Re: M710 Tiny drive specs?

2017-11-01, 12:54 PM
 

I am surprised to know that the M910 tiny has the additional NVME socket. I thought it is the same as the M710 tiny. It is very frastruated for M710 tiny buyer to not know this difference from their spec sheets. It is Lenovo's fault to not make clear of the actual numbers of NVME slots in two models.

 


A point of clarification:  The M910q Tiny has one M.2 PCIe storage slot, same as the M710q Tiny.  It's the M910x Tiny that has two M.2 PCIe storage slots.

I was hoping it was just soldering the 2 tabs (although against my instinct), but after doing a bit of research I found it is required to solder all the pins. It makes sense because it would be nearly impossible to ensure proper contact pressure and cleanliness.

 

This reference shows drawings of the PCB and talks about alignment of the 'solder tails' which are the pin contacts:

This reference confirms that the pin contacts are also called 'solder tails':
