From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Sorry for the nitpick, but you probably mean GB/s (or GiB/s, but I won't go there). Gbps is gigabits per second, not gigabytes per second.
Since both are used in different contexts yet they differ by about a factor of 8, not confusing the two is useful.
I think it is gigabits per second, but to be clear: Whatever dd reports as speed after finishing (or with status=progress)
That's in bytes. A modern NVMe drive can do about 7 GB/s (more than 10 for PCIe 5.0 drives). Even SATA could handle 5 Gbit/s, though barely.
Yup, my PCIe NVMe should be readable at 8 GB/s and writeable at 7 GB/s afaik. I can't reach that speed tho, no matter which bs.
