I hate computer plugs. This is a mSATA? I think?

Bottom right, and dead center.  Dead center is a 500Gb drive that I'd also like to replace.

Anyone got a link to a 1TB drive?

I think bottom is m.2, not msata. Msata has two dividers, not one. Well at least the drives have. 

That's not a computer.  That's a laptop.

In reply to BoxheadTim :

I think I see what you're talking about.  I think there may be both there?

Should have posted these to start

As known, I'm a touch dense (or maybe just touched ).  So, a serious question. 
   Was that sarcasm, or implying that today there really is considered to be a difference?

I've been building desktop systems since the mid-1990's and I enjoy the relative ease with which one can install and connect various components.  While I have been inside a laptop or two, I find it very much to be avoided since everything is interlocked and there is not so much as a spare millimeter of space to be found.  Kind of like working on an inline 6 engine in an old pickup vs. a transverse mounted V-6 in a modern sedan.

Grumpy old man out!  Carry on with your little laptops! 

Actually, my bad - on closer inspection of the bigger photos I think you're right and the connector is mSata. The "divider" on an M.2 drive is much closer to the right of the slot.

Guess I should've asked how old the laptop is as that would also be a strong indicator of the connection type.

That one is indeed a mSATA (https://www.ebay.com/p/600988267). 

I think that machine has two Mata connections, just stacked on top of each other. 

Unfortunately, I don't think that there's many 1Tb drives out there in that form factor: https://www.newegg.com/p/pl?N=100011693%20600095832%20600414920

Can you get two of the 500Gb and run 'em in RAID?

A quick search of the model number yields this:

Woke up and realized that I'm an idiot.  I should work on swapping the larger, spinning disks out.

The empty slot above the wifi card is a PCI Express Mini Card (Mini PCIe) slot, most likely for a cellular modem.  It's unlikely that it will even recognize a storage device.
