Precision 7710 - Drive Adapter Interposer Connector and Cable - WYWRF

[ygohome]

Hello,

 

I have a Mobile Precision 7710.  It has two slots for PCIe Gen3 NVMe M.2 SSDs.   It also has a 2.5" SATA3 drivebay caddy, near the removable battery.  I currently have two M.2 PCIe SSDs.  I'm considering a 3rd to put in that vacant 2.5" area.

 

Dell has advertised that it is possible to install a PCIe m.2 SSD in that 2.5" area by purchasing a  Interposer Connector and Cable.

 

Does anyone know if that interposer allows for PCIe Gen3 SSD speeds?  (for example up to theoretical 3500MBps?)  Or will it be limited to SATA3 SSD speeds of about 550MBps?

 

I'm also unsure if I'd need anything else to secure an 2280 M.2 in that area where it's normally meant for a 2.5" drive.  Will it just flop around in that caddy area or do I need to order another part I'm unaware to secure it?

 

Thank you,

 

Benny

 

Edit:  *I was wrong about WYWRF, that is just the normal already existing connect for SATA drives.  Please read my follow-up replies further below

Actually, I'm not sure I have the correct part linked above.  That might be the connector for a regular old SATA drive and not for an m.2 NVME SSD.  I need to do some more research.  I'm pretty sure I remember way back when Dell said we could purchase an interposer cable connector to use m.2 in that 2.5" area.  I need to find the correct cable part.  I'll be back after I research more.

Now I just need to find out where to buy all these weird parts

 

Found them:

Y1WJX - M.2 bracket  and WPTND - M.2 Interposer Board  together as a set:

Found the thermal cover directly from Dell:

Very cool.  Still, I'm not totally sure these will supply PCIe Gen3 NVMe speeds, but I think they will. We shall see.

I seem to remember that this drive ran at a lower speed than the others.  I think it is still PCIe3, but two lanes instead of four.

[Edit] I think that is what the "4X" and "2X" mean in the table that you have embedded above.

Done that for my 7710 and one of my 7510s, the only real inconvenience is cost as sellers tend to overprice the adapter.

Ahh, yeah.  The chart does say that the 2.5" area has x2 PCIe Lanes instead of x4 lanes.  It'll be faster than sata though, so that still good
