Review OrangePi 4A Review: Coming for the king

What PCIe speed is supported? According to the SOC descriptions, I found it to be 2.1, which isn't very useful when you can take a Pi4 and plug any drive into USB3.0 at the same speed.
For the Pi5, it's officially 2.1, but everyone uses 3.0 and it works.
 
I agree. I dont get this article. Pi5 for nearly same money, and then buy the NVMe HAT of your choice, youur in it for about $20 more is it. With a more modern platform.
Maybe their market is commercial users who buy them in large quantities for use in other products? For them, $20 is not usually insignificant and they don't necessarily need the extra compute power a Pi 5 would provide.

NVMe isn't always used for storage - there are other peripherals that fit in a M.2 slot.
