Is this SSD single-sided or double-sided?

Let me clarify; the pins only connect on the one side (right in image), the shield is double-sided.

Does this SSD drive offer fast performance?

Yes, the SSD drive offers fast performance, with speeds up to 7,300 MB/s.

Can this SSD be used with a heatsink?

Yes, the SSD has an optional heatsink version available.

Does anyone know if the heat sink fits well, in terms of fitting flush. I'm a little concerned that It may get in the way of my GPU or be too close, since I will be using the M.2 Slot directly underneath/behind it?

I'm not sure about your device, but on mine there's a screw at the non-connecting end that you can synch it down with. It fits flush, but you may face another issue with it. While I wouldn't say it's bulky, the heatsink casing does take up extra space, that's for sure. It's about as thick as a standard thumb rive so I'd just keep that in mind. Would post a picture but my phone is jacked up, hope things work out well for ya.
