As for Ultra M.2 vs. normal M.2 comparison, we tested the read speed of Samsung XP941 PCIe x4 M.2 SSD on Ultra M.2 socket and reached 1.16GB/s, 46% faster than PCIe x2 M.2 socket.

It supports M.2 2232, 2242, and 2280 SSDs with speeds up to 800MB/s thanks to support for PCIe 3.0… even though the Raspberry Pi 5 only officially supports PCIe 2.0, which Pimoroni notes ...

StarFive VisionFive 2 Lite is a low-cost, credit card-sized RISC-V SBC powered by a 1.25 GHz JH7110S quad-core 64-bit ...

Technically, M.2 connectors are rated at 0.5 A per pin, so, M-key with its nine 3.3 V pins would result in 4.5 A max – that said, the recommendation for M-key is to not exceed 2.5 A, and that ...

It also includes Hyper M.2 x 3 and M.2 2230 x 1 expansion slots, as well as Realtek ALC897 audio chip and Gigabit LAN by Realtek 8111H network. The motherboard measures 244 x 244mm.

There's a lot to unpack, starting with the fact that there's more than one kind of M.2 connector, more than one type of interface that can be used with M.2, and more than one kind of M.2 card.
