If anything I think it should be longer to accommodate 22110 m.2s if they're aiming to fit in 1U servers.

How is the performance using this via PCIe as opposed to a dedicated slot on the MOBO.

If i had to wager a guess.... I'd have to say it probably wouldn't take TOO much of a hit, performance wise. Whether it's a dedicated slot on the motherboard or using this adapter, it's still running on PCI-Express lanes. Unless it's NOT actually running on the PCI-Express lanes and that's why the SATA port is there, which would be a stupid reason to even have it using a PCI-Express 4x slot.... then there would be a pretty drastic performance hit....

Thanks, i run 3 x NVMe drives in my ARock Taichi x570, one of the reasons i got this MOBO and a dealbreaker for whatever x670 board i get. OS and Progs on one (1TB Gen 4) Steam folder on another (2TB Gen 4) Other games on the third (1TB Gen 4). I have a 2TB SSD attached and stuck on the back of the MOBO tray for any other storage.

Right, 22110 is mainly used on pro side (SLC or with error check)

For the SATA port it is the same as it doesn't use the PCIe, it is connected to the SATA port (same as previous model that is very good). For the NVME it depend if the board is wired in X4, then there is no change from motherboard one, OR if it is wired in X2 like most amazon's chinese "made in USA" crap product... then you have half of the bandwith. Also you may have to check how many line can be used with your duo mother board/CPU. It's not good: -If putting a X4 PCIe card deactivate your on board M2 (lot of Intel B*60 and AMD B*50) -If your cute PCIe (even X16) is wired in X1 or X2 on board -If your motherboard doest have a PCIe lane manager (most of the time it change your X16 used by your GPU in X8 for GPU and X8 for the second PCIe X16 card whatever pluged in)

There are already so many other options for both NVMe, SATA and mixed configurations already on the market, why do we need more? What makes this one special compared to the others?

If the adapter supports PCIe x4, it depends on whether or not the PCIe slot is wired to the CPU or the chipset. Going through the chipset will add a small bit of latency, but nothing too dramatic. I honestly doubt the end-user would notice any difference, but it would probably show up in benchmarks. If the adapter supports PCIe x2, it's obviously going to be slower. On the SATA side, it's obviously going to have the same performance since you'll still be connected via SATA cable. It wouldn't make much sense to have 1 side be M.2 NVMe specific and 1 side be M.2 SATA specific, if the card relied solely on SATA for data transfer from both drives. Relying on SATA for data transfer from both sides would also make it rather stupid to support NVMe drives to begin with.... I'm not even sure using an SATA connection with an NVMe drive is even possible, unless someone was dumb enough to make a chip specifically for such idiotic purpose.

@sykozis i asked this question when i added a third NVMe drive into my MOBO, i saw zero performance hit anywhere from the X570 Taichi when i did this.

Most NVMe drives are fast enough that the tiny bit of latency is easily overcome. As I said, outside of benchmarks, I doubt any end-user would ever notice the difference. I ran my Crucial P3 1TB on a cheap chinese PCIe NVMe card for a week as my system drive before finally replacing my Intel 660P and never noticed any performance issues whatsoever.
