot.  The bracket supports both of these M.2 cards, if you make use of both connectors on the motherboard.  Then insert the four teeth on the underside of the plastic bracket into the four matching slot/notch openings in the metal of the case right there.  Then push the bracket up, and the teeth will snap locked inside the four slots of the metal case.  It's now solidly secure.

 

Then insert the M.2 storage card (and the M.2 WAN card if you have one), carefully inserting the teeth into the M.2 socket on the motherboard (notch to the right for NVMe card) and push in so that it's all the way inserted.  The other end of the M.2 card will be swinging up in the air freely.  With one finger hold the end of the card down, and position the half-circle cutout notch for the supposed tightening screw over the matching circular opening at the top of the plastic push-pin you previously pushed into the hole in the plastic bracket.  Attached with a slim piece of plastic to the push-pin which is currently in the hole in the plastic, at the other end there is a thin pin.  You bend the plastic/pin up and down (i.e. 180 degrees) and push that thin pin into the matchine pinhole on top of the push-pin you had previously pushed into the hole in the plastic bracket.  It will snap into that hole, and now everything is held down securely.

 

The M.2 card is now "fastened", through this plastic push-pin into the hole in the plastic bracket, and then with the attached think pin into a hole in the top of the push-pin.  All of this replaces a simple screw, but it works.

 

Anyway... YOU NEED IT.

Thanks!! Honestly though wouldn't the below just be easier? Would it work? Would it make the ssd slower?

That PCIe daughtercard is the way M.2 was implemented for older machines which didn't yet have true M.2 connectors on the motherboard.  The only downside is that it takes an expansion slot, but if you have a spare slot then it's not an issue.  But you must use the "negotiable x16/x4/x1" or "x16" slots, because the full-speed M.2 drive uses four PCIe lanes.  You obviously can't put it in an x1 slot.

 

So assuming you put it in a PCIe slot that was at least x4 speed, the result via the daughtercard method would be the same as if the M.2 card were connected directly to an M.2 connector on the motherboard.

 

Honestly, there's no problem going with the plastic bracket.  Installation is easy.

Thanks very much....but in the SFF it's very hard to get to the m.2 slots! And I'm not sure how to remove the top part once I remove the cover to get to it.  So basically I need to put it in the ,4 or x16 slot...how do I know which one that is? Thanks for all your help.

The Hardware Maintenance Manual for the M910s shows the motherboard layout, oriented with "north" being up, where the CPU and rear motherboard connectors are.  The expansion slots are "south", being below the CPU.

 

The x16 slot is the northernmost big slot, closest to the CPU.  The combo slot is the sourthernmost big slot, closest to the bottom of the machine when it is standing upright.

 

You're right, the SFF cases have been getting ridiculously tiny of late, making it really quite difficult to do anything inside.  In fact you can't hardly find a graphics card worth anything that will fit inside the M910s.  I had to return the M910s I had purchased for a friend because I couldn't add the graphics card I'd picked out, expecting it to be the same size as the M900s case.  But in fact it's almost 4 inches less-deep, which is the dimension that supports the length of a graphics card.  I ended up going with an M910t instead, which is how I learned how to install the M.2 bracket for the M.2 drive I'd ordered.
