It’s certainly supposed to be 5Gbps capable.

iPad mini iPad mini 6 is still usb2.0 when connect to Mac

Interesting. I wonder if the problem is with the M1 USB-C controller. There have been numerous reports of problems with the M1 USB-C.
when use iPad mini as a host , it’s 5Gbps. Like link to a usb disk.
I am using a certified Thunderbolt 3 cable and tried both the Thunderbolt ports on my MBP and the 5G USB-C port on a CalDigit TS3+.
It shows 480Mbps on both.

Same Caldigit TS3+ dock here, have used a USB3.1 cable that happily maxes out the speed of my external SSDs but when connected to the new mini reports 480mbps in System Report. Having transferred a lot of data to my new mini I can confirm it’s definitely only running at that rate. I left it for half an hour and went and did something else while it transferred. It‘s like being back in 2010 again.
1) All mobile devices including galaxy s22 plus provide slower transfer speeds comparing to external SSDs. Not as slow as USB Flash drives but slower than external SSDS (Somewhere in the middle between between USB flash drives and external SSDs).
2) Whatever the computer says about ports or speeds of connected devices is irrelevant. We need to hear real time transfer speeds!
USB 3.0/3.1/3.2 (Gen1) real time speeds:
- Galaxy s20 FE (around 150 MB/s write and 220 MB/s read)
-Galaxy S22 plus (109 MB/s write and 120 MB/s Read)
- Standard Sandisk USB flash drive
(36 MB/s write and 130 MB/s read)
-Fastest Sandisk GEN.1 external SSD (280 MB/s Write and 460 MB/s write)
So when specs of external SSD say up to 1000 MB/s , in reality you get 280/460.
When usb flash drive clams up to 150 MB/s, in reality you get 36/130)
And phones get unspecified speeds somewhere in the middle.

M1 USB in general needs (Apple) attention: unexpected ejection, not running at full speeds, etc. Have a look at this and on a broader basis that includes some objective testing of Thunderbolt connections too, this is pretty interesting. I take all that to mean that Apple Marketing is making defensible promises that Apple hardware/software can't quite deliver now... but can probably deliver whenever Apple gets around to debugging connection hardware on Silicon Macs. I'm guessing Macs CAN do what is promised WHEN the OS bugs standing in the way of that now are finally addressed.
I continue to hope that WWDC announces a year or two of Snow Monterey.
iPhone/iPad internal storage is actually pretty fast. Unlike other companies that use eMMC (all-in-one package with controller and NAND), iPhones and iPads use a storage controller built into the Apple A-series or M-series chipset plus separate NAND chip(s).
Real world USB interface speeds are iffy though.
I don't know which other companies you refer to, but Samsung has been using UFS storage in their phones and tablets for a while. Which depending on the generation has been up to SATA and now PCIe SSDs (at least in reading, writing speeds for UFS are generally half as slow as read speeds). This of course should not be confused with the USB transfer speeds which depend on many factors. The post you quoted seems to be confusing the 2 things.
The 10Gb/s transfer speeds of USB C iPad pro, let alone the Thunderbolt speeds of M1, are only theoretical limits at this point. There are no benchmark for USB speeds on IOS but empirical tests show that not even 5Gb/s are reached in general.
