And all 9 of these sold, at asking price of $120, to one buyer ... must be a miner (or a flipper to miners).Those all seem out of stock, but there's this link with 9 available right now:

These are quite useable for anyone wanting nvme storage. I picked up two. I know someone else who bought 12+
same here. nvme doesn't show up either connecting to this directly or to a backplane. Not sure what went wrong since most people here seem fine with it.
... great ...?? How about "pretty good" ?
Aren't (most of) your host systems capable of quadfurcating (at least some/most of) their x16 slots? If so, the main feature of this card (the PCIe switch) is being wasted. You'd be just as well-served with a switch-less card for less than half the cost, and none of the heat/power usage.
].)The card contains a PCIe switch chip (a PLX PEX8734). That chip can be configured with up to 8 ports, and up to 32 lanes. On this card, the chip is configured with 5 ports (1 upstream @x16, and 4 downstream @x4 each) [these are the 5 reported by lspci], and 32 lanes [16 + (4*4)].
I got 2 cables from Supermicro's eStore. They were the least expensive than what you can buy from eBay. Both cables had the same behavior: no drive seen. Used multiple motherboards and slots were not bifurcated. I was hoping this cheaper card would give me NVMe capability instead of something from Supermicro. The only issue is there is no documentation for this card and there is a set of jumpers on the bottom of the card. Some eBay listing show half of them bridged, but this one doesn't have any installed.
I assume for the 8 ports -- it's something like 4 to the drives, 4 to the pcie bus?
I've only tested one of them and it worked fine. But you guys have me nervous so I'm going to test the rest of them.
I own a bunch of these, so probably these:
