Looks like the card is PCIe 4.0 x4, which gives about 8GB/s. Not sure if this board is driving the RAM at full speed, or how many controllers there are, but more lanes could make this faster.

Looks like one controller per lane, so if this 4x card finds a good market we might be looking at 8x or 16x siblings in the future.

This isn't a good device for most home users, but for businesses that cache a lot of high speed data this could be a useful tool.
