Most certainly not on my old Pies, USB there sucks.
USB connectors suck big time and the Linux kernel gets confused by multiple
re-connects
and renumbers the devices so nothing works anymore, then finally runs out of
device numbers,
USB3 on my new Pi4 seems fast, at least it can keep up with my typing speed,
the old Pies could not.
No kidding.

That is silly
One is on 24/7 since it came out (PI2), the other about 8/7.
Both extensively use GPIO with hardware I designed, run totally modified
software versions that I wrote.
And all are regularly connected via SSH to my laptop or main PC
and get modifications almost every week if not every day.
The 24/7 on one also logs loads of data to SDcard.

Look at his project, on 24/7:

On 8/7:

This one is on every now and then when I need it:

NONE of the cards have failed, and were just run of the mill SDcards.

My net connection at this moment is a 4G stick in an other Raspberry Pi2 that
is used as router.
It never fails.
And I do not always treat those things nicely, power off / on sequences etc.

Again it is the player, NOT the instrument
If you screw up card after card you are doing something wrong.
'
My just new Pi4 with a 4TB harddisk hanging from it boots also from SDcard.
It is taking over much of the other things like security that needs to run
24/7,
satellite recording (movies) etc etc, work in progress.
Just had it 3 weeks OK?

So what can you show us?
