Thanks guys.
I don't understand much of what a lot of writes on disk involves exactly
(changing location of files, things like that?), but looking for it on the
web, I found this (https://askleo.com/can_a_usb_thumbdrive_wear_out/):
The best use of USB thumb drives and other flash memory-based devices is
simply copy-to and copy-from. By that I mean copy the information to the
thumbdrive to store it, copy it from the thumbdrive to a local hard disk to
use it, and then copy it back to the thumb drive to store it.
Never run disk-intensive applications directly against files stored on the
thumb drive.
If you copy to and from even ten times daily, you’re looking at three years
of usage for the low end of the flash memory lifespan. (Yes, I know that’s
not exact. In fact, it’s way more complex than that; factoring in things
like the type of file system, FAT or NTFS, the efficiency of the device
driver, and even the circuitry on the specific flash memory device – but
it’s a good order of magnitude.)
You may also note that your application speeds up when you copy your database
to the hard disk for use. While reading flash memory is typically quite fast,
writing is not.
So the best strategy as a user for longevity would be to copy to and from the
NAND, but not use applications that do this often (can't figure out examples.
maybe intensive saves from a video editing software?)?
but since there's a possibility to have external memory cards, I suppose it's
possible to use the 8GiB of NAND for anything that's not meant to move often.
Supposedly, reads wouldn't affect its longevity as much as copying to and
from.
