Is this speed normal for formatting a HDD? (mint 21.2)

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.

initializing the filesystem at the same time as zeroing the drive is probably freaking the smr out and causing it to constantly rewrite tracks.
i would have separated the two operations. a sector-by-sector wipe via software which would run at the full sequential write speed the drive internals and interface supports (connecting internally would be faster), then partition and format the filesystem. being smr shouldn't matter here when you're writing sequentially, start-to-end.
alternatively for the wipe, use secure_erase (some usb don't support it though), handled internally by the drive so it runs as fast as it can. still takes awhile with hdd, but can be faster than doing it via software and being limited by the interface speed.
Stopped gnome-disks format at 78% (~6 hours remaining).
Used
#sudo dd if=/dev/zero of=/dev/sda1 bs=1M seek=1001250 status=progress
, write speed is ~100 MB/s.Thanks a ton!
