Unlike magnetic devices, flash usually don't leave any significant traces of previously recorded data. Writing new data usually is page erase - page write cycle. So, really, it does not matter what data will be written. So, fast urandom is good enough. To be paranoid you could write it twice.
There is another thing in flash-based devices that could be potentially dangerous. Flash devices usually have some spare memory to use instead of failed blocks. And once internal processor finds bad block it just replaces it with spare one. And data recorded in bad block still stay there and can't be erased by usual means. From the other side, if flash begin to fail, than it fails fast and become unuseable. So it makes no any sense to keep such device at all and it could be just crashed or microwaved to destroy all data,
But better approach is to use shred -v /dev/sda adding whatever options you think you need to carefully erase all data. This command is part of coreutils and every single linux distribution have it out of the box.
Also, some disks have internal "secure erase" command, but I would not depend on it since nobody except manufacturer knows what that command really do.
It was always a huge mistery for me why anybody would use any Apple crap at all.
Every single Apple device I ever played with is a total crap from all possible angle from useability to repairability. That things are unuseable. Every single one, from that insane single-button mouse to all that modern iPhones and iPods. Even relatively conventional MacBooks have permanent and irrepaireable design flaws that make them not the best choice even if you wipe out that shitty macOS and install Linux. Moreover, even if you need to use some software that exist only for macOS it is easier to run that piece of shit in VM on any PC or, say as a second system on old "hackintoshed" ThinkPad T450 from garbage bin.
How people who fall to using that crap can't see it is a total crap? And I'm not talking about total vendorlock and incompatibility of Apple products with anything else.
Does marketing have so much control over not only minds, but over such unconscious thing like ergonomics?
I was with the wall of text until you tried to claim a plugged in iphone takes 3-5x longer. Not to mention missing a chunk of the story where I'm guessing they somehow tried to get your posts taken down?? These larps suck.
On my 2019 laptop I went thru a tutorial on unhiding files, found the hidden temp folders and low and behold found pictures of me , my girlfriend at the time pictures We were not taking when We used the laptop.. topless pictures staring at the LCD screen. Windows was taking snapshots of us and saving to hidden temp file!! That you know was being sent to Microsoft during their auto updates. Go back to desktop builds with no cameras or mics builtin! Less is more these days
they were mostly disheveled pics of me or her from what looked like they were taken everytime to laptop was awakened from sleep. The cool thing was that laptop was disconnected from the internet and used for emergencies or going on road trips for wifi connectivity (that was turned off most the time as well)
/dev/urandom
/dev/urandom is a source of pseudorandom sequence, /dev/random is "true" random so /dev/random could be slower.
I think for erasing flash-based devices like SSD, USB-sticks or flash cards you could use /dev/urandom with same efficiency.

Could be just cat /dev/random > /dev/sda

They also force you to continuously upgrade to the newest version of iPhone in order to be able to use various apps.
And they limit the apps you can use.
Anyway, this is one of the reasons it is standard practice for higher level govt workers to physically destroy their tech with hammers or whatever.

“Secure erase trash” doesn’t even exist anymore. What you want is to encrypt the disc using FileVault and then lose the password.

Fb people and others always have their camera covered.
